Rapid sand filter

Definitions of rapid and slow sand filtration. Rapid sand filtration is mainly used in combination with other water purification methods. The main distinction from slow sand filtration is the fact that biological filtration is not part of the purification process in rapid filtration.

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

Instead of slow sand filtration, rapid sand filtration was now applied. Filter capacity was improved by cleaning it with powerful jet steam. Subsequently, Dr. Fuller found that rapid sand filtration worked much better when it was preceded by coagulation and sedimentation techniques.

A commonly used process in water treatment for the removal of discrete particles and particle flocs. It is often used in concert with other processes (coagulation and flocculation), but for waters with low turbidity it may be the sole process for particle removal.

63 The general features of slow and rapid filters are summarised in Table 6.1. Slow sand filters are conventionally operated at a filtration rate in the range 0.1-0.2 m 3m-2h-1 (approximately 0.029 mm s-1) and rely to great extent on the formation of a biological layer or 'Schmutzdecke' for their cleansing
