Effective microbial consortia to treat wastewater on site

Abstract

It is an established fact that India faces major problem of sewage treatment and disposal due to paucity of adequate sewage treatment infrastructure. Conventional treatment techniques come with a lot of economical issues due to cost factor. An alternative economical substitution is the on site treatment of wastewater flowing into open drains. Onsite bioremediation offers treatment of sewage in the running battery of flow without displacing; and by employing microbial consortia in the aerobic and facultative environment to degrade sewage resulting into CO2 and H2O and reduce odour. In the present paper bioremediation based onsite sewage treatment technologies, effective microbial consortia and its application to treat wastewater are discussed and a summary of studies on the use of effective microbial consortia is also presented.
