THE SITUATION

A major iron pipe foundry, located in a heavily populated urban setting, introduced a proprietary coating process to their soil pipe product line. Tar coated cast iron pipe is used in soil pipe installations to transport water and sewage because it is rugged and known for its excellent performance and long life. although this coating provided exceptional resistance to highly corrosive fluids typically found in industrial waste streams, it also produced asphalt smoke emissions that required specialized ventilation and abatement. Since asphalt smoke leaves a viscose residue that is non easily filtered out of the gas stream, the foundry needed to
install an improved ventilation system to remove the emissions.

THE SOLUTION

Our recommendation was a design-build-install solution that included our patented fiber-bed filters. The complexity of this project required multiple components to be designed and constructed from several locations and integrated into the foundry's process line. Our fiberbed filtration technology was selected as the mode of abatement because of the extremely high efficiency of this filter media for this type of environment.

THE RESULT

Engineers and craftsmen from several locations, worked together seamlessly to fabricate hoods, ductwork, four large housing, and candle-style fiber-bed filters. The result was a highly effective filtration of smoke emissions from the foundry and protection of the surrounding urban environment. Overall, this was a successful project in terms of customer satisfaction, project management and project profitability.
