Introduction
Anaerobic wastewater treatment, a method that is widely used all over the world, is the biological treatment of wastewater without the use of air or elemental oxygen. During anaerobic treatment, the organic pollutants are converted to a gas containing methane (C[H.sub.4]), carbon dioxide (C[O.sub.2]), ammonia (N[H.sub.3]), and hydrogen sulfide ([H.sub.2]S) by anaerobic microorganisms. Anaerobic wastewater treatment has several advantages as compared with aerobic wastewater treatment. It uses less energy since aeration is not needed, the organic matter in the influent is converted into a valuable gas, and less surplus sludge is formed because the growth rate of anaerobic microorganisms is lower. The increased utilization of anaerobic wastewater treatment systems has been associated wit...See the full content of this document
