Numerical study of hydrodynamic characteristics in a moving bed biofilm reactor
Environmental Research, 2021The moving bed biofilm reactor (MBBR) has certain advantages, such as high wastewater treatment efficiency, low maintenance and operating costs, and simple operation. It has emerged as a valuable option for small decentralized facilities. The filling ratio, aeration mode and aeration intensity are the main factors that affect the performance of MBBRs ...

Nitrification in a moving bed biofilm reactor
Water Research, 1994Abstract A new biofilm reactor, the moving bed reactor, was studied for nitrification purposes. The study was partly on laboratory-scale with a prepared water, and partly on pilot-scale with primary or secondary effluent as feed water. The experimental results showed that when alkalinity was in excess and there was no organic load, either the ...

Evaluating the effect of biofilm thickness on nitrification in moving bed biofilm reactors
Environmental Technology, 2015This study evaluates the effect of biofilm thickness on the nitrifying activity in moving bed biofilm reactors (MBBRs) in a controlled environment. In-depth understanding of biofilm properties in MBBRs and their effect on the overall treatment efficiency is the key to optimizing process stability and efficiency.

Moving Bed Biofilm Reactor (MBBR)
2017In recent years, an increasing interest in biofilm processes for the treatment of municipal and industrial wastewaters has been observed. One of the growing biofilm technologies is the Moving-bed Biofilm Reactor (MBBR), which has been successfully established in the market. A great number of large-scale wastewater treatment plants along with many other

Moving bed biofilm reactor to treat wastewater
International Journal of Environmental Science and Technology, 2016This review carries out a comparative study of advanced technologies to design, upgrade and rehabilitate wastewater treatment plants. The study analyzed the relevant researches in the last years about the moving bed biofilm reactor process with only attached biomass and with hybrid biomass, which combined attached and suspended growth; both could be ...

Transformation products of clindamycin in moving bed biofilm reactor (MBBR)
Water Research, 2017Clindamycin is widely prescribed for its ability to treat a number of common bacterial infections. Thus, clindamycin enters wastewater via human excretion or disposal of unused medication and widespread detection of pharmaceuticals in rivers proves the insufficiency of conventional wastewater treatment plants in removing clindamycin.

Science of The Total Environment, 2023
The quantitative analysis of biomass is essential for the research and application of moving bed biofilm reactors (MBBRs). However, the difficulty in measuring the attached growing biomass hinders the quantitative analysis of biofilm processes. In this study, a pilot-scale MBBR system was established to investigate biofilm evolution.

Modeling the Performance of an Anaerobic Moving Bed Biofilm Reactor
Biotechnology and BioengineeringSub-models representing transformation processes by microorganisms and hydrolases, a one-dimensional (1-D) biofilm, and a bioreactor were integrated to simulate organic-matter fermentation and methane (CH 4 ) production in an anaerobic moving bed biofilm reactor (AnMBBR).

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 ...
