Pressure In Line Degassing Process In Water Treatment
US Patent:
2009017, Jul 16, 2009
Filed:
Jan 14, 2008
Appl. No.:
12/008665
Inventors:
George J. Crits - Ardmore PA, US
William J. Runyan - West Chester PA, US
William J. Runyan - West Chester PA, US
International Classification:
C02F 1/20, B01D 46/46
US Classification:
95 24, 95259, 210664, 210750
Abstract:
When water sprays into an empty tank or into the freeboard of filters, considerable flashing occurs to release about 50 to 80% of carbon dioxide, hydrogen sulfide, and other gases. The injection of air with the water enhances this degasification and produces a partial drained tank, in which it is required for the spraying or flashing to occur. When the water level reaches a low point, a switch signals for the vent to be opened and the air is stopped. But the inlet water continues to fill the tank and to displace the gasses through the vent. When the water reaches the vent, a high level switch closes the vent. Air injection starts again to repeat the cycle. Alternately, the injection of air with the influent water into a partially drained tank with a level controller and venting also effects this degasification.
