Method And System For Removal Of Volatile Contaminants From Water Supplies

US Patent:
2013001, Jan 17, 2013
Filed:
Jun 11, 2012
Appl. No.:
13/493117
Inventors:
Ethan Brooke - Biddeford ME, US
Michael Robin Collins - Lee NH, US
International Classification:
C02F 1/58, C02F 1/20
US Classification:
210718
Abstract:
A method of and system for treating water to reduce the level of trihalomethanes or other volatile contaminants such as radon includes the water to be treated (WTBT) being sprayed through a nozzle to aerate the WTBT to increase the air/water interface therein reducing the level of trihalomethanes in the water. In one embodiment, the pressure of the WTBT in the nozzle is adjusted and the nozzle is selected to have a nozzle orifice such that the droplet size of the water to be treated from the nozzle is less than 2000 microns SMD. In addition, the nozzle is spaced from a holding tank for receiving and collecting the sprayed water such that the surface of the treated water is specified at a particular distance based on desired treatment goals.

System And Method For The Reduction Of Volatile Organic Compound Concentration In Water Using Pressurized Diffused Aeration

US Patent:
2013001, Jan 17, 2013
Filed:
Feb 16, 2012
Appl. No.:
13/398622
Inventors:
Ethan Brooke - Biddeford ME, US
Michael Robin Collins - Lee NH, US
John Michael Zwerneman - Dallas TX, US
International Classification:
C02F 1/20, B01F 3/04, C02F 101/30
US Classification:
210640, 210218, 2611191, 210143, 210750
Abstract:
The system and method reduces volatile organic compound concentration in a water distribution system using pressurized diffused aeration. The system and method is used in-line in a water distribution system. The system and method can be used at the ends of the distribution system where volatile organic compounds, including trihalomethanes, are more likely to persist. The system and method of pressurized, diffused aeration reduces volatile organic compounds from groundwater remediation systems as well.
