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 ...

Biofilm regeneration on carriers in MBBR used for vitamin C wastewater treatment

Methods were investigated for biofilm regeneration on carriers in a moving bed biofilm reactor used for vitamin C production wastewater treatment. Three ordinary chemical cleaning agents (hydrochloric acid, sodium hydroxide, and sodium hypochlorite) and physical drying were chosen for evaluation as methods for biofilm detachment. The results showed that these methods all had some degree of ...

$Organic removal activity in biofilm and suspended biomass fractions of MBBR systems$

Organic removal activity in biofilm and suspended biomass fractions of MBBR systems

The moving bed biofilm reactor (MBBR) wastewater treatment process is usually designed based on the assumption that all activity in the process occurs in the biofilm on the MBBR carriers, although there is always some active biomass in the bulk liquid due to biofilm sloughing and, sometimes, free-growing bacteria. In this study the removal of organic matter is evaluated in laboratory-scale MBBR ...

Modelling clogging and biofilm detachment in sponge carrier media

Sponge carrier media provide a large surface area for biofilm support; however, little information is known about how to model their dual nature as a moving bed and as porous media. To investigate the interaction of mass transfer and detachment with bio-clogging, a novel biofilm model framework was built based on individual-based modelling, and hydrodynamics were modelled using the lattice ...

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 ...

Rapid start-up of one-stage deammonification MBBR without addition of external inoculum

In recent years, the anammox process has emerged as a useful method for robust and efficient nitrogen removal in wastewater treatment plants (WWTPs). This paper evaluates a one-stage deammonification (nitritation and anammox) start-up using carrier material without using anammox inoculum. A continuous laboratory-scale process was followed by full-scale operation with reject water from the ...

Start-up of membrane bioreactor and hybrid moving bed biofilm reactor–membrane bioreactor: kinetic study

A hybrid moving bed biofilm reactor–membrane bioreactor (hybrid MBBR-MBR) system was studied as an alternative solution to conventional activated sludge processes and membrane bioreactors. This paper shows the results obtained from three laboratory-scale wastewater treatment plants working in parallel in the start-up and steady states. The first wastewater treatment plant was a MBR, the second ...

Development of a compact, cost effective, and energy efficient biofilm reactor for wastewater treatment and effluent reuse

Abstract The CFIC (Continuous Flow Intermittent Cleaning) biofilm reactor has been developed. It contains highly packed biofilm carriers to a degree that little movement of the carriers occurs in the reactor during normal operation. The process has continuous inflow to the bioreactor and intermittent cleaning, which removes excess biomass from the biofilm carriers. A large void volume ...

Quantification of kinetic parameters for heterotrophic bacteria via respirometry in a hybrid reactor

Over the last decade new technologies are emerging even more for wastewater treatment. Among the new technologies, a recent possible solution regards Moving Bed Biofilm Reactors (MBBRs) that represent an effective alternative to conventional processes. More specifically such systems consist in the introduction of plastic elements inside the aerobic reactor as carrier material for the growth of ...

Treatment of petroleum refinery wastewater using a sequential anaerobic–aerobic moving-bed biofilm reactor system based on suspended ceramsite

In this study, a novel suspended ceramsite was prepared, which has high strength, optimum density (close to water), and high porosity. The ceramsite was used to feed a moving-bed biofilm reactor (MBBR) system with an anaerobic–aerobic (A/O) arrangement to treat petroleum refinery wastewater for simultaneous removal of chemical oxygen demand (COD) and ammonium. The hydraulic retention time ...

Anammox moving bed biofilm reactor pilot at the 26th Ward wastewater treatment plants in Brooklyn, New York: start-up, biofilm population diversity and performance optimization

New York City Environmental Protection in conjunction with City College of New York assessed the application of the anammox process in the reject water treatment using a moving bed biofilm reactor (MBBR) located at the 26th Ward wastewater treatment plant, in Brooklyn, NY. The single-stage nitritation/anammox MBBR was seeded with activated sludge and consequently was enriched with its own ...
