Rapid sand filtration, in contrast to slow sand filtration, is a purely physical treatment process. As the water flows through several layers of coarsegrained sand and gravel, relatively large particles are held back safely (DIJK & OOMEN 1978). However, RSFs never provide safe drinking water without adequate pretreatment and final disinfection.
