Thermally enhanced soil air circulation (TESAC)

2008/04/02, Wednesday
Soil air circular flow is employed to remediate soils polluted with volatile contaminants (e.g. CHC, BTEX, jet fuels), some semi-volatile contaminants and/or biodegradable substances. Due to the application of low negative pressure, TESAC systems can be implemented in soil, where the horizontally induced flow bypasses contaminants trapped in low-permeability layers.

传统的气提技术已被证明是一个去除挥发性和半挥发性有机物的实用并价廉的有效方法。通常，气提法使用刚到达地下水位下一点的小型钻孔和直径最大为50毫米的漏筛。根据设备的大小和土壤性质的不同，鼓风机运行产生的压力通常在100-300 毫巴的范围，就是这样的负压将毛细管水引出土壤毛细管并进入土壤通风系统中。常规的气提系统也会在井的漏筛段附近产生紊流，并明显地降低其通风力。高负压下的紊流气体也会导致系统鼓风机温度过热

Soil Air Circulation - Bioventing

2006/09/12, Tuesday
Directed Soil Air Circulation systems (SAC) are employed for the remediation by Bioventing of soil contaminated with volatile hydrocarbons by enhancing the IEG Vacuum Vapor Extraction (IEG VVE) technique. In addition, they can be used to inject gas into the soil for the stimulation of biological or chemical degradation.
