||Validation of a recommended approach to recirculation of industrial exhaust air. Volume I

||The validity of the approach recomended in DHEW(NIOSH) Publication No.78-124 (CIS 79-85) was evaluated by studying its application in the design of new recirculation systems and in retroactive applications to existing systems. Recirculation of air contaminated with particles, mists, vapours and fumes using fabric filters, baghouses, scrubbers, electrostatic precipitators and carbon absorbers as air cleaning systems was studied in the context of spring grinding, hard chrome plating, dry cleaning, and welding and degreasing operations. The approach provides and appropriate framework for the design of recirculation systems and is of value in identifying and resolving problems of health and safety.
