ABSTRACT:
A reverse osmosis water purification system which has a tank coupled to an osmotic membrane so that the water within the tank flushes the osmotic membrane. The tank has an opening that is in fluid communication with a source of feed water and an osmotic membrane. The tank may also have a lower level switch and an upper level switch that are coupled to a pump that pumps water through the membrane. When the tank water falls to the level of the lower switch, the pump is activated and purified water is pump into the tank. When the tank water reaches the level of the upper switch the pump is deactivated. The opening is located at an elevation above the membrane, so that when the water level within the tank reaches the height of the opening, the feed water pump turns off and the tank water provides a hydrostatic pressure that drives the water back through the membrane to flush the same. The upper switch is located above the opening so that a sufficient amount of water flows back through the membrane.
