An adapted bioactive foamed emulsion bioreactor for the treatment of benzene vapor has been developed. In this reactor, bed clogging was resolved by bioactive foam as a substitute of packing bed for interfacial contact of liquid to gaseous phase. The pollutant solubility has been increased using biocompatible organic phase in liquid phase and this reactor can be applied for higher inlet benzene...

Biodegradation of chloroform along with a mixture of VOCs (methanol, ethanol, acetone and toluene) commonly found in pharmaceutical emissions using a biotrickling filter (BTF) was evaluated. The performance of the BTF was evaluated for both steady and transient conditions, for different inlet loading rates (ILR), empty bed residence time (EBRT) and inlet chloroform concentrations. Among the VOC...

alpha-Pinene biodegradation was evaluated in mesophilic and thermophilic biotrickling filters. The potential of silicone oil for enhancing the removal was evaluated too, at both temperatures. Performance was studied at empty bed residence times between 60 and 14s, and concentrations of 0.06-38.84 gm(-3), with or without silicone oil. Efficiency decreased as the pollutant concentration was incre...

Particle size, pH and Fe(III) ions affect the process of bioleaching of copper from chalcopyrite ores. In the study presented herein a copper sulfide ore was subjected to bioleaching process using a mixed microbial consortium obtained from a biotrickling filter treating high loads of H2S at different mineral particle size, distinct medium pH and various additional Fe(III) ion concentrations as ...

A Sporothrix variecibatus-inoculated biotrickling filter (BTF) was examined for styrene removal, without and with the addition of silicone oil, at different empty bed residence times. The highest elimination capacities (ECs) were 172.8 (without silicone oil) and 670 g m(-3)h(-1) (with silicone oil), respectively, corresponding to a 4-fold improvement in presence of oil. The addition of silicone...

Ex-situ biomethanation in a biotrickling filter is being developed as robust technology for the conversion of CO2 to CH4 using H2 generated from renewable power. The uses hydrogenotrophic methanogens biofilm catalyst and optimum supply nutrients imperative stable long-term operation. In this study, essential were highlighted along with systemic investigation nutrient methods. results showed tha...
