WATER PROCESS DESCRIPTION

Raw water is chlorinated with the help of dosing pump, Sodium Hypo chloride is dosed in raw water before it is taken into the raw water tank/s. (Storage tanks are considered in your scope and should be of 20 M3 to 50 M3 capacity). Storing of water into this tank will give retention period for water and thus chlorine will effectively oxidize the organic impurities (kill bacteria and virus).  This chlorinated water is passed through Multi Media Filter with the help of Feed pump of suitable capacity to remove suspended impurities. This filter unit gives the coarse filtration. Filtered water is then passed through Activated Carbon Filter to remove excess chlorine (de-chlorination), odour, colour and turbidity due to colloidal suspended impurities and organic impurities.  De chlorinated water is then dosed with Anti Scalent Solution to avoid scale formation on the membrane. This water is further passed through 10-micron Bag Filter Followed by 5 Micron Cartridge filter to remove micron particles to avoid clogging of the RO membrane and to improve the silt density index. This water is further dosed with SMBS solution to remove residual chlorine from Water. RO Unit is complete with High Pressure Pump, Membranes with Pressure tubes, Electrical control panel and wet panel, piping with valves and all the required accessories viz., pressure switch, solenoid valve etc. Reverse Osmosis unit will reduce the dissolved Salts up to 95% of the in feed TDS. RO treated water is either adjusted for TDS by blending Filtered water passed through 0.2 Micron Cartridge Filter followed by UV OR dosed with Mineral. pH is also adjusted in case of pH below the limit to raise to 7.5.  Treated water from RO unit will be stored into SS tank of 2000 Lts capacity.  This treated water is then passed through 0.2 micron cartridge filter before it is taken for the filling. Ozonator unit producing ozone gas is installed in series at the outlet of UV System to provide residual effect of ozone to the water.
