Abstract:
The invention provides a water purification and dispensing system, preferably for producing ultrapure water and offering the purified water at one or more dispensing sites in a desired volume. The water purification and dispensing system comprises a (closed) water recirculation loop including a water inlet for introducing water to be purified, pumping means for pumping water through said water recirculation loop in a flow direction, water purification means for purifying water downstream of said water inlet, a dispensing portion of the water recirculation loop including one or more outlet(s) for purified water branched from said water recirculation loop downstream of said water purification means, a first valve arranged between each outlet and said water recirculation loop, for controlled dispensing of the purified water from said recirculation loop through the respective outlet, a second valve arranged in said dispensing portion of the water recirculation loop downstream of said first valve(s) and upstream of said pumping means, a bypass passage branched from said water recirculation loop and bypassing said dispensing portion of the water recirculation loop including said first valve(s) and said second valve, and a third valve for controlling the flow rate through said bypass passage.
