We, ION Water Machineries, Manufacturer and supplier of R.O. Plant and other Iron removing andother water treatment equipment since 1967.Reverse Osmosis is a separation process, in which a solvent, water in this case, is permitted to pass through a semi permeable membrane, leaving behind the dissolved solids called Cations and Anions. Depending on the mobility of these ions, the water portion passes through the membrane and very low amount of salts will pass through the membrane. Thus the filter water has about 10% TDS. This process will remove Bacteria, Virus, Protozoa, and reduce the harmful chemicals namely Fluorides, Nitrates, Pesticides, Lead, Mercury, Arsenic etc. During Reverse Osmosis Process, there is a continuous rejection of water with concentrated salt content and this will be coming out from the RO catridge, This is very important for membrane cleaning and it also prevents membrane for choking due to scaling of Calcium and Magnesium. Hence, the water flow is adjusted in such a way that purified and rejected water is maintained at 1:3 ratio
