Abstract

In India, to achieve the stringent norms of total nitrogen less than 10 mg/l in sewage treatment plant is a big challenge for the public - private facilities and organizations. After successful implementation of this norm the pollutant burden from rivers and natural water bodies certainly reduces. The use of conventional biological nitrogen removal (BNR) processes for new treatment facility development or retrofitting is also an energy and cost intensive practice. The process technologies offered by current market such as MLE, MBBR, IFAS and SBR are still in with downside of higher footprint, multi tank reactors, heavy instrumentation for IR and RAS which ultimately incur higher capital and operating cost. The current market need and lack of sustainable nitrogen removal applications, trigger to review the of all available efficient biological nitrogen removal processes. This review will gives an overall scenario of past and current biological nitrogen removal process technologies with showing possible scope and way forward towards more energy neutral nitrogen removal technologies.
