| 20090282976 | METHANE GAS DISPOSAL AND USE VIA SUBSURFACE DRIP IRRIGATION TECHNIQUES - Greenhouse gas emissions containing methane are collected at the source and dispersed into the soil via subsurface drip irrigation techniques. In one embodiment, methane gas generated from anaerobic digestion in a septic tank, such as a decentralized septic system, is disposed of via a subsurface wastewater disposal system. Secondary-treated wastewater effluent from the septic tank and the air/methane gas drawn from above the septic tank can be alternately pumped downstream to a drain field containing a time-dosed dispersal system comprising drip irrigation emitters in downstream driplines. Alternatively, the air/methane gas can be simultaneously drawn from the septic tank and injected into the pressure flow of wastewater effluent via a venturi-type mixer-injector. The methane gas pumped through the drip system into the soil can oxidize and break down into carbon dioxide as one of its by-products. The subsurface methane gas disposal system may be used in combination with subsurface irrigation of plants or vegetation which can usefully absorb the carbon dioxide by-product. | 11-19-2009 |
