Innovation Detail

Profile
Innovator Mr. Moxad Pinakin  Thaker hails from Ahmedabad district of  Gujarat.

Purpose
In 2004, when Moxad was in the eighth standard, his teacher asked the class to participate in an upcoming Science fair with a novel idea. It rained heavily that day as Moxad was returning home. The roads were filled with water and it became very difficult for him to pedal his bicycle. This made him wonder if the energy of drainage water could be converted into electrical energy and felt that if this could be done, it could help solve the electricity problem of India. He worked on a comprehensive idea of using sewage to do many things including the generation of electricity and designed a scaled-down working model

In his design, valves and sensors are located at each junction node for control and calibration. The sewage water is first filtered at the source so that solid waste is separated and is used for biogas while the filtered water is used to run a turbine coupled with a generator to produce electrical energy and the water flowing out is partly issued for drip irrigation and partly for recharging the groundwater. The novelty of this idea lies in using the sewage water for multiple critical needs, all integrated into a multi-stage flow. The electricity thus generated can be used directly for supplying to and can be stored as well. The filtered water can also be purified by a solar-based system and used as portable water. Conventionally, sewage waste is used for direct charging of biogas plants. 

Benefits
Easy to use, affordable, filtration removes solids and concentrates the degradable material, which in turn increases gas production as well as methane content.
