Abstract
A method and apparatus for purifying water to two different laboratory quality levels of purity, both of which are made available for dispensing. Ordinary tap water is prefiltered and treated by reverse osmosis to produce virtually salt free product water which is made available to a cabinet mounted faucet. The product water is delivered to a system of polishing cartridges which produce polished water and supply it to a special hand held dispensing gun. A recirculation pump operates to recirculate the water in the polishing system to prevent it from standing and eliminate the need for water storage. The product water is also recycled through the reverse osmosis cartridge. Some of the reject water from the RO cartridge is directed to a drain, but most of the reject water is recycled to conserve water. A microprocessor based control system monitors and displays the water quality and other conditions and generates an alarm if an abnormal condition arises.
