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 ...

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 ...

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 carriers, ...

Moving Bed Biofilm Reactor (MBBR) in Wastewater Treatment
The Moving Bed Biofilm Reactor (MBBR) is another wastewater treatment technology. The major benefit of the MBBR process is a reduced footprint – an important major advantage when faced with space constraints. The Sequencing Batch Reactor process was discussed in a previous post – this article is a continuation of our series on the various wastewater treatment technology options ...

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 ...

Southwest landfill case study
The Problem: A landfill located in Texas was experiencing high concentrations of ammonia in the leachate from their domestic landfill. Compliance standards were becoming more stringent at the same time ammonia and BOD levels in the leachate stream were increasing in concentration. The Solution: After on‐site testing of a bioFAS High Rate Bio Filter (HRBF) process for a period of 1.5 years, ...

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 ...

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 ...

Hybrid activated sludge/biofilm process for the treatment of municipal wastewater in a cold climate region: a case study
A hybrid activated sludge/biofilm process was investigated for wastewater treatment in a cold climate region. This process, which contains both suspended biomass and biofilm, usually referred as IFAS process, is created by introducing plastic elements as biofilm carrier media into a conventional activated sludge reactor. In the present study, a hybrid process, composed of an activated sludge and ...

Methods for increasing the rate of anammox attachment in a sidestream deammonification MBBR
Deammonification (partial nitritation-anammox) is a proven process for the treatment of high-nitrogen waste streams, but long startup time is a known drawback of this technology. In a deammonification moving bed biofilm reactor (MBBR), startup time could potentially be decreased by increasing the attachment rate of anammox bacteria (AMX) on virgin plastic media. Previous studies have shown ...

Morphological examination of nitrifying biofilms in a moving bed biofilm reactor using optical coherence tomography and fluorescence in situ hybridization. Proceedings WEFTEC.16
Abstract: We present an imaging and image analysis approach to quantify both the overall morphology and the spatial distribution of nitrifying guilds in mixed-culture, nitrifying biofilms enriched on K1 carriers. For image acquisition we used optical coherence tomography to non-destructively visualize the three dimensional structure of entire internal cavities and fluorescent in situ ...
