Sand filtration is used for the removal of suspended matter, as well as floating and sinkable particles. The wastewater flows vertically through a fine bed of sand and/or gravel. Particles are removed by way of absorption or physical encapsulation. If there is excessive pressure loss on the filter, it must be rinsed Industrial Filtration Systems are used in many industries including food processing, pharmaceuticals, chemical manufacturing, water treatment, mining, power generation, pulp & paper, oil & gas, and more. They can be used as stand alone systems or as part of an integrated filtration system.
