Multi-Stage Dry Separator Midwest Air Products Co. Inc. Traverse City Mich.

The Enforcer III is a multiple- stage dry separator that uses mesh pads to remove hexavalent chro- mium from plating exhaust. A pump- ing station can be installed to period- ically rinse each of the mesh pad stages at programmed intervals and durations, typically for 15 to 30 sec. Frequent cleaning of the mesh pads keeps the separator clean and in- creases its life span. The counter- flow design, or trickle-down effect, minimizes floor space and allows a low daily effluent flow without sac- rificing retular cleansing. Mass emis- sions are as low as 0.00039 mg/a-hr. The separator can be modified to re- turn low volume effluent of chromic acid back to the plating bath.
