Performance of a trickling filter for nitrogen and phosphorous removal with synthetic brewery wastewater in trickling filter biofilm
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...
متن کاملTrickling filter and trickling filter-suspended growth process design and operation: a state-of-the-art review.
The modern trickling filter typically includes the following major components: (1) rotary distributors with speed control; (2) modular plastic media (typically cross-flow media unless the bioreactor is treating high-strength wastewater, which warrants the use of vertical-flow media); (3) a mechanical aeration system (that consists of air distribution piping and low-pressure fans); (4) influent/...
متن کاملBiodegradation of toluene in a trickling filter
A trickling ®lter packed with PVC 16 mm Raschig rings was used to study the degradation of toluene in a polluted air stream, by means of a bacterial bio®lm of Pseudomonas putida ATCC 17484. A polluted stream was simulated by blending air with a controlled amount of toluene. The mixing was accomplished in a special mixing chamber designed for that purpose. Induction of the enzymes of the toluene...
متن کاملEnhanced nitrogen removal in trickling filter plants.
The Beaudesert Sewage Treatment Plant (STP), originally built in 1966 and augmented in 1977, is a typical biological trickling filter (TF) STP comprising primary sedimentation tanks (PSTs), TFs and humus tanks. The plant, despite not originally being designed for nitrogen removal, has been consistently achieving over 60% total nitrogen reduction and low effluent ammonium concentration of less t...
متن کاملMonitoring and modelling a pilot-scale trickling filter using on-line off-gas analysis
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...
