Abstract:
The base RO process starts with raw water (Brackish Water) pumped from the submersible then the water is dosed with chlorine which kills bacteria and other microbes. After that multigrade sand filter comes to process in which contaminants are captured in the sand bed of filter. After this Sodium Meta Bi Sulphite (SMBS) dosing removes the excess chlorine. The activated carbon filter then removes organic particles through absorption. The antiscalent dosing further removes calcium, magnesium salts to prevent scaling of membrane. The micro cartridge filter further removes the bacteria etc having range of filtration 0.1 to 10 μm. Then the water is passed through the high pressure pump which is reciprocating. This increases the pressure and water is passed to RO Membrane which is the heart of the system. The membrane separates the water and salt. The pure water is taken out from the outlet of Membrane
