N2 - The effect of rate of mixture of methanol to hexane and pH on trickle-bed-air-biofilters (TBAB) performance for removal of n-hexane was studied. Flow switching with stagnation in the TBAB was a good tool to enhance the performance for low yield micro organism. Weekly backwashing was the best biomass control strategy for high yield micro organisms as in the case of methanol. Changing the nutrient buffer from pH 7 to acidic pH influenced the performance of the TBAB significantly. The presence of hydrophilic compound, e.g., methanol, had a positive impact on the degradation of n-hexane for loading rates of n-hexane below 13.2 g/cu m-hr. This is an abstract of a paper presented at the 104th AWMA Annual Conference and Exhibition 2011 (Orlando, FL 6/21-24/2011).
