Conventional Water Treatment: Coagulation and Filtration

10/01/· Rapid sand filtration is a physical process that removes suspended solids from the water. Rapid sand filtration is much more common than flow sand filtration, because rapid sand filters have fairly high flow rates and require relatively little space to operate. In fact, during rapid sand filtration, the water flows at a rate up to 20 metres per

Biosand FilterThe Biosand filter

Rapid sand filtration removes particles over a substantial depth within the sand bed. In contrast, slow sand filters can remove particles that are smaller than the spaces between sand grains. Slow sand filters contain very fine sand and usually function without chemical pretreatment, such as chlorination or flocculation. The low filtration rate causes long detention times of the water above

Filtration, usually rapid sand filtration, is then employed for further "polishing", i.e. to get the turbidity to lower than 0.5 NTU (as required by legislation). Rapid sand filtration after prior sedimentation is the most common configuration worldwide. Increasingly, direct filtration is being employed where the turbidity of the raw water is not high. Slow sand filtration is not very
