Bioremediation for Waste Water Treatment

Cleanergis is working on "Wastewater Treatment systems" that rely on microbes to perform the function of the breakdown of Industrial influents. These microbes are provided to the effluents either in along with a matrix, or as a biofilm, in treatment plants and holding tanks. They digest the solids and breakdown various compounds. One of the technologies that has been developed and field trials are carried out is on cleaning the Mollases Spent Wash (MSW).

The most damaging effect of MSW on a stream is caused by high concentration of readily decomposable organic matter. Soluble and suspended organic matters present in MSW, results in high BOD and COD thus creating a foul smell. This further promotes eutrophication (dense growth of weeds and dead organic matter) of the water body and can render the stream totally unfit for propagating fish life, for drinking purpose, personal hygiene, recreation and other objectives. MSW, when drained into a water source, make it susceptible for the propagation of harmful microbes resulting in water borne diseases. The intention of the technologies that would be jointly developed is to provide a solution to ultimately provide a viable method to create biofuels or manure from the MSW resource. in consequence providing economic viability and also provide additional job opportunities in the lower strata of the rural sector.
The proposed work is summarized as follows: It covers a novel technology developed by Cleanergis Biosciences Pvt. Ltd., and awarded at a competitive forum as an indigenous technology for waste water treatment supporting a social cause (Molasses spent wash treatment to algal biofuels, India Innovation Growth Program 2015,

In this technology, ways have been elaborated, especially using microbiological methods for decolorization and detoxification of MSW. Also, it can be demonstrated that algae grow on treated MSW. This technology has to be further improvised, and demonstrated in a scale-up scenario and economically important algae need to be grown on the treated MSW. We shall also be studying the membranes commercially available for making of the biofilms and efficient adherence of the microbes, and subsequently decolorization.
The approach that we are proposing is a step 1 of the treatment of MSW. Further to this treatment, the treated effluents shall also be processed by “Wetland system technology” . The Wetland System technologies have been used in waste-water treatment elsewhere, and Cleanergis is deploying this technology on one of its partner sites. The major outcome of implementation of the technologies is to get clean, odorless and safe water that can be used for agriculture or which can be disposed-off to the river/stream.
