  • Biofilm carriers / MBBR carrier media and their respective diffusion depth

    Within the biological wastewater treatment sector, it can increasingly be observed that biofilm carriers are applied in so-called Moving Bed Biofilm Reactors (MBBR). Thereby, the MBBR process is not only used to great success for the purification of domestic sewage but also in the sector of industrial wastewater and aquaculture systems. The availability of high-performance ...

  • Treatment of municipal sewage by Biological Aerated Filter (BAF) using burned clay pellet as media

    The high-strength municipal sewage was treated by the two-stage Biological Aerated Filter (BAF) pilot system with microorganism carrier of burned clay pellet. The effects of hydraulic loading rate, aeration ratio, overloading, backwashing and the height of media on the performance of BAF were investigated. In higher hydraulic loading and lower ratio of aeration, the two-stage BAF may decrease ...

  • Practical Applications of Static Low Density Media Filters for Use in the Treatment of Domestic Wastewater

    ABSTRACTIn the treatment of domestic wastewater, both biological and physical contaminant removal mechanisms must occur to facilitate compliance with NPDES permit discharge requirements. Static low density media (SLDM) filters can be used to perform both of these duties allowing for the consolidation of various unit operations into one component. Previous studies have shown that both organic and ...

  • Energy, cost and design aspects of coarse- and fine-bubble aeration systems in the MBBR IFAS process

    With the MBBR IFAS (moving bed biofilm reactor integrated fixed-film activated sludge) process, the biomass required for biological wastewater treatment is either suspended or fixed on free-moving plastic carriers in the reactor. Coarse- or fine-bubble aeration systems are used in the MBBR IFAS process. In this study, the oxygen transfer efficiency (OTE) of a coarse-bubble aeration system was ...

  • Fixed vs. Moving Bed Systems: Basin Geometry

    Aeration basins can have length to width (L:W) ratios varying from 1:1 (square) to over 30:1 (plug flow). The L:W ratio of an aeration basin directly impacts both the physical installation and biological performance of a submerged fixed-film system. Physical Installation Moving bed biomass carriers are free to move about the aeration basin. The aeration system provides energy to ...

  • Yucaipa, CA - case study

    The Challenge - Upgrade In 2007 the Yucaipa Valley Water District in Yucaipa, CA upgraded their Activated Sludge treatment plant to a Kruger AnoxKaldnes Biofilm + Activated Sludge (HYBAS) process. The plant expansion was driven by an increase in hydraulic loading and a new Total Inorganic Nitrogen Limit that was lowered from 10 mg/L to 6 mg/L. Process Solution The process flow scheme includes ...

  • Synergistic application of advanced primary and secondary wastewater treatment systems

    Published in Water and Waste Digest membrane issue, November 2008 Miroslav Colic; Chief Scientist, Clean Water Technology Inc., Los Angeles, CA To be published in Water and Waste Digest later this year The increased regulatory pressures and demand for reused water stimulated development of several new wastewater technologies in the last decade. Advanced treatment systems are ...

  • Biofiltration systems for the treatment of waste gas from industrial plants

    Bord na Móna Environmental Ltd have considerable experience in the field of biological air filtration (600 installations). Initially, the majority of installations were on Municipal and Industrial Wastewater applications. This was quickly followed by Municipal Solid Waste, an application Bord na Móna jointly developed with its Italian partners Air Clean srl. Since 2000, Bord na Móna have ...

  • Municipal: Wickford, USA

    The Challenge The existing wastewater treatment system at the North Cove development in Wickford, RI could not nitrify and denitrify in winter conditions. The system also had difficulty maintaining nitrification with warmer wastewater temperatures. The existing system consists of numerous septic tanks that receive wastewater (black and gray water) from residential buildings, discharging ...
