The Effect of Wastewater Treatment on Methanogenesis in a Marine Outfall

Description
Summary:Methanogenesis in the Avalon outfall sediments of Santa Catalina Island, California, was monitored in its natural environment before and after the initiation of wastewater treatment. After treatment began, the outfall sediments were less reducing and contained less organic matter, which led to a thirtyfold reduction in the rate of methane production. High concentrations of sulfide and the presence of active sulfate-reduction did not inhibit methanogenesis, contrary to the observations in lacustrine sediments. Methanogenesis was observed to recycle annually 0.13% of the organic carbon.
