Abstract
A water purification system and method using an ionizer and an ozonation treatment for ionization, oxidation and/or decomposition of undegradeable contaminants is disclosed. A high electron-inducing voltage is first applied to the water in the ionizer so that undergradeable materials are ionized and/pr decomposed, then the water is mixed with ozone so the water is purified to be potable.
Claims16
A water purification system, comprising:
- at least one ionizer including:
- a cylindrical chamber having an inlet and outlet for water flow;
- at least one rod anode which is surrounded with a coaxial cylindrical dielectric sheath;
- at least one cylindrical mesh grid which is coaxial with and surrounds the cathode;
- and
- an ozone generator for producing ozone;
- and
- an ozone mixer for mixing the water with ozone provided by the ozone generator.

An ionizer used in a water purification system, comprising:
- a cylindrical chamber having an inlet and an outlet for water flow;
- said chamber made to permit the water to flow along a flow path from the inlet to the outlet;
- at least one rod anode which is surrounded with a coaxial cylindrical dielectric sheath;
- at least one rod cathode which is surrounded with a coaxial cylindrical dielectric sheath;
- and
- at least one cylindrical mesh grid which is coaxial with and surrounds the cathode,
- wherein both ends of the cylindrical chamber are hermetically capped by a mounting fixture made to provide a waterproof fit.
4 more elements
A method for purifying water, comprising the steps of:
- (a) providing at least one ionizer adapted to create an electric field;
- (b) energizing the ionizer with a high voltage, such that an electric field is created;
- (c) passing the water through the ionizer so decomposition and oxidation of the indecomposable materials is performed;
- (d) filtering sludge which is formed in the above step;
- (e) introducing ozone into the water to mix ozone with the water;
- and
- (f) filtering sludge which is formed in the above steps.
