Water Treatment Device And Methods Of Use
US Patent:
8361384, Jan 29, 2013
Filed:
Aug 3, 2009
Appl. No.:
12/534761
Inventors:
David Kolstad - Denver CO, US
Assignee:
Aardvark IP Holding, LLC - Denver CO
International Classification:
A61L 2/00
G01N 21/00
A61N 5/00
G01N 21/00
A61N 5/00
US Classification:
422 24, 422905, 25045511, 2504921, 21074801, 21074803, 2107481, 21074811
Abstract:
A water treatment device and methods of treating cooling tower water are described. The water treatment device utilizes ultraviolet radiation, a magnetic field, and ozone fortified air to treat cooling tower water, resulting in reduced microbial contamination and reduced alkalinity in cooling tower water. Cooling tower water may consequently be run at higher cycles of concentration while reducing or eliminating deposition of minerals on cooling tower components.

US Classification:
210695, 210251, 210223, 210758
Abstract:
A water treatment device and methods of treating water such as cooling tower water, swimming pool water, and hot tub or spa water, are described. The water treatment device utilizes ultraviolet radiation, a magnetic field, and ozone fortified air to treat the water, typically resulting in reduced microbial contamination and reduced alkalinity in cooling tower water. Cooling tower water may consequently be run at higher cycles of concentration while reducing or eliminating deposition of minerals on cooling tower components. Swimming pool water and hot tub water treated with the water treatment device typically requires less chlorine, and chlorine levels are typically more stable than without the device.

International Classification:
C02F 1/32
US Classification:
210695, 2101981, 21016711, 210200, 2107481, 21074812
Abstract:
A water treatment device and methods of treating water such as cooling tower water, agricultural water, water used in the production of oil and/or gas, swimming pool water, and hot tub or spa water, are described. The water treatment device utilizes ultraviolet radiation, a magnetic field, and ozone fortified air to treat the water, typically resulting in reduced microbial contamination and reduced alkalinity in cooling tower water. Cooling tower water may consequently be run at higher cycles of concentration while reducing or eliminating deposition of minerals on cooling tower components.

Water Treatment Systems And Methods
US Patent:
2016008, Mar 24, 2016
Filed:
Feb 9, 2015
Appl. No.:
14/617632
Inventors:
- Denver CO, US
David Kolstad - Denver CO, US
David Kolstad - Denver CO, US
International Classification:
C02F 1/72
C02F 1/78
C02F 1/78
Abstract:
A water treatment device for treating water in water systems such as cooling towers, evaporative coolers, swimming pools, fountains, sewage wastewater systems, water troughs for agricultural animals, agricultural runoff, and fisheries is described. The water treatment device utilizes a magnetic field, a catalyst, and ultraviolet (UV) radiation to produce a treated gas with increased oxygen radicals to treat a body of water. A mount disposed about a UV lamp may comprise the catalyst material or materials to increase the production of oxygen radicals. The resulting treated gas may be placed in contact with a body of water, for example, to reduce particulate build up, biological matter, and other pollutants.
