Sand filters for the removal of undissolved solids
Sand or gravel filters remove undissolved solids (particles) from water or process fluids. Sand filters consist of a container with a sand/gravel bed, which serves as the filter material. The water is pushed through the filter bed. Dirt particles are trapped in the filter material. Sand filters are used, for instance, for pre-filtration of well water and surface water or for the filtration of cooling water.
