ABSTRACT:
A water treatment system having dosing control for providing treated water having very low organic and ionic contamination, that can be accurately dispensed. The water treatment system having dosing control includes a water inlet hydraulically connected to a pump having a variable speed motor. At least one water treatment device is hydraulically connected downstream of the pump, at least one outlet valve is hydraulically connected downstream of the water treatment unit, and a recirculation line is hydraulically connected from the outlet valve to the pump. The output of the pump is controlled by a regulating device connected to the variable speed motor. The system provides for lower electrical current usage and reduced acoustical disturbances.
