TL;DR: In this paper, the effect of temperature, hydraulics and pollutant loading on a full-scale trickling filter performance for simultaneous ammonium, iron, and manganese removal was studied.
Abstract: The effect of temperature, hydraulics and pollutant loading on a full-scale trickling filter performance for simultaneous ammonium, iron, and manganese removal was studied. Pollutant concentrations fluctuate sharply in raw well water, exceeding many times the maximum permitted limits. Measurements taken during the one-year continuous operation of the filter, as well as the 24 h experiments performed in various seasons, have shown a dependence of the pollutant removal efficiencies on temperature (8–28°C) and hydraulic loading (5–12 m3/h) shocks. However, in all environmental and operating conditions, high removal efficiencies were achieved for ammonium, iron and manganese maintaining final concentrations at the filter outlet to below EC parametric values.

TL;DR: Several combinations of additional aerobic volume and sludge bypass flowrate were found to successfully achieve both nitrogen and phosphorus removal, using the existing facilities without the need for new reactors neither implementing modifications that could put the trickling filters' physical integrity at risk.

TL;DR: It is illustrated that adopting low energy TF technologies can eliminate the requirement for more energy intensive alternatives, such as submerged aerated filters (SAF), while simultaneously improving nitrification robustness when compared with tertiary nitrification processes.
Abstract: The wastewater industry is under pressure to optimize performance of sewage treatment works (STW), while simultaneously reducing energy consumption. Using a process configuration selection matrix, this paper explores the practicability of placing a hypothetical cross flow structured plastic media (CFSP) trickling filter (TF) immediately ahead of an existing conventional trickling filter process (CTFP), without intermediate clarification. The viability of this configuration is subsequently demonstrated using an empirical multispecies TF model. This predicts the enhanced nitrification performance of the CTFP by simulating prior removals of biochemical oxygen demand (BOD). The model predictions propose that prior 50-80% BOD removals can allow for further reductions in effluent ammoniacal nitrogen (NH4-N) concentrations of 40-70%, respectively. This illustrates that adopting low energy TF technologies can eliminate the requirement for more energy intensive alternatives, such as submerged aerated filters (SAF). Moreover, this configuration maximizes the potential of existing assets, while simultaneously improving nitrification robustness when compared with tertiary nitrification processes.
