USE OF ENCAPSULATED SUBSTRATES THAT CONTROLTHE RELEASE RATES OF ORGANIC HYDROGEN DONORS

摘要

Anaerobic reductive dechlorination processes remove chlorinated solvents from contaminated subsurface soil and ground water. The presence of organic hydrogen donors enables anaerobic microorganisms present in the subsurface soil and groundwater to accelerate the reductive dechlorination process. The present invention provides an alternative method to control the release rate of organic hydrogen donors during dechlorination. The invention utilizes encapsulated substrates to control the release rate of organic hydrogen donors, therefore accelerating the biotic process of anaerobic reductive dechlorination.
