Volatile silicon compounds present in the biogas of anaerobic digesters can cause severe problems energy recovery systems, inducing costly damages. Herein, microbial community a lab-scale biotrickling filter (BTF) was studied while testing its biodegradation capacity on octamethylcyclotetrasiloxane (D4) and decamethylcyclopentasiloxane (D5), presence toluene, limonene hexane. The reactor perfor...

Biotrickling filters are one of the most widely used biological technologies to perform biogas desulfurization. Their industrial application has been hampered due difficulty achieve a robust and reliable operation this bioreactor. Specifically, biotrickling process performance is affected mostly by fluctuations in hydrogen sulfide (H2S) loading rate changes gas inlet concentration or volumetric...

Abstract Biotrickling filters are one of the most effective methods air bio-purification, this bioremediation process if high efficiency in pollution reduction. It is an eco-friendly and economically viable. The technology biotrickling includes Compact Trickle Bed Bioreactors (CTBB), which currently used increasingly wide range. aim work will be objective assessment implementation potential CTB...

Gaseous dimethyl sulphide (DMS) was eliminated in a biotrickling filter with Thiobacillus thioparus grown in polyurethane foam cubes as carrier material. The temperature, pH and empty bed residence time of the gas were maintained at 30 degrees C, 7.0 and 40 s, respectively. In the first 45 days, DMS loads of around 2.0 gDMS m(-3) h(-1) were fed to the BTF to adapt T. thioparus to DMS consumptio...
