Ro Plants Spares

Most reverse osmosis membranes are formed from hollow fibre or thin film composite sheets with the membrane allowing passage of pure water and rejecting the dissolved solids contained in the water.
The traditional way to prevent this was to "de-alkalise" the water using sulphuric acid to prevent calcium carbonate precipitation. However the acid is hazardous increases the sulphates and increases the corrosivity of the water on both sides of the membrane. Reducing the recovery rate of the reverse osmosis plant eliminated calcium sulphate but this reduces the efficiency of the plant and hence increases costs.
