Water Softening

Water Softening (Ion Exchange) is a very efficient process in which the hardness cations (calcium and magnesium) are removed from the water. Passing the water through a bed of synthetic polymer beads, which have been developed with an affinity for these cations, accomplishes this. The resin beads in the regenerated state have a high concentration of sodium ions. These sodium ions have a relatively low electrical potential compared to that of calcium and magnesium, ions. This means ions with a greater potential or charge can easily replace them. When the inlet water flows through a cation resin bed, the calcium and magnesium ions bond to the resin beads, and the beads release sodium ions in exchange.

The resins must be regenerated when water quality becomes substandard as the total amount of water softened or hardness monitoring determines. Regeneration is an ion exchange process wherein the calcium and magnesium ions on the resin beads are exchanged for sodium ions. This ion exchange is achieved by flushing the system with a brine solution that contains a high concentration of sodium ions.

Progressive offers a complete line of Industrial Ion Exchange Softeneing products to meet the needs of each individual client. Ion Exchange options include Softening, Two Bed, Mixed Bed, Packed Bed (to 200GPM/train), Ion specific removal systems (i.e. Nitrate, Arsenic, etc.) and non-regenerable units. All systems are custom design/build equipment. In every case, the customer's requirements and preferences are considered prior to any design.
