Distribution and transformation of organophosphate esters in moving bed biofilm reactor

Environmental Geochemistry and Health, 2022
A moving bed biofilm reactor (MBBR) process in wastewater treatment plants (WWTPs) uses plastic carriers, called biofilm carrier, to increase their treatment efficiency. Biofilm carrier is made up of plastic, containing the OPEs as flame retardants or plasticizers, so OPEs in biofilm carrier are possible to release from WWTPs to the river.

Effect of Calcium on Moving‐Bed Biofilm Reactor Biofilms

Water Environment Research, 2011
The effect of calcium concentration on the biofilm structure, microbiology, and treatment performance was evaluated in a moving‐bed biofilm reactor. Three experiments were conducted in replicate laboratory‐scale reactors to determine if wastewater calcium is an important variable for the design and optimization of these reactors.

Numerical study of hydrodynamic characteristics in a moving bed biofilm reactor

Environmental Research, 2021
The 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, 1994
Abstract 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, 2015
This 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)

2017
In 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, 2016
This 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, 2017
Clindamycin 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.

Morphological image analysis of biofilm evolution with quantitative analysis in a moving bed biofilm reactor

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 Bioengineering
Sub-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).
