Performance of Acid-Gas Anaerobic Digestion for Minimization of Siloxane and Hydrogen Sulfide Produced in Biogas for Energy Recovery
… of wastewater treatment facilities. During anaerobic sludge digestion, these compounds volatilize and enter the methane gas recovery stream. As the methane is combusted for energy cogeneration, these compounds become oxidized to microcrystalline silicon dioxide and cause damage and potential …
