WebbThe mechanisms of removal in slow sand filtration include entrapment, adsorption, biological flocculation, and biological degradation. In fact, one of the reasons for the very low hydraulic loading rate of slow sand filter is to allow aerobic conditions within the first inch or two of the sand filter depth. Webbstudied in literature: bioswales, trickling filters, constructed wetlands and natural wetlands, treatment ponds, riparian zones, bank filtration, and slow sand filtration. An effective filter is the result of biological degradation and physical/chemical processes such as adsorption and straining of contaminants on the biofilter media.
