Addressing the source of the problem is often less costly in the long run than installing and maintaining a water system. For more information
The EPA first published a Water Treatment Manual on Disinfection in 1998. This manual has been authority for the treatment of drinking water.and a sanitary authority shallhave regard to such criteria other domestic type purposes, regardless of its origin and whether it is supplied from a distribution network,.

Filtration 2. TYPES OF FILTERS. Several types of filters are used for water treatment. Early slow sand filters typically have filter rates of 0.05 gpm/ft2 of surface area and require large filter areas. The top several inches of the sand has to be removed regularly--usually by hand--due to the mass of growing material.
remove organic contaminants from potable water. The chemical processes involved in potable water treatment include oxidation15, coagulation16 and disinfection17. The physical processes include flocculation18, sedi- mentation19, filtration20, adsorption21, and disinfection using ultraviolet light. The types of processes

The most widely applied water treatment process is a combination of some or all of the following: coagulation, flocculation and sedimentation, plus filtration, and has been used routinely for water treatment since the early
