چکیده

The effects of Tween-20 and Zn(II) on ethylbenzene removal were evaluated using two biotrickling filters (BTFs), BTF1 and BTF2. Only BTF1 was fed with Tween-20 and Zn(II). Results show that ethylbenzene removal decreased from 94% to 69% for BTF1 and from 74% to 54% for BTF2 with increased organic loading from 64.8 to 189.0 g ethylbenzene/(m³·hr) at EBRT of 40 sec. The effect of EBRT (60-15 sec) at a constant ethylbenzene inlet concentration was more significant than that of EBRT (30-10 sec) at a constant organic loading. Biomass accumulation rate within packing media was reduced significantly.

Removal of H2S from Synthetic Waste Gas Streams Using a Biotrickling Filter

The removal of hydrogen sulfide (H2S) from airstreams was studied in a biotrickling filter packed with porous lava as a carrier of Thiobacillus thioparus (DSM5368) with counter current flows of the air and liquid streams. The effect of operating parameters on biotrickling filter performance was studied. Experiments were performed at different empty bed residence times (9-60 sec), and...

Innovative Experimental Setup for the Parallel Operation of Multiple Bench Scale Biotrickling Filters for Waste Air Treatment

A new concept of periodically rotating biotrickling filters was developed for parallel operation of multiple bench scale biotrickling filters without the requirement for expensive equipment such as liquid recycle pumps and air flow regulation. The performance of 20 identically operated rotating biotrickling filters was reproducible with an average toluene elimination capacity of 79.4 g m h (sta...

Removal of benzene, toluene, xylene and styrene by biotrickling filters and identification of their interactions

Biotrickling filters (BTFs) are becoming very potential means to purify waste gases containing multiple VOC components, but the removal of the waste gases by BTF has been a major challenge due to the extremely complicated interactions among the components. Four biotrickling filters packed with polyurethane foam were employed to identify the interactions among four aromatic compounds (benzene, t...

The control of mercury vapor using biotrickling filters.

The feasibility of using biotrickling filters for the removal of mercury vapor from simulated flue gases was evaluated. The experiments were carried out in laboratory-scale biotrickling filters with various mixed cultures naturally attached on a polyurethane foam packing. Sulfur oxidizing bacteria, toluene degraders and denitrifiers were used and compared for their ability to remove Hg 0 vapor....

An Environmentally Friendly Method for Controlling Biomass in Biotrickling Filters for Air Pollution Control

Biomass accumulation is a major obstacle for long-term, stable operation of biotrickling filters treating high loadings of volatile organic compounds (VOCs). Clogging reduces pollutant removal and increases the pressure drop in biotrickling filters. Several options exist to remove excess biomass or to slow down the accumulation rate, but so far none has succeeded in combining a high VOC removal...
