| Abstract: | "Uneven distribution and excess accumulation of biomass within gas phase biofilters often result in operational problems such as clogging, channeling, and excessive head loss within biofilter beds, and consequently, the deterioration of performance. In this paper, the characteristics, mechanisms, and patterns of biomass accumulation in gas biofiltration were reviewed, and models for biomass accumulation were also summarized. Strategies for excess biomass control in gas biofiltration, categorized into either physical, chemical, or biological methods were also discussed, with improvements in design and operation of biofilters. Combinations of these approaches are usually necessary in order to maintain a reasonably even distribution and to minimize the accumulation of biomass in gas biofilters" |
