Reverse osmosis water purification system for use in limited water supply installations
TLDR
A reverse osmosis water purification system for purification of water received from a supply tank having a limited and exhaustible supply of water is presented in this article, where water is extracted from the supply tank by a pump which directs the extracted water under pressure to a reverse Osmosis unit.Abstract:
A reverse osmosis water purification system for purification of water received from a supply tank having a limited and exhaustible supply of water Water is extracted from the supply tank by a pump which directs the extracted water under pressure to a reverse osmosis unit which in turn directs the purified water to a hydro-pneumatic storage tank with the waste water produced by the reverse osmosis unit being returned to the supply tank for water conservation purposes The system further includes a pressure sensing switch associated with the hydro-pneumatic storage tank and the pump to maintain the differential pressure across the reverse osmosis unit in a predetermined pressure rangeread more
