Treatment sand is produced in accordance with TS EN 12904 standards after washing and screening processes from natural quartz sands and classified in desired sizes. Quartz sands used as treatment sands do not dissolve in acid experiments and do not lose mass.
Quartz sands used in drinking water treatment are sand treatment sand created with some elements and chemicals. Harmful microorganisms, deposits, bacteria and harmful particles in the water can be separated with purification sand.
Treatment sands are mainly used in drinking water treatment plants, wastewater treatment plants, boiler filters and swimming pools. Quartz Treatment sands must comply with TS EN 12904 standards. When quality and right products are selected, the quality of drinking water increases accordingly.
Quartz filter sands used for filtering have high wear resistance. For this reason, it offers long-term solutions in filtration.
There are fast and slow sand filter systems in drinking water treatment plants. Fast sand filters generally work with nozzle and backwash system in the range of 0,800-1,200 mm filter sand. In slow sand filters, bedding is done with 15-25 mm gravel and 5-15 mm gravel. 3-5 mm and 1-3 mm gravel are placed on it. The top layer is placed in the range of 0,300-0,500 mm, about 1 meter of high treatment sand. Water flow rate is low in slow filters. Slow or fast sand filter choices are made according to the chemical structure and pollution rate of the water. Sometimes the top layer treatment sand dimensions can be in the range of 0.400-0.800 mm and 0.600-1.0 mm or in the specified alternative size range.
Purification of Sand Function:
Sand filters are highly efficient units designed to remove insoluble, various sizes of particles, suspended solids in the water. Therefore, the main unit that must be in a general treatment system is the sand filter.
How to Treat with Purification Sand? :
Fully automatic sand filters have a structure consisting of different sizes of Quartz and anthracite layers in polyethylene or steel tanks. Thanks to this structure, the filtration is provided not only on the upper surface of the filter bed, but on all layers, making it more efficient.
