ABSTRACT:
Water treatment apparatus having a raw water inlet and a treated water outlet and at least a first and second water treatment tank plus conduit means for passing water from the inlet to the outlet through the first and second tanks in parallel flow relation. The tanks are automatically regenerated in sequential, alternating intermittent manner in response to predetermined criteria. The tank being regenerated is connected to prevent flow from said tank through the outlet, while the tank not being regenerated is connected to provide flow through the outlet. Accordingly, continuous water treatment, with alternating, intermittent regeneration of the tanks, may be provided.
