Abstract
A water treatment system including a plurality of treatment tanks containing a water treatment material and defining a fluid flow path through the material extending between a first tank port and a second tank port. A first remotely controlled three way valve associated with the first tank port controls the fluid communication of a source manifold and a regeneration discharge manifold with the first tank port of each tank. A second, remotely controlled three way valve controls the fluid communication of a product receiving manifold and a regeneration chemistry supply manifold with the second port of each tank. A regeneration control monitors the loading of each tank and initiates regeneration in a given tank when that tank reaches a predetermined exhaustion level. A regeneration anticipator is operative to initiate early regeneration of a given tank if it determines that a second tank will reach exhaustion before the first tank completes its regneration, if the first tank is allowed to proceed to the predetermined exhaustion level. The treatment tanks form part of a subassembly mounted on a common platform which is skid mounted to facilitate movement and service.
