Abstract

The biogas produced at the Bucklin Point Wastewater Treatment Facility contained a high concentration of siloxane compounds. A manufacturer of personal care products was found to be the major source of the siloxanes. Much of the siloxane that the manufacturer discharged to the sewage collection system entered the anaerobic digestion system, where more than half of these compounds were released into the biogas. All the siloxanes in the biogas likely oxidized to silica when the biogas was combusted, and a portion of the silica deposited in the boiler and impeded heat transfer efficiency. Condensation followed by carbon adsorption was found to have the potential to economically remove siloxanes present above a certain threshold concentration.
