The Importance of Water Filters

The Importance of Water Filters
Pure water is tasteless, but water is a powerful natural solvent that dissolves minerals that may give it an odor or flavor. Today, people are in dire need of purifying water (water) to make it drinkable, due to the expansion of urbanization and the increase in population density in the world and the distance of many cities and residential neighborhoods from sources of pure water (water) such as rivers and springs, in addition to the increased rates of pollution in water (Water) in general.
Hence The Importance of Water Filters, which have become a necessary necessity in every home because water contains dirt, minerals, chemicals and other impurities that make it smell and taste bad. Some of these contaminants can endanger human health, especially when they include microorganisms and bacteria that can cause serious illness.
Water filters (water) will help filter water (water) and purify it from harmful bacteria and parasites and remove these impurities and make it drinkable, while often improving its taste.
Harmful substances treated by water filters (water)
metal
Iron and other minerals, such as calcium and manganese, are not dangerous to human health, but they can change the taste of mineral drinking water. Their presence in used water can cause stains to appear on clothes when the wash water contains these elements, and they can even discolor porcelain and other dishes washed in mineral-rich water. These minerals can also build up in water pipes, gradually clogging them and reducing water pressure, which can cause plumbing problems.
chlorine
Chlorine is very effective at killing many bacteria in the water, and it can also kill some viruses, so most municipal water utility companies use chlorine to treat drinking water because it is inexpensive and easy to use.
But despite being a good disinfectant, chlorine can make drinking water smell and taste unpleasant, and it can also react with some metals to form dangerous compounds. The activated carbon filter removes the odor and taste of chlorine from the water.
dangerous lead
Lead usually gets into drinking water when it seeps into the water supply from old plumbing pipes or the solder used to connect them together. Lead is toxic when ingested, so health agencies recommend a good test at least once a year for lead and other contaminants.
Lead can be removed from water through reverse osmosis, distillation, and carbon filters designed specifically for metal removal.
Pesticides and chemicals
The most common pesticides, prior to the 1940s, contained heavy metals that did not dissolve easily in water. Modern organic pesticides are water soluble and can easily reach the water supply. Activated carbon filters can remove pesticides and VOCs from drinking water.
sulfur
Sulfur-containing minerals are found in most rocks and soils around the world, and when groundwater (water) seeps through the ground, some sulfur compounds dissolve in the water. Rainwater is also a source of sulfur, which makes it more present in well water than in municipal water.
The biggest problem with sulfur in drinking water is that it stinks, so water containing hydrogen sulfide can be quickly identified with its sulfur smell. Drinking water that contains sulfur does not pose a health risk, but it may be unappetizing.

