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).

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 GWh per year

Could provide electricity to 1.5 million people

Renewable and growing energy source

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 MWh of clean electricity + 15 to 19 MWh of heat daily

Switch sewage treatment ideology from power consumption to power production

Show new opportunities for sewage treatment

Technical aspects of the Demo Unit

10 tons of SS treatment per day

Converts SS into syngas in a high efficient multi-stage 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

Commercially Available Plasma Products

Plan A

Establish international network of potential

customers and regional technology providers

Raise funds through the Plasma Fund,

customers, private/government sources

Develop and build 1 to 3 Demonstration Plants

in 2016-2017

Perform field tests

Merge Sewage Gasifier with a gas turbine

Start mass production of 10-15 TPD units

Scale-up to 100 TPD

Worldwide technology commercialization

Conclusions

First of a kind plasma system for such an exotic

application

New vision of the waste water treatment

Highly efficient

Significant environmental impact

Huge marketing potential

Flexible feedstock any liquid, including animal waste, used motor and kitchen oil, hazardous hydrocarbons
