De-nitrification process in sewage plants
Webammonia. Nitrification is a biological process that converts ammonia to nitrite and nitrite to nitrate. If standards require that the resulting nitrate be removed, one treatment alternative is the process of denitrification, in which nitrate is reduced to nitrogen gas. One treatment … WebOne reason is the potential of the denitrifying process to alleviate environmental impacts of NO 3 − in ground- and surface waters via the enzymatic reduction of NO 3 − in stream sediments, constructed wetlands, riparian buffer strips and biological sewage treatment plants. Increased interest in denitrification in the biosphere has also ...

WebJan 31, 2024 · Biological treatment processes perform satisfactory in wastewater treatment, but the relatively high cost and complicated maintenance limit its application in rural areas. In this study, a highly packed biofilm reactor (HPBR), with a 90% packing ratio of carriers in the bioreactor, was designed for rural wastewater treatment. The results showed that … WebExtended aeration plants are usually started up using "seed sludge" from another sewage plant. It may take as many as two to four weeks form the time it is seeded for the plant …
WebA large problem in some plants is a low pH (to as low as pH = 6) caused by extensive nitrification and low wastewater alkalinity. This often causes pin floc and high effluent turbidity. Some plants reduce aeration to reduce nitrification or add soda ash, lime or magnesium hydroxide as a source of alkalinity if this becomes a problem.
