Filtration of unresolved substances contained in water

Sand filters are made up of a vessel and the necessary supply and drain pipes. Filters must be flushed back to remove the accumulated material. The grain size of the sand is adapted for the materials to be filtered. The drinking water quality can be improved with special sands. Bacteria and nearly all viruses can be removed by the sand filters.

Applications: - Pre-treatment of cooling water
