 Examples of low temperature ERH include heat-enhanced bioremediation, heating the subsurface to temperatures above the solubility of dissolved gasses to induce VOC stripping (most notably carbon dioxide ebullition), heat enhanced in situ chemical oxidation (especially for persulfate activation), and heat-enhanced reduction (such as with iron-catalyzed reactions).ERH low-temperature heating can also be used to hydrolyze chlorinated alkanes in-situ at sub-boiling temperatures where hydrochloric acid released during hydrolysis further reacts with subsurface carbonates and bicarbonates to produce carbon dioxide for subsurface stripping of VOCs.Using low temperature heating coupled with bioremediation, chemical oxidation, or dechlorination will result in increased reaction rates.
