Electrolysis based water treatment
First Claim
1. A method of treating water, the method comprising the steps of:
- providing one or more pairs of electrodes, and immersing the one or more pairs of electrodes in water to be treated;
delivering an instantaneous electric current determined by the instantaneous conductivity of the water via the one or more pairs of electrodes to the water, whereby sacrificial ones of the electrodes provide dissolved ions to assist in treating the water to remove contaminants; and
monitoring a cumulative amount of charge passed through the water, the cumulative amount of charge being indicative of a degree to which the water has been treated.

Abstract
Water treatment involves delivering an instantaneous electric current to one or more pairs of activated electrodes immersed in the water, each of the pairs of electrodes comprising a sacrificial electrode operating predominantly as an anode and an inert electrode operating predominantly as a cathode. The sacrifical electrode, when as an anode, is able to provide dissolved ions to the water as current passes between the pairs of electrodes, to assist in treating the water. The polarity of the electrodes is periodically reversed to reduce electrode clogging. The amount of charge passed by the instantaneous electric current is indicative of the degree to which the water has been treated, and is used to control the treatment process.

9. A water treatment unit apparatus comprising:
-
a tank for receiving water to be treated;
one or more pairs of electrodes provided within the tank for immersion in the water;
a power supply to deliver an instantaneous electric current determined by the instantaneous conductivity of the water through the pairs of electrodes to the water, whereby sacrificial ones of the electrodes provide dissolved ions to assist in treating the water to remove contaminants; and
