In this study, the effect of inlet concentration pollutants, empty bed residence time (EBRT) and liquid recycling velocity on performance BTF was explored. The results showed best operating characteristics biotrickling filter for study were at an 500 mg/m3�Cthe EBRT 300s 25.46 m h-1. At condition, total removal efficiency pollutants can reach more than 90%. Among them, toluene ethylbenzene abov...

Abstract Acidic biotrickling filters (BTF) can be used for simultaneous removal of hydrogen sulfide (H2S) and siloxane from biogas. In this study, the performance a BTF under different acidic pH conditions was investigated. The profile H2S showed that 90% achieved during first 0.4 m height with down-flow Decamethylcyclopentasiloxane (D5) decreased 34.5% to 15.6% when increased 0.88 3.98. Furthe...

Biofiltration of hydrophobic and recalcitrant volatile organic compounds faces challenges, the bioaerosols sourced from biofiltration might cause secondary pollution. In this study, combination ultraviolet photodegradation biotrickling filtration (UV-BTF) was designed to treat gaseous cyclohexane, UV post-treatment (post-UV) further utilized for bioaerosol emissions management. Results showed t...
