The Continuous Sand Filter is an upflow, deep bed, granular media filter used with continuous backwash in the removal of suspended and colloidal solids. The filter media is cleaned during the filtration operation by a simple internal washing system that does not require backwash pumps or storage tanks. This ensure uninterrupted operation without stopping for backwash and the absence of backwash pumps bring the low energy consumption.
We provide professional Continuous Sand Filter that easy to operate and economical sand filter for continuous cleaning of sand to achieve efficient effluent cleaning compared to conventional filter.
