Energy from Wastewater

Two Innovative TechnologiesUnique Centrifugal Wastewater Filtration Technology

Breakthrough Anaerobic Digester Technology


Energy The largest energy utility cost of any city becomes a profit center A net energy advantage in excess of 3,000 kWh per million gallons

(MG) Wastewater treatment plants with flow rates of 5 million gallons per day

or less can become energy positive

Costs New facilities & upgrades at 50% of typical costs 25% reduction in operational costs

Size 80% less land required for treatment plants, recovering unused land Indoor capable, volume adjustable, and scalable to allow satellites

Operational Avoids the creation of sludge and its associated costs Isolates and concentrates energy latent organics

Time Converts organics to methane in minutes instead of days or weeks

Indoor Capable Scalable

Eliminate current electricity costs : 2,500 kWh/MG

Produce electricity @ : 1,400 kWh/MG

Consume electricity @ : – 750 kWh/MG

Sell excess electricity to the grid : 650 kWh/MG

Attain a net energy advantage : 3,150 kWh/MG

The Resource Recovery Plant Concept Will:


(~ 1,000 Population) processing 0.1 MGD

will realize a net energy advantage of 115,000 kWh annually.

(Equivalent to removing 91 tons of CO2 from the atmosphere)

(~ 10,000 Population) processing 1 MGD

will realize a net energy advantage of 1.15 million kWh annually.

(Equivalent to removing 910 tons of CO2 from the atmosphere)

(~ 50,000 Population) processing 5 MGD

will realize a net energy advantage of 5.75 million kWh annually.

(Equivalent to removing 4,550 tons of CO2 from the atmosphere)

Energy Advantage — Any City, U.S.A.


Energy The largest energy utility cost of any city becomes a profit center A net energy advantage in excess of 3,000 kWh per million gallons

(MG) Wastewater treatment plants with flow rates of 5 million gallons per day
