The evolution of water softeners Corpus Christi continued beyond fully automatic units with the introduction of demand-initiated regeneration (DIR) water softeners. In these units, the water softener is equipped with a flowmeter, which automatically initiates the regeneration process after a predetermined volume of water has been softened. Alternately, DIR units can be based on hardness sensors, which monitor the quality of the softened water and initiate the regeneration cycle when the quality of softened water begins to deteriorate. Demand-initiated regeneration units provide the convenience of fully automatic softeners while also conserving salt by only initiating a regeneration sequence when it is required to maintain water quality. Modern softeners continue to improve. Most recently, computer control of the regeneration sequence has been introduced. In such models, the computer calculates the most efficient quantity of salt to be used for regeneration based on the volume of water treated the hardness level in the water, and historical data on regeneration efficiency. The computer then controls the regeneration sequence accordingly.

All the water softening systems described above are variations of the basic system described. In all cases the basic system consists of a pressure vessel containing ion exchange resin beads, along with a brine tank in which salt is stored and the brine is made. An entirely different approach can be used with portable exchange tanks (PET). PET systems do not have a separate tank for storage of salt and brine generation. Instead, a PET system consists of a tank or cartridge containing ion exchange resin. This tank is equipped with special fittings designed for easy connection and disconnection of the tank. The PET softeners do not include the valving or controls required for regeneration. Instead, when regeneration is required, the tank is disconnected and transported to a central station or plant for regeneration. When regeneration is complete the unit is returned, reconnected, and returned to service.

The early evolution of water softeners corpus christi was toward a higher degree of automation and sophistication. More recently, the need to conserve water has lead to the development of units that use less water during the regeneration cycle. Such units incorporate features such as: Smaller-sized ion exchange beads; Packed beds of ion exchange resin, with no freeboard in the tank; Smaller tank diameters; the use of less ion exchange resin and Countercurrent regeneration. It is important to buy the best water softeners from a reputed store.
