Iron Remover Followed by Water Softener

Iron Remover: Multi grade filter is quite straight forward. In a multi grade filter or pressure iron removal filter, water is passed through multi layers of filter media consisting graded mno2, pebbles and KT layers. The contaminants in the water are captured in the media bed and filtered water passes into the discharge manifold at the bottom of the tanks. The next and last step is backwashing, a process of effectively removal of captured contaminants from the media bed. After back-washing the filter is rinsed with raw water and after the required quality of water is achieved the filter is put back into service. Water Softener: Most water softeners on the market are ion exchange systems. In these systems, hardness ions (calcium and magnesium) are exchanged for salt (sodium or potassium) ions. The exchange takes place within the resin tank of the water softener. When water flows through the tank it comes in contact with small resin beads that are covered with salt ions. As water flows through the resin beads, hardness ions trade places with salt ions, hence the higher salt content in softened water.
