ABSTRACT
Treating municipal sewage anaerobically results in a clean disposable effluent, biogas and low quantities of biosolids. Anaerobic digestion of sewage has many advantages, which include environmental and economic benefits from the biogas production. Biogas generated from sewage plants has potential to be applied as a substitute energy resource for heating purposes as well as electricity generation to meet the sewage plants' electricity demands. The replacement of fossil fuels by biogas will result in the decreased release of carbon dioxide and methane, which are the major greenhouse gases in the environment causing global warming. The treatment of sewage wastewater with Hycura allows for the recovery of bionutrients, in particular total phosphates and total Kjeldahl nitrogen, and sewage bionutrient removal can be measured by its biodegradability and denitrification, which focuses on organic matter removed per sample of sewage.
