Multigrade Filters

Water from Natural Sources contains suspended colloid. The conventional sand filter, multi grade filters are used to remove suspended matters in raw water. The activated carbon filters are used for removal of colour, order and free chlorine content of water. In effect, raw water with micron size un-dissolved matters should be passed through Micron Cartridge Filter.
The water filtration process involves the flow of water via a granular bed of filtring sand or another suitable media. The water to be filtered flows at a low speed. The media (the filter) retains most of the solid matters and let the water pass through it. The process of filtration is generally repeated to ensure sufficient removal of unwanted particles in the water.
