The biofiltration method was used to treat the odor produced from the activated sludge thickener and sludge dehydrating unit of a municipal wastewater treatment plant in southern China.

The biofiltration and the biologic expanded bed techniques were adopted in succession to treat ammonia-contaminated gas streams, then the advantage and disadvantage of the two techniques were compared in detail, to overcome the shortage of the two techniques, a novel biological process for the treatment odors was established ,which was the result of the bi.
