I plant the use of high-quality natural quartz ore as raw material, the mechanical crushing, rolling rolling, washing screening, drying and screening, vibration and a series of new production process, the effective protection of the natural structure of quartz, thus extending the filter life cycle. The utility model has the advantages of fast filtering speed, good filtering effect, stable effluent quality, no blockage and no agglomeration. The sand than the use of long cycle (1-2 cycle).
Quartz sand filter product details:
Application scope
Refined quartz sand filter material for drinking water filtration and other water purification treatment. More suitable for dry oil, chemical, mining, metallurgy, thermal power, paper making, printing and dyeing, leather, food and other production water treatment and recycling of water, as well as the recycling of sewage.
Technical requirements of quartz sand filter media
1) mechanical strength, crushing rate and wear rate should not be greater than 1.5% (percentage by weight).
2) chemical property is stable, does not contain visible clay, mica and organic impurities, the water extract of the filter material does not contain toxic and harmful substances.
3) the density of quartz sand should not be less than 2.55g/cm3. (except for special requirements for density in use).
4) the weight loss should not be greater than 0.7%, and the hydrochloric acid soluble rate should not be greater than 1.5%.
5) the content of the light substance shall not be greater than 1%, and the content of light matter less than 2g/cm3 shall not be greater than 0.2%.
6) the particle size distribution is reasonable, and the appearance of the crystal is a multi angle monologue. Single or double layer filter material particle size range, generally 0.5-1.2mm. Three layer filter material particle size range, generally 0.5-0.8mm.
7) the particle size range is less than the lower limit of the size of the weight of not more than 3% by weight, larger than the upper limit of the size of not more than 2%.
8) the particle size range of quartz gravel bearing layer is generally 2-4, 4-8, 8-16, 16-32 and 32-64mm.
