Biological treatment is a promising alternative to conventional air-pollution control methods, but thus far biotreatment processes for odor control have always required much larger reactor volumes than chemical scrubbers. We converted an existing full-scale chemical scrubber to a biological trickling filter and showed that effective treatment of hydrogen sulfide (H2S) in the converted scrubber ...

The present study was conducted to evaluate the potential applicability of biological trickling filter system for the treatment of simulated textile wastewater containing reactive azo dyes with bacterial consortium under non-sterile conditions. The percentage decolorization for the treatment of wastewater containing structurally different dyes was found to be higher than 95% in all trials. The ...

The process characteristics of a pilot-scale trickling filter system were quantified by means of a measurement campaign with the use of off-gas analysis. A load shift experiment was conducted in which the influent load to the trickling filter system was suddenly decreased. To model the biodegradation in the filters, the model developed by Rauch et al. (1999) was used. This model was extended wi...

Article Type: Full Length Research Article The aim of this investigation was to confirm a trickling filter filled with gravel as an alternative biological process over conventional high cost treatment process with regard to nutrient reduction from brewery wastewater. Steady state evaluation of the trickling filter aerobic and anaerobic biofilm system for nutrient removal was made. The results o...

Plastic media trickling biofilter technology is being used on a pilot-scale to treat swine lagoon wastewater for use in a hydroponic greenhouse system. Two treatments of 9 filters each were installed to compare the treatment performance of commercially available BioballsTM and recycled soda six-pack rings and to verify a mathematical description of nitrification in a trickling filter. Determini...

Efforts to reduce phosphorus concentrations in aquaculture systems have mainly dealt with improving the bioavailability of phosphorus in fish feed. Once released into the culture water, phosphorus is generally left untreated and discharged with the effluent water. In the present study, results are presented on a prototype recirculating treatment system originally designed for removal of organic...
