Quartz gravel sand filter is the most common filter materials, refined quartz sand filter widely used, the use of a range can be used for drinking water and water for industrial production as well as a variety of pools shaped ordinary rapid filter and sewage filter , the water purification mechanical filter. The quartz sand Description: My company uses natural quality quartz deposits as raw material, by mechanical crushing, scroll crushed, washed screening, drying sieve, vibration grading series production of new technology, the effective protection of natural quartz stone structure, which results in longer the use of the filter cycle. Quartz sand filter fast, filter effects, water quality and stability, no blocking, no caking. Use the sand on a long cycle (1-2 cycles). The scope of the use of quartz sand: refined quartz sand filter for drinking water and other water purification process. Quartz sand filter is more suitable for the petroleum, chemical, mining, metallurgy, thermal power, paper making, printing and dyeing, tanning, food production and water pre-treatment and recycling of water treatment and recycling of wastewater. Quartz sand technical requirements: ⑴ and mechanical strength, crushing rate and wear rate should not exceed 1.5% (percentage by weight). (2) chemically stable, free from visible dirt, mica and organic impurities, filter the aqueous extract contain toxic and hazardous substances. ⑶ quartz sand density should not be less than 2.55g/m3. (Using special requirements except density). ⑷ quartz sand burning weight loss should not exceed 0.7%, ⑸ clay content should not be more than 1%, the light material density is less than 2g/cm3 content should not be greater than 0.2% (ministerial standards) . ⑹ particle size gradation and the appearance of multi-angular monologue shiny crystal. A particle size range of the single or double filter, typically 0.5-1.2mm. A particle size range of the three-layer filter, typically 0.5-0.8mm. ⑺ particle size range less than the specified lower limit of the particle size of not more than 3% by weight, greater than the prescribed maximum particle size of not more than 2%. ⑻ support layer of quartz gravel particle size range, generally 2-4,4-8,8-16,16-32 and 32-64mm (Buban standard).