Sand Filter

Sand Filter
is a filtration solution that helps maintain water (water) quality in water facilities and life support systems. Filtration is an essential component of water treatment for swimming pools, water slides, spray platforms, fountains, life support systems, and other bodies of water in aquatic facilities.
is used to remove suspended, floating and sunken materials and particles to keep the water (water) clean with less chemical use. In addition to suspended matter, COD (chemical oxygen), BOD (biochemical oxygen), organically bound nitrogen and phosphate, and undissolved minerals are also removed from wastewater.
How does it work?
It consists of sand layers, so that the larger grains of sand are present in the lower layer acting as a support, and the smallest grains are in the upper layer. Thus the wastewater (water) flows vertically through a thin layer of sand and/or gravel, and the particles are then removed by adsorption or physical encapsulation.
The work of the sand filter can be divided into two functions:
Surface filtration, through which particles collect on top of the filter layer. Together, these particles form a large porous mass, capable of collecting new particles in a very efficient manner.
Depth filtration, through which smaller, difficult-to-collect particles collect and bind to sand particles through adsorption.
The dirt generated by surface filtration during back rinse is easier to remove than the dirt from deep filtration. To reduce particulate build-up on the filter, an initial sedimentation step is performed for heavily loaded wastewater (lots of suspended and sinkable matter), which helps to avoid frequent filter re-rinsing.
Benefits of a sand filter
It can be said that the main benefit of a sand filter is that it is a simple system that can be used to get great returns. Therefore, sand filters are used in various sectors and processes, where far-reaching removal of suspended matter from water (water) or wastewater (wastewater) is required.
Another benefit is that the sand filter can be placed in different stages of water (water) management: as a pre-treatment, as a side-stream filtration, or as a polishing filter. A sand filter often provides a liquid flow with the possibility of reuse.
Here are some examples of sand filter uses:
Iron removal from ground water using aeration and sand filtration.
Final purification of wastewater, follow-up of mineral deposition and sedimentation to remove residual traces of mineral-based sludge.
Final purification of waste water from the production of iron, steel and non-ferrous alloys. Sand filtration can be preceded by processes such as sedimentation/ sedimentation, coagulation/ flocculation/ sedimentation and flotation.
Purification of waste water (water) containing sand-rock particles and paint particles, for example in shipyards.
Also used as final purification (or before activated carbon filtration) to allow reuse.
Slow sand filters are also used in greenhouse gardening (gardening that reduces greenhouse gas emissions and stimulates soil and plants to absorb carbon dioxide in order to help reduce global warming) so that it acts as a wastewater disinfectant.
Disadvantages
Despite its benefits, sand filter filtration sometimes requires the addition of chemicals to improve filter yield.
One of the disadvantages of sand filtration is the rinse water that forms when cleaning the sand filter. This water (water) is highly polluted and must be treated and disposed of.
Neglecting to backwash the sand filter regularly and correctly may cause channels to appear inside the sand filter, which will cause the sand inside to become stony and thus increase the problem of clogging of the sand filter.

The Importance of Filtration in Water Treatment

The importance of filtration in water treatment
The importance of filtration in water treatment lies in the importance of water (water) itself in human life on Earth’s surface. There is no difference in the fact that water (water) is such an essential part of our daily life that we often do not stop thinking about its source or quality, and we always strive to reach the best possible result to drink pure water that contributes to hydration and enhances the health of the body.
Many people consider tap water to be unfit for drinking, and here comes the role of filtered water and the importance of filtration in water treatment in order for people to have clean water that is free of pollutants, tastes good, and provides the required hydration for the body. Thus, the lack of filtration exposes the water drinker to the risk of various diseases caused by polluted water, especially infants, the elderly and people with weak immune systems, because they are the groups most vulnerable to harmful effects due to polluted water from the tap.
Reasons for resorting to filtration in water treatment (water)
Public water systems apply filtration protocols that differ from one country to another, but they all provide the basics of the water purification process (water), although people in different countries seek to choose a private filtration system as an increase in security and confidence, water filtration systems may be outdated Lead pipes are used that cause lead to leak from the pipes into the water.
The spread of lead or other pollutants and heavy metals can lead to health problems such as kidney and respiratory problems, reproductive difficulties and cancer, as well as damage to the skin and hair. For all this, we find that drinking water that has not been filtered from heavy metals and impurities is not desirable for many people, and therefore they seek to have a special water filter at home. The filtration process has been likened to the function of the kidneys in the human body, as both have the same role in purifying fluids and getting rid of toxins.
Fortunately, there are several ways in which people can obtain filtered water. The water filter has microscopic holes that remove sediment and contaminants from the water. The smaller the holes, the less contaminants are allowed to pass through and the cleaner the water. The way each type of water purification system works is slightly different. The most common options are sand filters, reverse osmosis units, and alkaline water.
Sand filtration steps in water treatment
The sand filtration process includes several important steps, which are explained in the following points:
The water is entered through a filter called the gravity sand filter, which is a rectangular water tank, consisting of three filter layers: the first layer is thin and long, the second layer is thick and short and consists of sand, and the third layer is thick and short as well and consists of Gravel, this filter removes impurities and microorganisms by 98% to 99%.
The water that was purified in the previous step collects at the bottom of the gravity sand filter, and then the water is covered with a layer with a sticky texture called the bio-layer, and this layer consists of bacteria, algae and diatoms.
In the biological layer, the remaining microorganisms appear more clearly, then the oxidation of the organic materials in the water occurs, and the microbial cells are filtered.
An activated carbon element is placed at the base of the filter to remove unpleasant odors and toxins.

