Abstract
Water purifier using membranes, ion exchange resins and electricity to remove ionic, organic and suspended impurities from water to produce high quality, pure water. Supply water is pre-treated by directing it first into a sediment pre-filter module, a softener module and a sediment removal and dechlorination module. The pre-treated water is supplied to a reverse osmosis module which separates the water into two streams (a purified water stream and a concentrate stream) by collecting fluids from both sides of pressurized membranes. The purified water is passed to an electrodeionization module which further purifies the water and directs the water to an ultraviolet sterilization module. The concentrate stream is divided into a recycle stream which is passed to the inlet of the reverse osmosis module and a waste concentrate stream which flows to an outlet of the machine. A control method for the water purifier is also disclosed.
