In the fall of 2008, Johnstown, PA installed 32 BioWeb modules in their existing 12 MGD pure oxygen wastewater treatment plant. The plant needed to reduce the clarifier’s solids loading to bring the plant into compliance with their solids effluent limit. The BioWeb system provides additional fixed biomass, allowing the suspended biomass in the system to be reduced, improving the system stability and performance by reducing the clarifier solids loading.
Mr. Frank D’Ettorre of the Johnstown Redevelopment Authority said “Our original estimate for accomplishing our goals was over two and a half million dollars. With Entex’s cost-effective technology, we were able to save our ratepayers almost half the original estimate. And, with Entex’s system, the construction costs and implementation time was dramatically reduced.”
