2 Two Innovative Technologies Unique Centrifugal Wastewater Filtration Technology Breakthrough Anaerobic Digester Technology © Copyright 2011, All Rights Reserved, Filtration Dynamics, Inc.

3 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 The FDI Advantages © Copyright 2011, All Rights Reserved, Filtration Dynamics, Inc.
