  • Rapid Sand Filtration SSWMFind tools for sustainable

    Rapid sand filters evolved at the end of the 19th century in the United States and quickly gained popularity. By the 1920s they were widely used as a major water purification method since necessary facilities required less land area compared to slow sand filters.Today a combination of flocculation and coagulation sedimentation filtration and disinfection (e.g. chlorination ozonation) is

    Filtration is a process that removes particles from suspension in water. Removal takes place by a number of mechanisms that include straining flocculation sedimentation and surface capture. Filters can be categorised by the main method of capture i.e. exclusion of particles at the surface of the filter media i.e. straining or deposition within the media i.e. in-depth
