H2K industrial sand filters are designed to remove larger suspended solids 50-100 microns using a single size of filtration media. The coarseness of the filtration process can be determined by adjusting the size of the filter sand. The effective size of each granule of sand typically varies from 0.35mm 1.2mm.

Rapid Sand Filtration The water above the filter provides the hydraulic pressure head for the process. The filter medium is above a larger gravel rock or other media for support. Below the rock is usually an underdrain support of some type. The water flows through the filter and support media exiting from a

Jul 26 2014 The filter sand used in rapid sand filters is prepared from stock sand specifically for the purpose. Most rapid sand filters contain 60 to 75 cm thickness of sand but some newer filters are deeper. The sand used as filter media in RSF is generally of effective size of 0.4 to 0.7 mm and uniformity coefficient of 1.3 to 1.7.
