Jan 10, 2017Rapid 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
