Patent ID: 7052600

Claim:
A cooling water system having a condensing water loop, comprising: a condenser system; a cooling tower having water sides surfaces and a basin; a water treatment apparatus comprising: a pump having: an inlet port and an outlet port, said inlet port being connected to an incoming water line for supply water to be treated, drawn from the condensing water loop of the cooling water system; a first electrode ionization chamber comprising: an inlet port and an outlet port, said pump outlet port communicating with said first electrode ionization chamber inlet port; and two ion-producing electrodes spaced apart, wherein at least one of said ion-producing electrodes comprises a titanium electrode coated with ruthenium for the purpose of creating nascent oxygen, molecular oxygen, ozone, hydroxyl and perhydroxyl radicals, and hydrogen peroxide in said water; and a second electrode chamber comprising: two ion-producing electrodes spaced apart; and an inlet port and an outlet port; and a quantity of water to be treated, the quantity of water to be treated being located in the condensing water loop between the cooling tower and the water treatment apparatus, wherein the electrode chambers communicate with the condensing water loop such that water in the loop is circulated through the electrode chambers.
