Login. High salt content . Disadvantages of Water Softeners: Increased water consumption - According to the Environmental Protection Agency (EPA), the ion exchange process employed by a salt-based water softener uses approximately 25 gallons of water per day. Zeolite process. Finally, when water is stabilized using recarbonation at the end of the lime softening process, corrosion in the distribution system is avoided. 2) It produces water of very low hardness (upto 2 ppm ) . Based on their function, advantages and disadvantages, we compare the water softeners with each other. Advantages And Disadvantages Of Water: . Permutit is the synthetic zeolite that is most used in water softening and its chemical formula is Na 2 O, Al 2 O 3, nSiO 2, xH 2 O. Ion exchanger Also known as the classic water softener. Addition Of Sodium. A softener can waste up to 120 gallons of water for every 1,000 delivered, which can significantly increase you water bill. Raw material must be liberated from suspended polluting influences. The water ought not be turbid. A water softener does not remove lead and other metals, or chlorine taste/odor compounds or by-products. 1. 2. The end products may be too soft for some people! The exchange of the hard minerals for sodium adds almost 7.5 milligrams per quart for one GPG of the hardness removed. Therefore, hard water can be converted into soft water by making use of ion-exchange resins. Process For softening of water by zeolite process,hard water is percolated at a specified rate through a bed of zeolite, kept in a cylinder. The process has some disadvantages in that there are substances occuring in some water (such as organic matter or Fe 3+ ions) which can foul the resin, but in general the advantages of the process . We face a problem where our clarifier is accumulated with sludge cake (2 to 3ft) on the surface of water. if this process is combined with sedimentation with coagulation, lesser amounts of coagulants shall be needed.
