Biodesulfurization using biotrickling filters (BTFs) under anoxic conditions is a cost-effective method for biogas clean-up. To improve the performance of BTFs, microbial consortia from anaerobic pond swine farm (SW), denitrification tuna factory (DN), and UASB concentrated latex industry (LW) were immobilized on BTFs. In this study, efficiency BTFs with reduction H2S gas combined nitrate conta...

Hydrogen sulphide (H2S) and volatile methylsiloxanes (VMSs) are key pollutants from the point of view operators biogas plants. H2S poses corrosive hazards, while VMSs transform into difficult-to-remove deposits, reducing availability yield combustion equipment. This study provides a critical overview evaluation (so-called SWOT analysis) implemented promising methods to reduce content above in b...

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...

Ammonia emissions are found in a wide range of facilities such as wastewater treatment plants, composting pig houses, well the fertilizer, food and metallurgy industries. Effective management these is important for minimizing detrimental effects they can have on health environment. Physical-chemical (thermal oxidation, absorption, catalytic etc.) treatments most common techniques abatement ammo...
