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...
متن کاملModeling styrene-styrene interactions.
This study is the first step in the systematic investigation of substituted (carboxyl) polystyrene nanoparticles. Understanding the fundamental interactions between the p-carboxyl styrene monomers, where an ethyl group is used instead of a vinyl group (referenced, for convenience, as "p-carboxyl styrene"), provides the basic information needed to construct potentials for nanoparticles composed ...
متن کاملSkin absorption of toluene, styrene, and xylene by man.
We have investigated the skin absorption of liquid toluene and of solutions of toluene in water by the methods we used for ethylbenzene (Dutkiewicz and Tyras, I967). The absorption rate of liquid toluene was I4-23 mg./cm.2/hr in I0 estimations on nine subjects. Absorption of toluene from an aqueous solution was proportional to the concentration (Figure). For equal concentrations the rate was on...
متن کاملModelling the Steady State and Dynamic Conditions of a Biotrickling Filter Treating Styrene and Acetone in Air
The aim of this work was the study a trickling biofilter, where water was circulated throughout the bed. In the first steady state experiment, the packing materials used were 25mm Pall rings. The airflow rate was increased gradually and the concentration of styrene in the air stream was held constant. In the second experiment, 15mm Pall rings were used. In this case, the feed contained both sty...
متن کاملCo-treatment of H2S and toluene in a biotrickling filter
Biological treatment is an emerging technology for the treatment of publicly owned treatment works (POTWs) off-gases. Most of POTWs off-gases contain H2S and a wide range of volatile organic compounds (VOCs). Since co-treatment of odors and VOCs in biotrickling filters is a relatively unexplored area, the simultaneous biotreatment of H2S and toluene (as the model VOC) was investigated. The expe...
