Document Description
Under the oversight of the Regional Board, ConocoPhillips proposes to use C-Sparge (TM) to remediate the dissolved-phase petroleum hydrocarbon plume beneath the site. The C-Sparge (TM) 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 micrometers [um] in diameter) of encapsulated ozone are introduced below the water table, where the oxidatoin reactions take place.
