by:Directed Technologies Drilling Incorporated (DTD) based inBremerton, WASHINGTON (USA)
Free product recovery can often be accomplished in areas affected by floating product by using horizontal wells to draw down the water table and extract free product. Actual design of a recovery system will depend on site-specific circumstances, but all of the general advantages of horizontal wells can be applied to free product recovery. In some cases a dual-phase extraction system can be ...
by:Environmental Reclamation Services (ERS) Ltd based inGlasgow, UNITED KINGDOM
They pose risks to health and the environment due to their partially-soluble and volatile nature and the high toxicity of primary compounds and their breakdown products. Chlorinated solvents form liquids that are denser than water. Such dense non-aqueous phase liquids (DNAPLs) tend to migrate down through soil and groundwater following complex paths and can often be present at ...

by:Redox Tech, LLC based inCary, NORTH CAROLINA (USA)
Redox Tech utilizes steam for two main purposes. One purpose is to reduce the viscosity of free product, either LNAPL or DNAPL, so that it can be recovered more efficiently. The low-quality steam also helps to displace the less viscous free product. The second purpose involves heating the subsurface environment to thermally catalyze sodium persulfate. A total organic carbon ...
