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seek to choose a private filtration system as an increase in security and confidence, water filtration systems may be outdated Lead pipes are used that cause lead to leak from the pipes into the water.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.
