What Is PSF ?
Sand Filters are used for water purification. There are three main types :-
Rapid (gravity) sand filters
Upflow sand filters
Slow sand filters
All three methods are used extensively in the water industry throughout the world. The first two require the use of flocculation chemicals to work effectively whilst slow sand filters can produce very high quality water free from pathogens, taste and o dour without the need for chemical aids. Sand filters are occasionally used in the treatment of sewage as a final polishing stage (see Sewage treatment). In these filters the sand traps residual suspended material and bacteria and provides a physical matrix for bacterial decomposition of nitrogenous material, including ammonia and nitrates, into nitrogen gas.
