TL;DR: An in situ trickling filter system, named Trickling Trench, is being used to treat biodegradable organic compounds at a site underlain by silt and clay.
Abstract: An in situ trickling filter system, named Trickling Trench, is being used to treat biodegradable organic compounds at a site underlain by silt and clay. This method provides the containment advantages of pump-and-treat remediation with the low-cost benefits of in situ bioremediation. A design method is presented using a conventional trickling filter analytical model with kinetic coefficients for various organic compounds calculated from published data. Performance monitoring data obtained from the Trickling Trench bioreactor are compared to design predictions.

TL;DR: In this article, a cross flow medium trickling filter was used to evaluate the performance of a synthetic wastewater in terms of its nitrification performance in three different hydraulic loading rates 5, 9 and 13␣m3/m2 · d under various influent ammonium concentrations.
Abstract: The nitrification performance of a synthetic wastewater was investigated in a cross flow medium trickling filter. The attachment of biomass on packing medium was studied. The reactor was operated continuously for three different hydraulic loading rates 5, 9 and 13␣m3/m2 · d under various influent ammonium concentrations. The maximum specific surface nitrification rate was about 1.21 g/m2 · d. There was a good agreement between actual and predicted alkalinity consumption. The ammonium conversion along the filter depth was also investigated. The external surface of the nitrifying biofilm was captured by scanning electron microscope. The results are found to be satisfactory.

TL;DR: In this paper, the authors defined the removal rate of indicator microorganisms on various types of trickling filters with regard to the influence of magnetic stream and electric current passage, and the effectiveness of microorganism adsorption onto the media.
Abstract: The objective of this study was to define the removal rate of the indicator microorganisms on various types of trickling filters with regard to the influence of: magnetic stream and electric current passage, and the effectiveness of microorganism adsorption onto the media. The hydraulic loading in the first eight variants were changing, while variants 9-14 were peformed at a constant loading. The study results have indicated a positive influence of the extra energy sources, i. e. a magnetic stream and electric current on the process of indicatory microorganism removal from waste water.
