]]>Water Treatment Gravel Filtration Media is extracted from Saudi Arabian purest quartz Gravel mines and manufactured though an active processing control program monitoring material by the process of washing, drying and grading as per stringent specifications standard of ANSI/AWWA B100-09 and ASTM E11 test sieve standards.
Gravel is used in Water Filtration with water treatment Filtration products Silica Sand, Anthracite, Activated Carbon, Birm, Pumice and Garnet in portable water treatment, surface water treatment, swimming pool water treatment, R.O. reverse Osmosis treatment plant and wastewater treatment also in conventional water treatment filters. Filter Gravel is an extremely effective filter media because of its ability to hold back precipitates containing impurities. Filter sand size, angularity and hardness are the important filter sand characteristics to ensure proper filtering. In slow sand filters, the gravel is normally on the bottom layer and is used as channels for filtered water to make it to the outlet lines. Sand will often plug the holes in the outlet pipe and the gravel helps prevent that. The primary role of the gravel in the bio-sand filter is to prevent clogging of the PVC pipe with sand. The first layer is sufficiently deep to cover the inlet to the pipe and should be large enough to keep the openings in the filter bottom free for the flow of water out of the filter, and the upper layer fine enough that the overlying filter sand will not sink into its pores.
Sand and gravel are used for road construction, for mixing with asphalt, as construction fill, and in the production of construction materials like concrete blocks, bricks, and pipes. It is also used to make roofing shingles, used on icy roads in the winter, for railroad ballast, and water filtration. The quarry is often where our gravel and other aggregates are excavated and where rocks such as sandstone and basalt are crushed down to size.

]]>Water Treatment Pumice Filtration Media is manufactured under high quality control monitoring program subtracted from high purity pumice mines reaching to our factories located in Saudi Arabia for minerals treatment processes which includes washing, drying and grading to meet the strengths specifications standard of ANSI/AWWA B100-09 as per ASTM E11 Test sieve standards. Pumice used in sand filters for Water Filtration with other water treatment filtration media products such as Gravel, Anthracite, Silica Sand, Birm, Activated Carbon and Garnet. As a filtration media, pumice is used as an aggressively-filtering alternative to sand (and other filtration media) for the treatment of municipal and industrial effluents. The low specific gravity and high porosity of pumice make it ideal for these applications and treatment processes. A growing body of research has shown pumice to be an effective filtering media for drinking water. The foamy structure and near-white purity of Hess Pumice makes it ideal in the capture and retention of cyanobacterial toxins and other impurities found in fouled drinking water.
Pumice is a light-coloured, extremely porous igneous rock that forms during explosive volcanic eruptions. It is used as aggregate in lightweight concrete, as landscaping aggregate, and as an abrasive in a variety of industrial and consumer products. Pumice has several advantages over other filtration media such as expanded clay, anthracite, sand, and sintered pfa. Comparison tests done between deep bed sand and pumice filters for treating water found pumice to be superior in turbidity removal performance and head loss. Pumice is a very light weight, porous and abrasive material and it has been used for centuries in the construction and beauty industry as well as in early medicine. It is also used as an abrasive. There is high demand for pumice, particularly for water filtration, chemical spill containment, cement manufacturing, horticulture and increasingly for the pet industry.

]]>Water Treatment Garnet solves a major filtration problem.
A properly designed multi-media filter system contains filter media of large grains on top and small grains on the bottom of the filter and provides superior performance even after many backwashings.
The solid substances getting into the entire filter bed result in increased solids storage, longer filter runs and higher filtration rates.
This stable condition of large grains above finer one is achieved by the use of filter material of different size and specific gravities.
Garnet has a high specific gravity provides unique filter design.
Garnet, in combination with other filter media, provides higher flow rates, higher loading and better filtration.
The high hardness of Garnet reduce attrition and extends the life time of the filter bed and provides for years of reliable service.
Garnet is an excellent support bed for other high density medias.
Garnet is used in sand filters for Water Filtration with other water treatment filtration media products such as Gravel, Anthracite, Silica Sand, Birm, Pumice and Activated Carbon.
Our filter garnet is a high hardness, high density granular filter media.
It can be used extremely effectively as the lower layer in a dual media filter system – in conjunction with sand, gravel and occasionally filter coal.
With characteristics such as high specific gravity as well as chemical and abrasion resistance, our filter garnet is ideal for water filtration.

