Startup strategies for mainstream anammox polishing in moving bed biofilm reactors
Water Environment Research, 2022AbstractThis study evaluated startup strategies for mainstream polishing anammox moving bed biofilm reactors (MBBRs) without anammox bacterial (AMX) biomass inoculation. Two types of startups were tested: anammox only (no external carbon addition) and partial denitrification/anammox (PdNA) with glycerol addition.

Nitrification of municipal wastewater in moving‐bed biofilm reactors
Water Environment Research, 1995A moving‐bed biofilm reactor has been developed, where the biofilm grows on small, free‐floating plastic elements with a large surface area and a density slightly less than 1.0 g/cm3. Nitrification of preprecipitated wastewater in a once‐through system and raw wastewater in a recycled system with predenitrification has been studied in a pilot plant ...

Understanding of biofilm ecosystem in Moving Bed Biofilm Reactors for wastewater treatment
2022Microbial biofilms are widespread in the natural and engineered ecosystems where they perform essential ecological functions. Biofilm-based technologies are widely used in wastewater treatment plants, especially the Moving Bed Biofilm Reactor (MBBR) technology. In MBBRs, biofilms grow on the plastic carriers in aerated tanks.

Design and operations of the Kaldnes moving bed biofilm reactors
Aquacultural Engineering, 2006The moving bed biofilm reactor (MBBR) was developed in Norway in the late 1980s and early 1990s. It is covered by several patents and has been a huge success world-wide for treatment of municipal and industrial wastewaters. In addition, MBBRs have been successfully used for biological treatment of drinking water as well as for water treatment in fish ...

Biodegradation of tetracycline antibiotics in A/O moving-bed biofilm reactor systems
Bioprocess and Biosystems Engineering, 2017An anaerobic/aerobic moving-bed biofilm (A/O-MBBR) reactor system was constructed, and the treatment efficiency of aqueous antibiotics in wastewater was investigated. The effects of antibiotics on the microbial communities in the A/O-MBBR were also investigated.

Moving Bed Biofilm Reactor Technology: Process Applications, Design, and Performance
Water Environment Research, 2011The moving bed biofilm reactor (MBBR) can operate as a 2‐ (anoxic) or 3‐(aerobic) phase system with buoyant free‐moving plastic biofilm carriers. These systems can be used for municipal and industrial wastewater treatment, aquaculture, potable water denitrification, and, in roughing, secondary, tertiary, and sidestream applications. The system includes

Measuring and modeling the oxygen profile in a nitrifying Moving Bed Biofilm Reactor
Mathematical Biosciences, 2010In this paper we determine the oxygen profile in a biofilm on suspended carriers in two ways: firstly by microelectrode measurements and secondly by a simple mathematical model. The Moving Bed Biofilm Reactor is well-established for wastewater treatment where bacteria grow as a biofilm on the protective surfaces of suspended carriers.

[Experiment study on carriers in moving bed biofilm reactor].
Huan jing ke xue= Huanjing kexue, 2008Two methods of mixture modified and corona discharge were used to modify hydrophilic performance of the surface of the carriers. By mixture modified, the contact angle reduced from 108 degrees to 88 degrees, which showed carriers were hydrophilic; corona discharge could strengthen the effect and contact angle could reduce to 72 degrees further ...
