3 Objectives The objective of sewage treatment is to produce a disposable effluent without causing harm to the surrounding environment, and prevent pollution. Our objectives are all above + make the process more compact and economically feasible through production of fuel, electricity, heat, and fertilizer from the abundant renewable energy source - sewage sludge (SS).

4 What resources do we have? 53 million tones of sewage treated daily in the US (60% of all produced sewage) This contains 27,000 tones of biosolids with calorific value 12 MJ/kg If converted into electricity = 18,000 GWӿh per year Could provide electricity to 1.5 million people Renewable and growing energy source

5 What are we going to improve? Reduce de-watering expenses by 25-30% Use sewage sludge with 30% water content as a renewable feedstock for plasma gasification and syngas production with H2 yield by 35 % vol. Use syngas for energy efficient electricity and heat production 10 tones of sewage sludge will provide from 7,2 to 12 MWӿh of clean electricity + 15 to 19 MWӿh of heat daily Switch sewage treatment ideology from power consumption to power production Show new opportunities for sewage treatment

6 Simplified process flow diagram for a typical large-scale treatment plant

7 Technical aspects of the Demo Unit 10 tons of SS treatment per day Converts SS into syngas in a high efficient multistage plasma reactor with new RF plasma Up to 85% thermal efficiency Power production 3 to 5 times accedes power consumption SS could be blended with any in-situ hazardous liquids, including used motor and transformer oil, kitchen oil, etc. Could be used for animal waste treatment
