Abstract
A method of purifying fluids in which a filter is disposed at sufficient depth in a channel, a fluid is electrolyzed to produce a gas, and expansion of the gas is used to raised the filtrate upwards. The methods are contemplated to be particularly useful with salty or brackish feed fluids, 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.
Claims10
A method of purifying a fluid comprising:
- providing a deep channel;
- situating a filter at a first depth in the channel, the filter producing a filtrate from a feed fluid;
- providing a filtrate accumulation chamber with a plurality of electrodes at a second depth, wherein the filtrate accumulation chamber receives the filtrate from the filter, and wherein the filtrate accumulation chamber is fluidly coupled to a pump;
- providing a sufficient voltage across the plurality of electrodes to at least partially electrolyze a fluid to produce a gas;
- and
- raising the filtrate upwards using the pump and the gas to generate a rising force.