Sea Water Desalination Methods

Sea water desalination methods
Reasons for resorting to methods of desalination of sea water
According to the World Health Organization, around 785 million people globally lack a clean source of drinking water close to where they live, needing to walk half an hour to reach it, and this problem is getting worse as the global climate crisis continues.
Given that saline water constitutes about 97 percent of the water on the planet, scientists view sea water as a large untapped resource for life-giving drinking water. world level.
Reverse Osmosis
Osmosis is the net movement of water molecules across a semipermeable membrane from an area of high water density (example: fresh water) to a region of low water density (example: salty sea water) without the need for energy consumption, because the semipermeable membrane allows the permeability of water (solvent). ) and does not allow the solutes to pass through, which leads to a pressure gradient across the membrane.
Reverse osmosis requires the use of energy and pressure to push the water solution through a permeable membrane that prevents large dissolved particles, such as salt, from passing through it.
The downsides of this process are:
The membranes in them during their use are exposed to the accumulation of a lot of bacteria on them, which may lead to clogging, although they have become more effective over time, and these membranes are damaged when chlorine is used in them to treat bacteria.
Poor water quality.
The need for a pretreatment of salt water.
Consuming a large amount of energy.
electrical separation
Through this technology, sea water is desalinated by using electric current to separate water from salt, so that the electric current isolates sodium and chloride ions from sea water through a selective permeable membrane. They can be thrown out. One of the downsides of this process is that it is considered a suitable process for desalinating water in which the salt concentration is primary, but it also consumes a lot of energy to desalinate sea water.
multistage flash
The multi-stage rapid distillation process is applied based on the scientific fact that determines that the boiling point of liquids is directly proportional to the pressure on them. The lower the pressure on the liquid, the lower its boiling point. This is how sea water passes after being heated to successive chambers of low pressure, and the water turns into fresh water vapor that is condensed on cold surfaces, collected and treated in potable quantities. This method is used in desalination plants with large production capacity (30,000 cubic meters, or about 8 million gallons of water per day). The remaining salt concentrate is known as “brine”, and no chemicals or softening agents are usually added to the water.
Multi-effect distillation
The multi-effect distillation process is similar to the previous process (multi-stage flash distillation), in which the multi-effect distillation takes advantage of the vapors rising from boiling sea water in the first evaporator to condense in the second evaporator. The same process is repeated in the third evaporator, by spraying the feed water on the group of tubes above each evaporator. Thus, each evaporator in that series is called the effect, whereby the water vapor condenses to turn into fresh water inside the tube, and then it is pumped into special channels.
Forward Osmosis
Forward osmosis uses the naturally occurring osmotic process, namely the movement of water molecules across a semipermeable membrane from an area of high water density (example: fresh water) to an area of low water density (example: seawater). This process requires about half the cost of the reverse osmosis process because it consumes less energy to complete the process. However, since it is still a new technology for large-scale desalination, this process needs funding and research to explore its implementation possibilities, aspects that need improvement, and improvements required to reduce energy costs.

PMFs
This new innovation developed by scientists in Australia is the most successful to date, with researchers using MOFs (or MOFs) combined with sunlight to purify water in just half an hour, using a more efficient process than existing technologies.
One of the advantages of these compounds is that they are cheap, stable, reusable and produce water that meets WHO standards for desalination. About 139.5 liters (approximately 37 gallons) of clean water can be produced per day from a kilogram of PFs based on early testing.

