Patent number: 9650270Abstract: 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.Type: GrantFiled: March 9, 2016Date of Patent: May 16, 2017Assignee: SILVER BULLET WATER TREATMENT COMPANY, LLCInventors: David Kolstad, David Sunshine

Patent number: 9597615Abstract: A fluid handling and separation system has an inlet conduit for receiving a helical fluid flow, a housing connected to the inlet conduit, a collection conduit disposed within the housing in axially alignment with the inlet conduit, and a diversion conduit in fluid communication with the interior of the housing. The housing encloses the collection conduit to form an annular space between the interior surface of the housing and an exterior surface of the collection conduit. Upon receiving a helical flow via the inlet conduit, a radially outward portion of the helical flow is separated from a radially inner portion of the helical flow. The radially outward portion of the helical flow is diverted through the diversion conduit while the radially inward portion of the helical flow is received by the collection conduit. Such a system allows for separating the helical fluid flow by density of materials or fluids within the helical fluid flow.Type: GrantFiled: November 8, 2013Date of Patent: March 21, 2017Assignee: SpiroFlo Holdings, Inc.Inventor: Alan Miller
