How Do Industrial Water Softeners Work?

Industrial water softeners utilize hydraulic or pneumatic valves, which feature a co-current regeneration sequence based upon elementary principles of iron exchange. Initially, strong acid cation resin in the sodium (Na +1) form is placed into service. During the sodium cation exchange industrial water softening process, sodium ions are exchanged for undesirable quantities of calcium (Ca +2), magnesium (Mg +2), and iron (Fe +2). Sodium ions already present in the water being softened pass through the process unchanged. Upon exhaustion of the resin (as indicated by unacceptable hardness leakage), a regeneration sequence involving sodium chloride (NaCl) is utilized. The generation sequence reverses the above process and converts the strong acid cation resin back to the sodium form for the subsequent water softening cycle.

Industrial water softening capacities range from 20,000 to 30,000 grains per cubic foot depending upon the total dissolved solids content of the water, the effluent water quality desired, and the amount of sodium chloride regenerant used. It should be noted that although the water is softened, the total dissolved solids content remains unchanged. Further, the effluent contains the same amount of anions as the raw water. The equipment is co-currently operated (down-flow exhausted; down-flow regenerated). All industrial water softening models have five distinct cycles of operation:

• Service – softening process; down-flow
• Backwash – hydraulic cleaning; up-flow
• Brine inject – restores resin to sodium form; down-flow
• Slow rinse – displaces residual brine; down-flow
• Fast flush – prepares softening resin for service cycle; down-flow.
