Abstract: Odor control is a severe problem common to most wastewater operations particularly significant at urban treatment plants, gas and oil refineries, paper and pulp industries, etc. The most commonly reported odorous compound in POTW off-gases is hydrogen sulfide (H₂S) which has a very low odor threshold. These odorous emissions can cause a nuisance to adjacent populations and contribute significantly to atmospheric pollution. Waste gases have traditionally been treated using physicochemical processes, such as scrubbing, adsorption, condensation and oxidation, however biological treatment of waste gasses has gain support as an effective and economical option in the past few decades. Some studies have been done on biological systems to control of waste air containing H₂S, although no review on these systems have been reported in the literature. This study reviews available data regarding the performance of biological systems to treat off-gases containing H₂S.
