Uses:

Quartz sand is used in wastewater treatment, water from drilled wells, domestic water filters ... Effectively, filter suspended particles of small particle size that cannot precipitate when deposited naturally. During the filtration process, on the surface of sand will create a filter layer to support the filtration process, especially when Fe (OH) 3 precipitates on the sand surface will help adsorb arsenic when water sources are at risk of arsenic contamination. . Quartz sand is a very good agent in keeping the high viscosity cotton precipitate very difficult to separate and filter.
