石英砂过滤器适用条件及安装运行要点(国外英文资料) Application of quartz sand filter and installation running points One, product introduction: The quartz sand filter contains a selection of pickling quartz sand. When the water from flowing through the filter layer, the water of solid suspended material in the upper filter material to form small hole, by mechanical impedance function by filter material surface layer closure. In addition, due to the filter material to each other closely arranged, the suspended particles in the water flows through the winding channel filter material, there are more opportunities and time to contact with the filter material surface collide with each other and, as a result, the suspended solids in the water on the surface of the particles that filter material and mutual adhesion, floc further purified water. Filter backwashing regularly can realize regeneration, the operation of the filter and backwashing - are washing - operation and other related process through the switch valve to complete. Second, product characteristics: Quartz sand filter has simple structure, convenient operation and maintenance, and can realize automatic control, high filtration efficiency, small resistance, processing flow, fewer back flush. Widely used in pure water, food, drinking water, mineral water and electronics, printing and dyeing, paper making, chemical industry, water quality of pretreatment and filtering after secondary treatment of industrial wastewater. It is also used for the deep filtration of water recycling system, swimming pool circulating water treatment system. The suspended objects in industrial wastewater are also well removed. This is a steel pressure filter, such equipment can remove suspended matter in raw water, mechanical impurity, residual chlorine and chromaticity, according to the different filter material, mechanical filter are divided into single, double, three layers of filter material and fine sand filter; The filter of quartz sand filter is usually
