IIT boys draw power & water from sewage

The beauty of this is both purification and production of electricity.
“It was while working on microbes that can be used as purifying agents that Manoj Mandelia, a fourth year student of biotech engineering, stumbled upon the idea that if a bio cell can be developed to treat sewage water for use, it would solve one of the biggest problems of the present times. The idea is simple. The specially designed bio cell (LOCUS) will be set up in the form of a plant, through which the sewage water of a housing complex would be flowed in.
The genius of this invention which is awaiting patent lies in the design of the cell that will automatically grow millions of anaerobic bacteria that multiply through respiration. The bacteria clean up the sewage water and in the process generate free electrons. If harnessed, these electrons can generated electricity. The cell, at this stage, can clean up 50,000 litres of sewage water, about the amount generated by 100 flats in a day.
The water produced this way can be compared with that supplied provided by a civic body, the students say. “The purified water has been tested and has been certified to be clean and fit for household use. It is, however, not fit for drinking,” Mandelia explained. The IIT-Kgp team has even produced electricity with the bio cell. “A township of 100,000 people needs about 2.3 megawatts of electricity a day. It will be years before we reach that stage. But we have already been able to generate electricity. By next year, we aim to generate 350 units, enough to meet 50% of the demand of a 100-flat complex. When we say this we are not taking airconditioners into consideration,” said Prateek.” – Full Article Source