]]>Industrial Raw Silica Flour industrial minerals is a very finely divided, highly purified form of crystalline silica that consists of particles of up to 150 μm in diameter. Crystalline silica is milled to a fine powder by crushing, grinding, or ball milling to produce the flour. Silica flour is used as an abrasive additive in soaps, skin care products, toothpastes, and paints, and as a filler in construction chemicals and pharmaceuticals. It also is used in foundry work and in glass, ceramic, porcelain, tile, and clay production.
Silica Flour is used as Industrial Raw Materials with other industrial raw material products such as Calcium Carbonate, Limestone, Aggregate, Quicklime, Talc, Volcanic Rock and Abrasives. Products containing silica have been used for thousands of years to build and make things – and it is a key ingredient in many products we use every day. Silica flour is used to form a stronger and less permeable cement, especially for high-temperature applications. The production of sand fillers is simple because it includes, at most, only washing and classification into grades differing in grain size. Because sand has a negligible degree of porosity it has an extremely low specific surface area. Ground silica sand is produced in a similar manner, except that pulverizing is included. Ground silica can easily be distinguished under the microscope because it has irregular grains.

Filtration and Water Production:
Industrial sand is used in the filtration of drinking water, the processing of wastewater, and the production of water from wells.
Uniform grain shapes and grain size distributions produce efficient filtration bed operation in removal of contaminants in both potable water and wastewater.
Chemically inert, silica will not degrade or react when it comes in contact with acids, contaminants, volatile organics, or solvents.
Silica gravel is used as packing material in deep-water wells to increase yield from the aquifer
by expanding the permeable zone around the well screen and preventing the infiltration of fine particles from the formation.

]]>Industrial Raw Materials are used is used for buffing, sanding, grinding, or polishing with other products such as Silica Flour, Limestone, Aggregate, Quicklime, Talc, Volcanic Rock and Calcium Carbonate. An abrasive is a material, often a mineral, that is used to shape or finish a workpiece through rubbing which leads to part of the workpiece being worn away by friction. While finishing a material often means polishing it to gain a smooth, reflective surface, the process can also involve roughening as in satin, matte or beaded finishes.As long as the abrasive itself is harder than the material you’re trying to finish, an abrasive will be a very effective way of honing down any material to prepare it for use. Industrial Raw Materials Abrasives consist of minerals that can be either naturally-occurring or synthetic, such as calcite, emery, pumice, sandstone, garnet, borazon, ceramic, steel abrasive, and silicon carbide. When used for industrial applications such as mining, construction, railroad, and wholesale/retail operations, usage falls into several different categories: bonded, coated and others. A grinding wheel is a good example of a bonded abrasive, operated at very high speed to finish any material which is pressed against it. Sandpaper is the most commonly used coated abrasive, and is affixed to a backing material, such as paper or metal.
While sandblasting a stream of Industrial Raw Materials Abrasives is thrown out on the surface of the workpiece to make it smooth or to remove the contaminants from the surface. Apart from this, these are used in automotive paints. Calcium carbonate is also an Abrasive that is used in toothpaste. In this particular application, hardness of the Abrasive is more than that of the contaminating agent but less than that of the tooth enamel. This helps in removing the bacterial plague without damaging the tooth enamel. Abrasives are also used in the processing of jewelry pieces.

]]>Hydrated Lime Mineral also known as Calcium Hydroxide, is an inorganic compound which is formed when Calcium Oxide is combined with water and is used in tanning and agriculture. Hydrated lime is also used in the treatment of drinking water. Hydrated Lime is used as Industrial Raw Materials with other industrial raw material products such as Silica Flour, Limestone, Aggregate, Quicklime, Talc, Volcanic Rock and Abrasives.
Hydrated lime is essential to the production of sugar from both sugar cane and sugar beets. It is also used to purify sugar from other sources, such as maple or sorghum, although these are produced in much smaller quantities. Lime also serves a myriad of uses in the food industry. Alkali plants with access to natural soda ash use the “lime-soda process” to manufacture caustic soda (sodium hydroxide). Sodium carbonate (soda ash) reacts with lime slurry to form caustic soda and precipitated calcium carbonate as co-products. Calcium carbide, the oldest source of acetylene, is formed by mixing quicklime and coke. Lime is used in the two major processes to manufacture magnesia (magnesium oxides): the seawater process and production from brines. Calcium hypochlorite bleaches are produced by reacting lime with chlorine. Lime can be combined with certain additives to produce other metals and is also a key ingredient in mortar and plaster in lime slurry form. As an additive in asphalt, lime improves its cohesion, reduces stripping, and retards the aging process.
Besides being a significant flocculant in water and sewage treatment, hydrated lime is also used in the preparation of ammonia gas, and is used in the paper industry. Aqueous solutions of hydrated lime are called limewater; medium strength bases that react with acids that can attack some metals such as aluminum while protecting other metals from corrosion such as iron and steel by passivation of their surfaces. Hydrated lime adopts a polymeric structure, as do all metal hydroxides. It is produced commercially by treating lime with water.
