Rapid Sand Filters Water Treatment Waste Water

The Rapid Sand Filter (RSF) water treatment equipment differs from the Slow Sand Filter water treatment equipment in a variety of ways, the most important of which are the much greater filtration rate and the ability to clean automatically using back washing. The mechanism of particle removal also differs. Rapid sand Water filter does not use biological filtration and depends primarily on

Rapid sand filtration is a highly effective method to remove turbidity if it is correctly applied (BRIKKE & BREDERO 2003). Equally, solids formed during pretreatment, i.e. coagulationflocculation, are filtered.A welloperated RSF reduces turbidity to less than 1 NTN and often less than 0.1 NTU (WHO 1996).
