<p>A method of purifying fluids in which a filter (42) is disposed at sufficient depth in a channel (20), a fluid is electrolyzed to produce a gas, and expansion of the gas is used to raise the filtrate upwards. The methods are contemplated to be particularly useful with salty or brackish feed fluids (74), and in which the channel provides a head pressure equivalent to a depth of at least 100 meters, or more preferably several hundred meters. The electrolysis preferably employs a catalyst, and produces hydrogen and oxygen.</p> |
