Industrial Mixed Bed
Industries like Pharmaceuticals, Medium and High Pressure Boilers, Power generation by Steam, Turbines, Electronics industries are required extremely pure quality of water.The
MIXED BED is the answer where the Two Bed DM plant is used prior to Mixed Bed.
The mixed bed mixture of Cation and Anion resins form infinite numbers of demineralising
stages through which DM water passing and thus removing the traces of minerals i.e.slippage (<5 ppm) from DM plant. By this method demineralised water of extremely pure quality is achived, which cannot be otherwide obtained by any commercial production methods.
The mixed resins are separated by means of backwash, as the anion resin's specific gravity is lower than Cation resin. The separated bed is then regenerated with Acid and alkali solution, which passes through the Cation and Anion bed,via specially designed distribution and collecting systems. After the regeneration with the help of compressed Air both Cation and Anion resins are re-mixed. |
