Abstract

Biological systems work best for the treatment of large volumes of off-gases that contain low concentrations of biodegradable contaminants. The effect of pH on Trickle Bed Air Biofilter (TBAB) performance for removal of a mixture of n-hexane and benzene mixed in a ratio of 1:3 was studied. The change in bacterial culture from bacteria to fungi did not have significant difference in the behavior of the TBAB for benzene removal, but it was crucial for n-hexane. Fungi utilization greatly enhanced the performance of n-hexane. Flow switching with stagnation for a period of 2 days/week in the TBAB was a good tool to enhance the performance. This strategy could replace backwashing for low yield micro organisms as in the case of n-hexane. This is an abstract of a paper presented at the 102nd AWMA Annual Conference (Detroit, MI 6/16-19/2009).
