The clean effluent prevents biomat formation and leachfield clogging. Denitrification is primarily performed by bacteria that are heterotrophic, meaning they require a carbon source for growth and energy. The operation of wastewater treatment plants results in direct emissions, from the biological processes, of greenhouse gases (GHG) such as carbon dioxide (CO 2), methane (CH 4), and nitrous oxide (N 2 O), as well as indirect emissions resulting from energy generation. Foaming in activated sludge process is a common operational problem in many wastewater treatment plants.

The Moving Bed Biofilm Reactor is a fixed-film biological process used for BOD removal, nitrification and denitrification. The obvious economic advantage, both in terms of capital investment and Nitrification is a microbial process by which reduced nitrogen compounds (primarily ammonia) are sequentially oxidized to nitrite and nitrate. Denitrification is the dominant, sustainable removal process in wetlands that receive high nitrate loadings from agricultural runoff or wastewater treatment plant discharge. This septic technology is very compatible with shallow drip, direct discharge, pressure distribution, spray irrigation, and conventional leachfield. An MABR module conducts them in one tank in a process called simultaneous nitrification and denitrification (SND). However, sometimes denitrification can be disadvantageous by removing the NO 3 – present in the soil, thus reducing the extent of leaching. Creating the ideal environment for nitrification. Wastewater treatment is a vital component in any community without which water-borne pathogens can spread resulting in diseases and degradation of receiving water bodies.
