Comprehensive water treatment system
First Claim
1. In a method for the cyclic regeneration of a water softening system comprising an exchange medium in an exchange medium tank which is in fluid communication with a brine storage tank, which comprises the steps of:
- (a) filling said brine storage tank with a second refill of softened water in a quantity sufficient to create enough brine for said exchange medium, said brine storage tank already containing a first refill of softened water from a later step of the method;
(b) first backwashing of said exchange medium with water flowing counter to the direction of water flowing therethrough during water softening;
(c) passing brine from said brine storage tank through said exchange medium;
(d) passing water through said exchange medium;
(e) second backwashing of said exchange medium with water flowing counter to the direction of water flowing therethrough during water softening; and
(f) refilling said brine tank with said first refill of softened water to create brine in a quantity insufficient to brine said exchange medium.

Abstract
In its broadest aspects, a method for the cyclic regeneration of a water softening system is disclosed. The water softening system comprises an exchange medium in a tank which is in fluid communication with a brine storage tank. This method comprises the steps of filling the brine storage tank with a second refill of softened water in a quantity sufficient to create sufficient brine for said exchange medium, said brine storage tank already containing a second refill of softened water from a later step of the method. The exchange medium is subjected to first backwashing with water flowing counter the direction of water flowing therethrough during water softening operations. Next, brine from the brine storage tank is passed through the exchange medium. Water then is passed through the brine exchange tank. The exchange medium thereafter is subjected to second backwashing with water flowing counter to the direction of water flowing therethrough during the water softening operation. Finally, the brine tank is refilled with a first refill of softened water to create brine in a quantity insufficient for completely brining the exchange medium.
