I did not think that this would work, my best friend showed me this website, and it does! The advantages of anaerobic digestion over aerobic wastewater treatment are lower electrical power usage, the production of energy in the form of methane gas, and lower microbial cell (sludge) production. A Focus on Anaerobic Treatment There are 2 major types of systems used for wastewater treatment: aerobic and anaerobic systems. Over the past decades, anaerobic biotechnology is commonly used for treating high-strength wastewaters from different industries. so many fake sites. The fermentation process in which organic material is degraded and biogas (composed of mainly methane and carbon dioxide) is produced, is referred to as anaerobic digestion. Methane production rate increased from 0.29 to 1.46 L CH4/g COD, when the loading rate was increased from 2.0 to 8.26 g COD/L/day. The anaerobic digestion process is a fermentation pro-cess, which takes place in a closed airtight digester where organic raw materials such as manure, food waste, sewage ... at waste water treatment plants. Methane, CH4, produced in anaerobic digestion is a valuable renewable energy source. Anaerobic treatment of a volatile fatty acid (VFA) mixture was investigated under psychrophilic (3 to 8°C) conditions in two laboratory-scale expanded granular sludge bed reactor stages in series. The results showed the applicability of MMGM to predict usable methane component of biogas produced during anaerobic digestion of brewery wastewater. So far, anaerobic digestion (AD)-based wastewater treatment processes have been seldom applied in China due to the often unfavorable wastewater properties and suboptimal operation performances. Why Anaerobic Digestion? Treatment of high protein & nitrogen containing wastewater The anaerobic degradation of proteins produces amines which are no longer be degraded anaerobically.
