Hydrogen sulfide and odor removal by field-scale biotrickling filters: Influence of seasonal variations of load and temperature

2012

Two biotrickling filters were set up at two wastewater treatment plants (WWTP) in The Netherlands to investigate their effectiveness for treatment of odorous waste gases from different sources. One biotrickling filter was installed at Nieuwe Waterweg WWTP in Hook of Holland to study the hydrogen sulfide removal from headworks waste air. The other reactor was installed at Harnaschpolder WWTP (treating wastewater of the city of The Hague) to remove mercaptans and other organic compounds (odor) coming from the emissions of the anaerobic tanks of the biological nutrient removal (BNR) activated sludge. The performance of both units showed a stable and highly efficient operation under seasonal va…

Biofiltration System for Purification of Composting Waste Gases

2006

The biofiltration technique for the purification of polluted air from composting facility volatile compounds was studied. Two different biowaste composting techniques were compared with regard to emission of NH3 and H2S. The ammonia removal was observed in aerobic phase of active composting period, respectively H2S in anaerobic phase. Biofiltration process was realized in modified solid- state fermentation system (SSF). The biodegradation of volatile compounds was investigated in one and two stage systems with inert packing material and hemoautotrofic microorganisms designed DN-1 (Pseudomonas sp.), DN-2 (Nitrisomonas sp.), DN-3 (Nitrobacter sp.) and DN-13 (Sarcina sp.) and Thiopharus-3. The…

Full-scale biotrickling filtration of volatile organic compounds from air emission in wood-coating activities

2012

BACKGROUND: Biotrickling filtration could be considered as a suitable and viable technology for controlling the industrial emissions of volatile organic compounds (VOCs) in waste gases. In this study, the performance of a full-scale biotrickling system, including a passively activated carbon-smoothing prefilter was investigated for the treatment of exhaust gases from two different paint spray sources at a furniture facility. RESULTS: The VOC profiles were uneven for both sources, but the second source was more irregular, with highly variable VOC loads. The plant was operated at empty bed residence times (EBRTs) between 20 and 100 s. The system was able to control the VOC emissions, so air t…
