GMD's CERT system controls emissions, significantly reduces exhaust volumes. (Technology in Action).

USER--Waupaca Foundry Plant #1, Waupaca, Wisconsin a producer of iron and ductile iron castings.

OPERATION--Cupola Emission Control System

PROBLEMS--Wet Scrubber discharge not meeting emission standards.

SOLUTION--Side stream at least 50% of the Cupola Exhaust to a GMD Cupola Emission Reduction and Treatment System (CERT) which includes GMD's High Temperature Off Gas Cooling and a GMD Flue Gas Cooler to cool the off gases, six (6) GMD Pulse Baghouses to filter the exhaust and GMD TETS[TM] to treat the baghouse dust to a non-hazardous condition and the [SO.sub.2] in the exhaust stream.

BENEFITS--Taking 60% of the total cupola exhaust load, the GMD CERT produced a reported emission rate of less than 0.003 gr./dscf, far below the proposed MACT rate for Cupolas and is approximately 1/16 of the emission rate of the wet scrubber with the reduced exhaust volume.
