The report gives results of a study extending an earlier project during which an investigation of the performance of packed-bed scrubbers for high-intensity rendering plant odors (5000 to 180,000 odor units) showed that, although in some cases the removal was as high as 99%, the average was only 85%. In this study, extensive performance data was obtained with an odor panel over a period of 8 weeks. Removal averaged 93% with three stages of sodium hypochlorite scrubbing even though each stage was designed to remove 99% of the odors based on its mass-transfer capacity. The results, fitted to a regression equation, showed that the important variables are the age of the solution and the relation of the inlet odor concentration to the previous history of exposure of the scrubbing solutions to high odor intensities. Chlorine concentration and pH also affect the results, and calcium hypochlorite is about 1.5 times more effective than sodium hypochlorite.
