Document Description
Under the oversight of the Los Angeles Regional Water Quality Control Board, ConocoPhillips Company proposes to operate a C-Sparge™ system to remediate the dissolved-phase petroleum hydrocarbon plume beneath the site. The C-Sparge™ technology combines low-flow (3 to 5 cubic feet per minute [cfm]) air sparging with ozonation to oxidize petroleum hydrocarbons into benign byproducts, carbon dioxide and water. Ozone is generated onsite using a control panel with built-in compressor and ozone generator. Using perforated sparge points, microbubbles (10 to 50 µm) of encapsulated ozone are introduced below the water table, where the oxidation reactions take place.
