Applications of sand filters

Sand filtration is intended for pre-purification and post-purification of surface and river water, industrial water, and cooling water. Filters whose filter medium consists of sand are also used in coagulation filtration. Sand filtration is widely used in all water management operations.

It is also used in apartment buildings and domestic wells to post-purify drinking water. Sand filtration is most widely used in the treatment of drinking water and in the energy industry, as well as in industrial fields and the food industry, where filtration treats the input water needed for production and the output wastewater.