Reverse Osmosis Filters

Reverse Osmosis Filters
are best for their ability to remove a large percentage of contaminants from the water, including dangerous waterborne bacteria. These filters work by forcing water through a reverse osmosis membrane using pressure.
There is no life on this earth without water. Nature does its part to recycle the amount of water on the planet to meet humanity’s massive water needs, however, the fresh water that humans need to survive is a tiny fraction compared to salt water and polluted water. That is why for a number of years people have used a reverse osmosis water filter to ensure the cleanest water possible.
Polluted water in its journey through reverse osmosis filters passes through several filtration stages, the most important of which is the reverse osmosis membrane.
Reverse osmosis membrane components
The reverse osmosis membrane is a carefully designed, multi-layered semi-permeable membrane. The reverse osmosis membrane is made of polymers such as polyamide and cellulose. Polyamide can be manufactured, or obtained from natural sources, such as wool and silk. Cellulose membranes are the oldest, having been in use since 1955, but polyamide is more efficient.
The pore size of the reverse osmosis membrane is less than 1 nanometer, about 90,000 times smaller than the width of a human hair. These filters remove all germs in the water, along with other fine chemical compounds that may be present in it.
How do reverse osmosis filters work
Its work through several steps:
Initially, water from building pipes or any other source enters the reverse osmosis filter and passes through a pre-filter, whose job is to filter the water of all large particles, such as sediment, dirt and rust that may come through the water pipes. This filter is relatively inexpensive and increases the overall life of the reverse osmosis filter.
After passing through the pre-filter, a pressure pump is used to push the water through a reverse osmosis membrane capable of removing microorganisms and TDS present in the water. Dissolved solids include the minerals and organic molecules found in water. The water that passes through the reverse osmosis membrane is 97-98% free of dissolved ions and 99% of germs.
Some reverse osmosis filters may also contain post-treatment filters, which improve the taste of the water. This after-filter contains mineral balls that selectively regenerate the good minerals lost during the reverse osmosis process.
Waste and dirt leave the filter through another pipeline connection that goes to the sewer.
The final product coming out of the filter is clean, potable fresh water.
Pollutants that reverse osmosis filters can remove
The reverse osmosis water purification system is known to eliminate 99% of the pollutants in the water. These include:
chlorine and fluorine
Lead, arsenic, chromium, radium, barium and cadmium
Salts – nitrates, sulfates, etc.
Sediment, Dirt and Rust
heavy metals
Parasites
Volatile Organic Compounds (VOCs)
Herbicides and Insecticides
Total Dissolved Solids (TDS)
Where can reverse osmosis filters be used
Reverse osmosis filters are used to purify domestic drinking water, and are also used on a much larger scale in sewage treatment plants, water desalination plants, and plants that extract salt from water, this method is also used to make seawater drinkable, and it allows ships at sea to purify seawater For fresh drinking water.
Disadvantages of reverse osmosis filters
Although they are considered the best at purifying water and making it drinkable, reverse osmosis filters have the disadvantage that they are difficult to maintain.
If the pump experiences any malfunction that may cause the water pressure to drop, this means that the flow of water through the reverse osmosis membrane will be very slow. This will increase the time it takes for the reverse osmosis filter to purify the water.
If the filters are not cleaned regularly, this can lead to clogging of the reverse osmosis system and the formation of bacterial biofilms inside the device, further contaminating the water coming from the pipes.

