REVERSE OSOMOSIS: ADVANTAGES AND DISADVANTAGES
ADVANTAGES of Reverse Osmosis: This method has greater advantages of removing ionic, non-ionic, colloidal and high-molecular weight organic matter. The lifetime of the membrane is quite high (2 years). The membrane can be replaced within a few minutes. It provides nearly uninterrupted water supply. Due to low capital cost, low operating cost and high reliability, this method is superior than other methods. DISADVANTAGES of Reverse Osmosis: Reverse Osmosis plays a major role in providing portable water defined by the WHO criterion of < 500 ppm of total dissolved solids (TDS). Extremely high-quality water required for nuclear power plants can be made from sea water by the reverse-osmosis process. Sugar concentration, waste-water recovery and beverage uses are a few of the current popular applications of the reverse-osmosis process.
