Abstract:
A method of removing contaminants from influent water which comprises the steps of:(a) directing oxygenated ozone-treated water into an air saturator; (b) directing air at a pressure of between about 80 psi to about 150 psi into said air saturator to saturate said oxygenated ozone-treated water thereby creating a high-pressure oxygenated ozone-treated water mixture; (c) directing said high-pressure oxygenated ozone-treated water mixture to a blender; (d) at a pressure substantially lower than the pressure of said high-pressure oxygenated ozone-treated water mixture, directing influent water containing at least some contaminants to said blender; (e) mixing said high-pressure oxygenated ozone-treated water mixture and said influent water thereby creating a plurality of micro-bubbles and entraining particles in a resulting white-water mixture; (f) directing said white-water mixture to a separator; (g) effecting said directing of steps (c), (d), and (f) by a suction pump attached between an outlet port of said blender and an inlet port of said separator; (h) causing said white-water mixture to rotate about an axis in said separator so that waste water, with entrained contaminants, is separated from said white-water mixture by coalescing along said axis, and decontaminated water separated from said white-water mixture away from said axis and from said waste water; (i) removing said waste water; and (j) removing said decontaminated water.