Sand and Carbon Filter

Sand and Carbon Filter
The sand and carbon filter is used after the water (water) purification process to achieve the complementary removal of solids and disease-causing contaminants that are still suspended and not destroyed. The sand and carbon filter is equipped with an automated backwash system in order to maintain a high level of efficiency.
Why do people care about water (water) filters?
Most people are interested in drinking pure drinking water that does not contain minerals and impurities, and therefore does not lead to health problems such as cancer, kidney and liver diseases. They are also interested in obtaining pure water (water) that does not affect the growth of children, so they all resort to buying filters to purify the water (water) to be suitable for drinking.
The sand and carbon filter is effective for removing impurities, taste, color, odor and their pathogens, gases and chlorine from drinking water (water). However, the first correct step in this field is to test the tap water in the home or institution by accredited laboratories, in order to find out what it contains of impurities, and then choose the appropriate filter based on the result.
It is also necessary to maintain the filter after its installation, by maintaining it, and cleaning it from time to time from the pollutants that accumulate in it.
Sand and Carbon Filter Components
Multimedia filtration and activated carbon systems have gone through many stages of troubleshooting to obtain satisfactory results, and today these systems use the following media: silica sand (silica), anthracite, activated carbon and gravel.
Silica sand (silica) is a granular material containing quartz and minute amounts of coal, clay and other minerals, and is universally regarded as a highly effective filter media. Silica sand (silica) is also known as quartz sand and artificial sand. Silica sand specially graded for water filtration systems can block sediment and impurities from water (water).
Anthracite is black coal that contains more fixed carbon than any known coal on the planet. It has been used as a method of water filtration since ancient times. Anthracite is crushed for use as a medium-density filtration medium.
Activated carbon is a strong black charcoal that has a lot of pores with a very large surface area. Activated carbon is used to remove chlorine and some types of heavy metals attached to organic molecules. Activated carbon removes more water pollutants than regular carbon.
Gravel is a semi-angular, firm, durable and dense grain of mostly siliceous material. Its physical properties are among the world’s best available for water purification applications.
Carbon Sand Filter Efficiency
The efficiency of the sand and carbon filter depends on several factors, the most important of which is the turbidity and the total (suspended solids), as with the increase in the proportion of plankton and turbidity, the amount of the components of the sand and carbon filter and the capacity of the filter or container must increase, in order to increase the period between the cases of saturation of the filters with sediment and plankton. , thus increasing the time between backwash operations and increasing filter efficiency.
During the backwash process the water flows in the opposite direction to the normal flow of the service. The backflow rate must be high enough to allow the pollutants from the loose filters to escape away into the wastewater through the wastewater pipeline where they are disposed. The backwash process takes about 10-15 minutes, then the filter is clean with high efficiency.

Multimedia Water Filters

Multimedia water filters
Multi-media water filters or (multi-media filters) are a pressure filtering vessel with three or more different media on top of the gravel layer. Hard coal (anthracite), sand, and garnet are often chosen because of their different sizes and densities. Hard coal (anthracite) is the lightest, then sand, then garnet. The gravel is usually at the bottom as a support to keep small media out of the distribution system and to stop water being directed.
Filtration is the process of removing solids from a liquid by passing it through a porous medium. Coarse, medium and fine porous media are used according to requirements so that the physical composition of the filter media varies greatly according to the nature of the contaminants needed to be removed. This filter media thus prevents the passage of contaminants through physical obstructions, chemical adsorption, or a combination of both.
Multimedia sand filtration systems also known as depth filters or turbidity filters, usually used for commercial and industrial applications, are the most common type of water filter to date.
Why do we need multimedia filtration systems
The multimedia filter is used to reduce the level of turbidity and total suspended solids in the water to be treated. These suspended solids consist of small particles such as silt, clay, gravel, organic matter, algae and other microorganisms.
If multi-layered filters are not used as initial treatment, it can cause a high proportion of suspended solids, which leads to a pressure drop and reduced effectiveness of the rest of the water treatment equipment, filters, membranes, reverse osmosis membranes, EDI system, and UV sterilizers. Ultraviolet and ion exchange systems. Therefore pressure vessels containing sand or other bulk media are widely used to reduce the level of suspended solids (turbidity) in incoming water.
Work history with multimedia water filters
The use of water filters as a method of water purification began as early as 2000 BC in ancient Egypt. The filtration then evolved from the simple Hippocratic fabric housing to the complex solid carbon block and multi-media water filters currently on the market. Water purification using multimedia water filters is now the first and best way to purify water, removing more water pollutants more efficiently than any other technology.
Multimedia Filter Components

