Novel reverse osmosis water treatment system that rationalizes the wasted water as a result of water treatment

摘要

The present invention provides a household water treatment system by harnessing the Reverse Osmosis (RO) characteristic, wherein such system is characterized by rationalizing the amount of wasted water left after the water treatment process completely without negatively affecting the system components and by increasing the efficiency and quality levels as well as the durability of the system’s components. The system of the present invention essentially comprises a water feeding and draining unit, a household water treatment unit with a special holder for an RO membrane to keep vibrating, a fresh water storage unit, a drain water storage unit, and a dual inlet water faucet. The system of the present invention stores the salt water resulted from the household water treatment process in said drain water storage unit in order to be used in domestic processes that do not need fresh water such as washing fruits and vegetables, and washing kitchen utensils. The traditional drain restrictor is modified in the system of the present invention to a self-calibrating drain restrictor to maintain a constant operating pressure on the RO membrane, and to prevent blockages in such restrictor as a result of calcification. In the system of the present invention, continuous water feeding for said household water treatment unit is maintained through using same diameters of feeding passages and through designing a mixing chamber in a way that permits good water feeding for both the main water faucet when operated, and the household water treatment unit.
