Abstract:
A water treatment apparatus, comprising: an ionization chamber containing two spaced apart ion-producing electrodes and having an inlet port and an outlet port, said inlet port being connected to an incoming water line for supplying water to be treated to said chamber, and said inlet port and said outlet port being so arranged in separate, fluid flow communication with said chamber that water to be treated from said incoming water line will pass through said inlet port and around said ion-producing electrodes before flowing out of said chamber through said outlet port; and at least one of said ion-producing electrodes of said ionization chamber comprises plasma fused iridium coated titanium, the apparatus further comprising an ion controller, wherein one electrode acts as an original anode and the second electrode acts as an original cathode, the electrodes being positioned in the same chamber so that untreated water may be passed over each of the electrodes in a water treatment process, the ion controller being constructed and arranged to periodically reverse the direction of the current to the electrodes and change the polarity of the electrodes during a water treatment process so that the original anode becomes a cathode and the original cathode becomes an anode, to minimize electrode wear.
