TL;DR: In this article, an optimization method is used to determine the most economical design for biological trickling filters based on four different models, the Eckenfelder, the Galler-Gotaas, the National Research Council and the Upper Mississippi and Great Lakes Board.
Abstract: An optimization method is used to determine the most economical design for biological trickling filters based on four different models, the Eckenfelder, the Galler-Gotaas, the National Research Council and the Upper Mississippi and Great Lakes Board. Filter depth has the greatest influence on the most economical design with the Galler-Gotaas model, some influence in the Eckenfelder and NRC models and no influence in the Upper Mississippi and Great Lakes model.

TL;DR: In this article, the authors proposed a method for treating organic waste gases with a novel membrane biological trickling filter with the combination of separation of a gas membrane and a biochemical reactor.
Abstract: The invention relates to a method for treating organic waste gases with a novel membrane biological trickling filter With the combination of separation of a gas membrane and a biochemical reactor, organic pollutants in waste gases are purified through gas membrane mass transferring, anaerobic/anoxic biodegradation and aerobiotic biological degradation, the organic waste gas is fed into a membranebiological trickling filter reactor, a waste gas distribution module, a biological trickling filter module and a membrane biological reactor module are distributed in the membrane biological trickling filter reactor in a gas flowing direction; the biological trickling filter module and the membrane biological reactor module are connected with a biological liquid circulation module through circulation pipelines; the biological liquid circulation module is in charge of conveying and circulation of biological liquids of the biological trickling filter module and the membrane biological reactor module The method solves the defect that a conventional biological trickling filter method is low in common removal efficiency upon hydrophobic volatile organic compounds, also prevents membrane pollution problems caused by excessive multiplication of microorganisms, has the advantages of being small in floor space, high in purification efficiency, low in operation cost, and the like, and is applicable to treatment on multiple VOCs (Volatile Organic Compounds) organic waste gases

TL;DR: In this article, an approach to remove low concentration SO 2 using biological trickling filter was studied, and the results of preliminary experiment show that the optimum operating conditions are as the following: the concentration of SO 2 in influent gas is 500-1?000?mg/m~3, the gas flow is 0.1?m 3/h,circulated liquid flow is 15?L/h and pH is 1.0.
Abstract: An approach to remove low concentration SO_2 using biological trickling filter was studied.The results of preliminary experiment show that the optimum operating conditions are as the following:the concentration of SO_2 in influent gas is 500—1?000?mg/m~3,the gas flow is 0.1?m~3/h,circulated liquid flow is 15?L/h and pH is 1.0.When the gas flow is changed from 100?L/h to 300?L/h,the SO_2 removal efficiency decrease,from 86.4% to 73.2%,while the concentration of SO_2 in influent gas is about 2?500?mg/m~3,the SO_2 removal efficiency can arrive to 90%.
