Quartz sand filter material is a water treatment filter material made of natural quartz ore through crushing, washing, screening, drying and re screening. There are two types of quartz sand filter media: one is general quartz sand; the other is refined acid washing sand. Quartz sand filter material has the characteristics of high hardness, good corrosion resistance, high relative density, high mechanical strength, strong interception function and long service life. It is an ideal material for chemical water treatment. It is the most widely used water purification material in water treatment industry.

Quartz sand filter material has filtering effect, just as water penetrates into the ground with the aid of sand and gravel, blocking suspended solids in water, mainly those fine suspended solids.

1. The sum of crushing rate and wear loss of quartz sand filter material should not be 1.5% of dry (percentage by mass, the same below);

2. The relative density of quartz sand filter material should not be lower than 2.55g/cm3. Except those with special requirements for relative density in use;

3. Quartz sand filter material should be free of visible soil, mica and organic impurities. The water leaching solution of the filter material does not contain toxic substances, and the mud content is not more than 1%. The content of light substance with relative density less than 2G / cm3 should not exceed 0.2%;

4. The ignition loss of quartz sand filter material is not more than 0.7%, and the solubility of hydrochloric acid is not more than 3.5%.

It is made of natural quartz ore by crushing, screening, washing and other processes. The appearance is polygonal, spherical, pure white, with high mechanical strength, strong river regulation function, acid and alkali resistance.
