Abstract
Abstract An apparatus and method of reducing agglomeration of fluids consisting of the vigorous agitation of the liquid by a double opposed vortex nozzle and the passing of the liquid through a magnetic field. One of the opposed nozzles may have ozone gas forced through it for treating sewage. The apparatus and method may also be used to treat cooling tower water.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
67 words
A method for treating water in cooling towers comprising the steps of: pumping the water through a first vortex nozzle; simultaneously pumping the water through a second vortex nozzle; agitating the water by spraying the water exiting the first vortex nozzle against the water exiting the second vortex nozzle; and simultaneously magnetically affecting the water by a magnetic affecting means mounted in close proximity to the nozzles.
Claim 2
Independent Claim

Claim 3
Independent Claim
124 words
An apparatus for treating water in cooling towers comprising: means for pumping water from a cooling tower; said pumping means connected to a means for agitating said water; a magnetic affecting means mounted in close proximity to said agitating means for magnetically affecting the water as it is pumped through said agitating means; said agitating means further comprised of an inlet, a vortex apparatus connected with said inlet, and an outlet connected to said vortex apparatus; said inlet and said outlet connected to said pumping means; said vortex apparatus comprised of vortex nozzles mounted within means defining a chamber in opposed relationship to each other; and said nozzles oriented so as to direct the water from one nozzle against the water from another nozzle.