Filter tank: either stainless steel, FRP fiberglass or epoxy coated steel.
Filter layers: different layers of gravel, silica sand #20, gravel, hard coal
Upper and lower inner distributors: Either PVC 80 or stainless steel

Valves: electric or pneumatic automatic valves for automatic filters, or manual valves for manual filters.
PLC control: or digital control system
Interface tubes: PVC 80, stainless steel or epoxy-coated carbon iron
Flow Control: On the Wastewater Side

The difference between multimedia filter and sand filter
A typical sand filter is a single media filter, because gravel is a non-filtration layer. In a single media filter the smallest particles travel over several backwash cycles to the top of the media bed while the larger and heavier particles settle to the bottom of the filter. Most filterable particles are trapped in the source water at the top of 1-2 inches, as smaller media particles have the smallest spaces between them, and this is an inefficient use of media depth.

How to choose a multimedia filter
Choosing a multimedia filter depends on several different factors that must be considered in order to achieve good filtering results:
Maximum flow rate required
Nature of suspended solids or turbidity (colloidal or non-colloidal)
Analysis of the water to be treated
Required quality of treated water
Provides enough water for backwashing

What makes multimedia filters special?
It is easy to clean.
It is used to treat large amounts of pollution in water, as it is used when the value of the plankton density index is greater than 3, or when the turbidity is greater than 0.2 NTU, in order to prevent premature sedimentation on reverse osmosis membranes and microfiltration. All film manufacturers require plankton treatment to be less than 3, otherwise the warranty will not be valid.
Reduces the need to replace filter cartridges or bags, and reduces labor effort.
It has the ability to “backwash”. Backwashing is the purification and cleaning of the filter from the accumulated and filtered particles so that the filters’ high performance is restored.

Carbon Filter

Carbon Filter
Many people use the carbon filter to purify drinking water in homes, institutions, and companies, to ensure the quality of the water and its suitability for drinking. The presence of pollutants, and the increase in the percentage of chlorine in the water, all affect the quality and taste of water. It also affects human health, and the expected benefits of drinking water, which is the basis of life. Carbon filters are also used as a pre-treatment process for reverse osmosis water, and as specialized filters designed to remove chlorine-resistant cysts, such as Giardia and Cryptosporidium.
Therefore, many people are keen to choose the appropriate and reliable water filter, and the types of water filters vary in their prices according to the degree of their quality, and the number and type of candles inside the filter.
Definition of carbon filter
A carbon filter is a device for filtering water from pollutants and impurities. A carbon filter, also known as carbon filtration, uses a piece of activated carbon designed to filter out as much of the pollutants as possible in the water.
Carbon media can be made from many materials such as coconut shells, bamboo, fruit peels, and charcoal most famously. When processed through the “activation” process, the carbon media will open a large number of pores that enable the carbon to capture contaminants, which is known as “adsorption / attraction / adsorption”. Activated carbon adsorption function is widely used in residential, commercial and industrial water purification process.
What is active carbon
Activated carbon, or activated charcoal, is a porous charcoal with a very high surface area, and has a great ability to chemically absorb gases and toxins around it. Therefore, it is multi-use, especially in the purification of polluted water and wastewater for drinking, agriculture and industrial use. It is also used to kill bacteria and remove bad odors from the air.
Carbon filter properties
A carbon filter is most effective at removing chlorine, sediment, and volatile organic compounds (VOCs) from water. However, it is not effective in removing dissolved minerals, salts, and inorganic compounds. Typical particle sizes that can be removed by carbon filters range from 0.5 to 50 µm.
The efficiency of the carbon filter also depends on the flow rate of the water. The slow flow of water makes the carbon filter better able to absorb pollutants of the right size.
Types of carbon filter
The most important types of carbon filters used in the filtration industry: bulk powder filters, and activated granular filters. Many carbon filters also use secondary media, such as silver or KDF-55, to prevent bacteria from growing inside the filter.
Does using a carbon filter harm mineral salts?
Dr. Helmy Al-Zanfali, Professor of Water Pollution at the National Research Center in Egypt, answers, saying: “The cost of separating mineral salts from water is very high, and it needs advanced devices that cannot be placed in a small filter of such types,” adding that the water problems are different and multiple, Including the high percentage of chlorine and impurities, and the increase in water salinity, so it is necessary to determine the main problem in the water before purchasing the filter, and to choose the type of filter based on it.
Tips when using water filters
Buy filters from a trusted source and make sure of the brand.
– Ensure the availability of spare parts and original spark plugs.
– Do periodic maintenance on the device by the manufacturer.
Purchasing a salt meter to test the quality of water and the percentage of salts it contains.
– Change the candle of the device when you feel a different smell or taste, even if the specified period has not passed yet.
– Clean the filter periodically according to the manufacturer’s recommendations.

