Industrial Sands
Sands for Water Filtration
Sand filters are used to treat drinking water in many developed and well as developing countries and they work by using a complex biological film that grows naturally on the surface of the sand. The sand itself does not perform any filtration function but acts as a substrate. However the grading of the sand in filter beds is the most crucial element of any filter plant, which will determine the functionality and longevity of the plant. They are often the preferred technology in many developing countries because of their low energy requirements and robust performance. Following are some of standard ranges of Filter Media Sand & Gravel we are generally producing:
