write a short on bioremediation in sewage treatment
Answers
Many Communities and Industries across the world are intensely exploring bioremediation as an important source to clean up waste water. Bioremediation mainly uses naturally occurring microorganisms and other aspects of the natural environment to treat the wastewater of its nutrients. This type of initiative provides an avenue to environmentally and economically sustainable treatment methods.
While a number of new Bioremediation methods are currently being used for sewage treatment of industrial waste water in sewage treatment plants (STP) and effluent treatment plants (ETP), these are very exclusive methods that depend on costly chemicals and heavy inputs of energy. It emphasize on sustainable wastewater treatment worldwide. The industries are very much interested on initiating a method that can be cheap and can provide a, long-term, sustainable solution for treatment of waste water and sewage treatment.
Waste water treatment and bioremediation is a cost effective process due to significant time and planning needed for successful treatment. Now- a-days there are modern wastewater treatment plants, which are highly technical, mechanized and expensive to build and maintain. In most of the under developed countries of the world, optional methods of sewage water and wastewater treatment are required. Sewage water stabilization ponds, lagoons, can provide an appropriate solution for wastewater treatment in developing countries and rural areas. Usually Algae is used for the process of bioremediation and waste water and for sewage treatment.
Algal biomass can be processed biologically or chemically, to produce high value products such as bioacetone, biodiesel, biomethane and biobutanol. Microalgae act as feedstock can also provide increased densities of carbohydrates, triacylglycerides and fatty acids that can be used to produce biodiesels and bio-fuels
