Abstract
A system for softening of water in a manner to minimize heat requirements in the water softener unit of the system. Flashed water vapor from a flash box coupled to the downstream end of the softener unit is used to preheat incoming hard feed water by directly contacting the feed water in respective preheating chambers upstream of the softener unit. The system is suitable for use in a distillation plant to produce potable water.
