  • Bissell Point, Missouri - Trickling Filter installations applications - Case Study

    Bissell Point, the largest wastewater treatment facility in Missouri, expanded their facility in the mid-1980s to provide secondary treatment. The goal of the upgrade was to select a reliable process that would achieve high-rate BOD removal. They opted for trickling filter technology and worked with Brentwood to install roughly 3 million cubic feet of plastic media in 6 towers. Nearly 25 years ...

  • Feasibility of UASB/trickling filter systems without final clarifiers for the treatment of domestic wastewater in small communities in Brazil

    The paper analyses the concept and performance of different configurations of compact UASB/TF systems, without the final clarification stage, in relation to the removal of organic matter. The experiments were carried out in two sets of UASB/TF systems operating without secondary clarifiers, as follows: (i) four shallow (2.50 m height) TFs, each one filled with a different packing material; and ...

  • Diversity and dynamics of ammonia-oxidizing bacterial communities in a sponge-based trickling filter treating effluent from a UASB reactor

    Changes in ammonia-oxidizing bacterial (AOB) population dynamics were examined in a new sponge-based trickling filter (TF) post-upflow anaerobic sludge blanket (UASB) reactor by denaturating gradient gel electrophoresis (DGGE), and these changes were linked to relevant components influencing nitrification (chemical oxygen demand (COD), nitrogen (N)). The sponge-based packing media caused strong ...

  • Performance of plastic- and sponge-based trickling filters treating effluents from an UASB reactor

    The paper compares the performance of two trickling filters (TFs) filled with plastic- or sponge-based packing media treating the effluent from an upflow anaerobic sludge blanket (UASB) reactor. The UASB reactor was operated with an organic loading rate (OLR) of 1.2 kgCOD m−3 d−1, and the OLR applied to the TFs was 0.30–0.65 kgCOD m−3 ...

  • Evaluation of Tire Derived Rubber Particles for Biofiltration Media

    ABSTRACTCurrently, on average, one tire is discarded in the U.S. for every man woman and child every year. While the reuse market for used tires has increased over the years to approximately 75%, there are still an estimated 2-3 billion used tires stockpiled in the U.S. Finding economical and sustainable end uses for this tire material is an ongoing challenge to environmental engineers and ...

  • Treatment of wastewater from a school in a decentralized filtration system by percolation over organic packing media

    Based on results obtained in the laboratory a WWTP composed of a septic tank and an aerated percolating filter packed with organic media was built for a school. The system can treat 18 m3 d−1 and was operated with a hydraulic loading rate of 0.078 (m3 m−2 d−1). For 360 days different operational conditions including start-up; stabilization; operation with aeration and non aeration; effect of ...

  • Army Truck Wash Depot case study

    The Problem: The Army Truck Wash Depot had a trickling filter that was not capable of handling the organic loading generated by heavy vehicle wash operation. The tricking filter was channeling the wastewater due to media that had been crushed by the weight of the biomass that could not be sloughed off. As a result, the ability to treat the wastewater for BOD ...
