Wastewater-treatment System to Produce Electricity
Researchers in Scotland are hoping a new low-cost wastewater-treatment system for the developing world could also produce electricity.
A multi-disciplinary team led by Glasgow University has received £1 million from the EPSRC to create a bacteria-based system for treating waste in areas on the outskirts of cities that have poor or no sewage facilities.
Scientists will bio-engineer bacteria to break down large amounts of solid waste using anaerobic digestion (without oxygen) in a reactor based on existing technology used by distilleries and pharmaceutical companies.
They hope to be able to capture the gas from the process to generate electricity. Because the system would not produce other waste products, they also hope it could improve wastewater treatment in the developed world.
