RICHMOND, VA, Nov. 26, 2007 -- Degremont Technologies - Infilco recently was awarded two multimillion dollar contracts for the design and installation of Thermylis™ HTFB (High Temperature Fluid Bed) systems. In both cases, Thermylis™ was chosen as the most economic, efficient and environmentally friendly biosolids disposal method.

In the US, the City of Cincinnati, Ohio, has ordered 3 thermal oxidation lines to treat 262 dry US tons/day of sludge (238 metric tonnes) at their Mill Creek WWTP, while in Canada, the Duffin Creek WWTP will handle 230 dry US tons/day (210 metric tonnes) with 2 treatment lines for the City of Pickering, Ontario. The two contracts have a combined value of over $80 million.

In the thermal oxidation process, sludge is directly fed into a very hot fluidized sand bed where water is evaporated and organic materials are combusted, using high temperature to reduce the dewatered sludge by 93% to a much smaller quantity of inert ash (as low as 7%). The process is highly efficient, odor free and can generate useful heat for the production of process steam or electricity. The superheated steam generated at Duffin Creek will be used in a turbine to drive the fluidization air blower, thus replacing the 800 HP motor that would otherwise be needed. The "Green" technology is proven, safe and environmental friendly.

With 32 Thermylis™ systems in operation and under construction, Degremont Technologies secures its leadership position, with more fluid bed incineration systems in North America than any other supplier. With 2 units in operation and 2 more to be completed by 2009, the Lakeview WWTP in Canada remains the largest thermal oxidation plant in the world, with a capacity of 440 dry US tons/day (400 metric tonnes).

Focusing on municipal and industrial water markets, using proven technologies, Degremont Technologies (SUEZ) is the worldwide dedicated equipment branch of Degrémont (SUEZ).