Alkaline filters

Alkaline filters
People often wonder what water (water) is the healthiest for drinking, especially after diseases have increased due to the spread of pollution and harmful substances in the air, water and the basic resources for life.
The purity we seek in our daily drinking water is closely related to its pH, so spring water is the healthiest to drink when it is obtained, stored safely and minimally processed, because it provides the rich minerals that our bodies crave hard.
Can the alkaline filter provide the person with the alkaline water he needs, as long as he cannot obtain spring water from its natural sources? This is the second question that we will try to answer in this article.
Alkaline water
What is meant by the word alkalinity in water is the pH, and the pH level is a number that measures how acidic or alkaline substances are, on a scale from 0 to 14. When the “PH” is less than 7, this means that the body has become acidic, and when it is Above this level, the body is alkaline.
Dr. Otto Warburg, winner of the Nobel Prize in Medicine in 1931, specifically in “physiology”, was the first to point out that all types of cancer occur due to an acidic environment, meaning that cancers do not live in an alkaline environment, and that cancer is simply It cannot grow or survive in the alkaline body.
Alkaline water is rich in alkaline compounds, including calcium, silica, potassium, magnesium and bicarbonate.
Alkaline filter work
The alkaline filter works by filtering microplastics, chlorine, heavy metals, bacteria and chemicals and purifying harmful acids present in the water, while retaining important natural electrolytes, thus converting drinking water into alkaline mineral water that hydrates the human body quickly and efficiently. Therefore, alkaline water is considered healthier than reverse osmosis water because it contains minerals that are necessary to complete a healthy human diet.
The alkaline water produced by the filter contains H20 clusters which are smaller in size, thus the human body can digest and absorb it more easily.

Health benefits of alkaline water
Despite the proven benefits of alkaline water to the human body because it contains natural minerals, scientific research is still underway to reach sufficient scientific evidence to support the use of alkaline water as a treatment for certain diseases. Among the general benefits of alkaline water:
Improve bone health
Slow down the body’s aging process with liquid antioxidants that absorb more quickly into the human body
Improving digestive health by producing more gastric juices and digestive enzymes.
Reducing the risks of cancer and heart disease.
Colon cleansing.
Support the immune system.
Moisturizing the skin and promoting its health through its detoxifying properties.
Weight loss.
Boosting pH levels in the body.
Alkaline ionized water can be considered as a key safe strategy in the management of metabolic acidosis due to renal failure, hemodialysis or urinary diversion.
Helping the body metabolize nutrients and expel toxins.
Allow more fluid to be retained in the cardiovascular system.
Enhance the body’s ability to buffer and neutralize acidity, thus improving performance in athletes.
Aiding in alkaline diuresis, which rids the body of some environmental toxins and pharmaceuticals.
Lowering blood sugar levels.
Reducing allergic reactions.
Combating damage caused by free radicals.
