Discuss zeolite process with the help of diagram, chemical ... 3) Zeolites of iron and manganese cannot be easily regenerated by passing NaCl solution. Hence iron and manganese impurities in the water to be treated must be minimum. Advantages 1) Water of about less than 15 ppm is obtained. 2) The process automatically adjusts for different hardness of incoming water. 3) Water obtained is quiet clear. Difference Between Zeolite and Ion Exchange Process ... The key difference between zeolite and ion exchange process is that the zeolite process uses the mineral zeolite as the exchanging resin for cations in the hard water whereas the ion exchange process may include several different resins for the ion exchange. Furthermore, the zeolite process is a form of ion exchange process of softening hard water. Zeolite Process of Water Softening Dr. Rajdeep Deb Ø This process does not involve any type of precipitation, thus, no problem of sludge formation occurs. Demerits of Zeolite Process: Ø The outgoing water (treated water) contains more sodium salts. Ø This method only replaces Ca 2 and Mg 2 ions by Na ions. Ø High turbidity water cannot be softened efficiently by zeolite process. zeolite process for water softening | Hard and Soft Water Zeolite process for water softening Zeolite process for water softening has become a commercial success for the reason that zeolite can be easily regenerated.
