Abstract
A plurality of reverse osmosis units each having a cavity and a membrane are placed within a deep channel. The channel contains an unpurified liquid, and the membranes communicate directly with the unpurified liquid in the channel. The level of unpurified liquid is such that the differential pressure across the membranes is sufficient to cause purified liquid to accumulate in the cavities, from which it is emptied and pumped to the surface. The high pressure sides of the membranes are flushed by unpurified liquid being pumped through the channel. In this manner, a relatively large percentage of the channel diameter can be utilized, and the mechanisms can be implied over prior systems in which unpurified and purified liquids are piped from one reverse osmosis unit to another.
