ABSTRACT:
A process and system (100) for purifying water includes a pair of electrodes (52) with a gap (58) between the electrodes (52). The electrodes (52) are connected to a power supply (116) that places a voltage across the two electrodes (52). Raw water (51) is then passed through the electrodes (52) which captures a plurality of ionic species (224) resulting in purified water (64). A system (100) that takes advantage of this process has a container (102) that holds the pair of electrodes (52) or filter (102). A controller (120) connected to a current sensor (118) monitors the current across the electrodes (52) and adjusts a valve (108) based on the current. If the current is above a first threshold the water flow is decreased and if the current flow is below a second threshold the water flow is increased.
