Sand Filter

Pressure sand filters (PSF) are used in many industrial applications including RO & DM plant and often are popularly termed rapid sand bed filters.PSF consists of a pressure vessel that is normally vertical or horizontal, in rare occasions, depending on the layout of the plant.

The filter vessels are generally of welded mild steel construction lined with rubber/epoxy. A minimum of 50% freeboard is provided over the filtering bed depth to enable efficient backwash. Water from Feed water will be pumped to the sand systems which provide to remove suspended solids (TSS) and solids in the raw water.
