Raw water is initially dosed with chlorine. This takes care of the organic matter to some extent. Raw water is then passed through Multi Media Filter with the help of Feed pump of suitable capacity to remove suspended impurities. This filer unit gives the coarse filtration. Filtered water is then passed through Activated Carbon Filter to remove excess chlorine (dechlorination), odour, and turbidity due to colloidal suspended impurities and organic impurities. De chlorinated water is then dosed with antiscalant dosing system. The water is further passed through 5 micron cartridge filter to remove micron particles to avoid clogging of the Reverse Osmosis membrane. Reverse Osmosis unit is the heart of the treatment scheme. It will reduce the Dissolved Salts from the raw water up to the remarkable level. A lot of bacteria are also removed in this process. The treated water from Reverse Osmosis unit will be passed through Ultraviolet Sterilisation to ensure complete bacteria free pure water.
