Quartz sand filter is environmental protection field, deep treatment of sewage in qing dynasty the earliest, the most common application. Quartz sand filter to remove the water is the most effective means of suspended solids, is deep treatment of wastewater, sewage reuse and water treatment in the important unit, its effect is will the water has flocculation pollutants further removes it through the filter material, the interception and adsorption effect settlement and, to the purpose of water purification. Quartz sand filter using quartz sand as the filter medium. The filter material has high strength, long life, water treatment, outlet water quality is stable and reliable, quartz sand the obvious advantages of the main functions are suspended in the water to remove, colloid, sediment, rust. The pump pressure, make the raw water through the filter medium, remove the suspended in the water, so as to achieve the purpose of the filtration. Features: simple structure, convenient operation and maintenance, operation can achieve automatic control, filtration efficiency high, small resistance, processing flow, fewer recoil. Widely used in pure water, food beverage water, mineral water and electronic, printing, dyeing, papermaking, chemical industry the pretreatment of the water quality and industrial sewage 2 level process after filter. Also used in water reuse system, swimming pool seawater treatment system depth filtration. for the industrial waste material also has good effect to remove. this kind of equipment is steel pressure type filter, can remove the raw material, the mechanical impurities and residual chlorine and chromaticity, press filter material, different mechanical filter are divided into single, double, three layer filter material and fine sand filter; Quartz sand filter material generally as a single layer quartz sand, particle size of 0.8 ~ 1.2 mm, filter height is 0.9 ~ 1.2 m usually. According to the structure and divided into the single flow, double river, vertical, horizontal; According to the inside surface corrosion request, and divided into line with rubber type and the rubber lining type.
