Abstract: An apparatus and method for ozone-aerating fluid is connected to a conventional water treatment system that includes a high pressure fluid pump and a high pressure filter connected to a main reservoir. Included is an auxiliary reservoir and low pressure filter. A first valve controls the fluid flow in a conduit connected to the output of the high pressure filter. A second valve controls the flow of fluid output from the filter to a lift tube. Ozonated air bubbles are injected into fluid in the lift tube. The fluid flows up the lift tube and into the auxiliary reservoir due to expansion of air bubbles. The fluid flows out of the auxiliary reservoir and filter under the force of gravity into the conduit on the downstream side of the first valve and into the main reservoir. A UV germicidal lamp may be positioned in the path of fluid flow.

Abstract: Described herein is a method for differentially lysing a liquid sample or target material using an Augmented Oxidizing Agent (AOA), which includes a quantity of Electronically Modified Oxygen Derivatives (EMODs). The method reduces or eliminates total dissolved solids (TDS), total suspended solids (TSS), microbial concentration, biofilms and other content in the liquid target material known or suspected to contain animal fluids, blood and blood cells and suspected or known to contain eukaryotic cells, microbial cells, bacteria, viruses, spores, fungi, prions, organic matter, minerals, proteins or associated structures. The TDS and TSS can be lowered or eliminated as desired. This action is directly proportional to the quantity of EMODs in the AOS applied to the liquid target material.
