Abstract

The present disclosure relates to a Reverse Osmosis based potable water system (200) for water filtration that can provide improved yield of potable water thereby reducing the wastage of water. In an embodiment, the improvement in yield is achieved by providing two RO units (208 and 220) that can be configured in series in such as a way that retentate from the first RO unit (208) is fed as input to the second RO unit (220), through a control valve to get an additional yield of potable water. The potable water purification system 200 includes means, such as piping unit 226 or pumps (210, 218) for maintaining required flow and appropriate pressure level of feed water at different stages, so as to get high yield of pure water and increase the life of the semipermeable membranes.
