Apparatus And Method For Removing Volatile Contaminants From The Ground
US Patent:
4982788, Jan 8, 1991
Filed:
Mar 10, 1989
Appl. No.:
7/321936
Inventors:
Lawrence A. Donnelly - Centerport NY
International Classification:
E21B 4324, E21B 4340, E21B 2300, E02D 311
US Classification:
166266
Abstract:
Hazardous volatile contaminants are removed from the ground by circulating air between two substantially parallel wells and by removing the vapors of the organic compound from the circulated air using at least one of a condenser and a demister. To enhance efficiency the air is recirculated in a closed loop. The heat output of the condensation process is used to heat the recirculated air. Pipes having openings along only a limited portion of their lengths are placed in the wells and the depth of the openings adjusted to treat one level at a time, thereby preventing shunting of air through more porous soil layers. Flow rates can be equalized by using circumferentially placed induction wells surrounding an extraction well (or the reverse) and by controlling air flow through individual sections of a given level.

Assignee:
Grumman Aerospace Corporation - Bethpage NY
International Classification:
C02C 506, C02B 138
US Classification:
210 44
Abstract:
A method for waste treatment including the steps of and the associated apparatus for removing large solid waste from the influent raw sewage, transmitting the large solid waste to an incinerator, subjecting the resultant liquor to centrifuging to separate additional suspended solids therefrom, passing the additional suspended solids to the incinerator, subjecting the remaining clarified liquid to ozonation to entrap and bubble out remaining solids, to oxidize residual organic contaminants in the liquid, and to disinfect the liquid, and transmitting the solids to the incinerator. The effluent liquid resulting from ozonation can be recycled or discharged into a suitable receptacle, or it may be treated further by activated charcoal and/or reverse osmosis or similar tertiary treatment technique before recycling or discharging.
