Aerobic wastewater treatment technologies: A mini review

Abstract:

Treatment of sewage water from industries or domestic becomes very crucial in present days. For concentrated industrial wastewater aerobic treatment is a substitute to the slower anaerobic treatment  processes.  Due  to its low operation  and maintenance  costs, use of aerobic waste  water treatment  as a reductive  medium is getting increased  attention.  In addition,  this  is  very easy-to-obtain,  with  well  effectiveness  and  ability  for  degrading contaminants.  In  this article,  the  use  of aerobic  waste  water  treatment  technologies  to remove contaminants present in wastewater, which represent the main pollutants in wastewater, has been reviewed. The review concludes that suspended growth bioreactors are very efficient at low organic loading rates for treating wastewaters. Most of the biofilm reactors have a same level of COD removal.
