Feasibility of bioflocculation in a high-loaded membrane bioreactor for improved energy recovery from sewage
The feasibility of a high-loaded membrane bioreactor to improve methane recovery from sewage was investigated. Although the process needs further optimization, it already is feasible to recover at least 35% of the sewage COD. Important aspects for further research are the occurrence of membrane fouling, and the optimum process conditions for bioflocculation, i.e. the proper SRT/HRT ratio, ...

Particle counting as a tool to predict filterability in membrane bioreactors activated sludge?
Activated sludge quality is one of the major factors influencing flux decline in membrane bioreactors (MBRs). Sludge filterability is a recognized parameter to characterize the physical properties of activated sludge. Decrease in filterability is linked to a higher number of submicron particles. In our present research we studied whether particle counting techniques can be used to indicate ...

The cost of a small membrane bioreactor
The individual cost contributions to the mechanical components of a small membrane bioreactor (MBR) (100–2,500 m3/d flow capacity) are itemised and collated to generate overall capital and operating costs (CAPEX and OPEX) as a function of size. The outcomes are compared to those from previously published detailed cost studies provided for both very small containerised plants (<40 m3/day ...

Performance of a MBR for the treatment of blackwater
The paper describes the experience gained in operating a membrane bioreactor (MBR) for the treatment of blackwater. Beside a complete characterization of blackwater, operational conditions and removal efficiency concerning parameters such as COD, BOD5, nitrogen and phosphorus as well as microbiological parameters were determined. Furthermore the membrane performance was investigated. The results ...

Dye wastewater treatment by using ceramic membrane bioreactor
Performance of a Micro-filtration Membrane Bioreactor (MMBR) for treatment of dye wastewater was investigated. The experimental results indicated that the removal efficiency for COD, TOC and colour was 85%, 85-90% and 70%, respectively, the effluent COD was below 70 mgl−1 on average. Gel layer resistance of COD was 10%. Particle size distribution of sludge in MMBR was 1-150 μm, and the average ...

What is the Membrane Bioreactor Tank?
MBR membrane bioreactor is a new type of water treatment technology that combines membrane separation technology and activated sludge biotechnology. The MBR membrane module is placed in the membrane tank to replace the role of the secondary sedimentation tank in traditional water treatment. The treatment method is more efficient, and the effluent quality is better. In the operation of the entire ...

Application of a membrane bioreactor for winery wastewater treatment
Winery wastewaters are variable in nature and are hard to treat by means of the conventional activated sludge process because of the high organic loading associated with their production, especially during vintage. To face this situation, recently, membrane bioreactors have been widely applied to treat winery wastewaters. In this study, a full-scale membrane bioreactor treated some 110 m3/d of ...

MBR Operation
Although membrane bioreactor (MBR) technology has grown up to become a state-of-the-art in municipal wastewater treatment during the last decade, design, construction and operation of MBRs has not yet become a routine function. An insight into the practice of MBR technology will be available as a report at IWA Publishing by October 2010. ‘Operating Large-Scale Membrane ...

Evaluation of different configurations of hybrid membrane bioreactors for treatment of domestic wastewater
Four membrane bioreactors (MBRs) with the same dimensions were studied for 180 days: three hybrid growth membrane bioreactors with biofilm attached in different packing media and a conventional MBR (C-MBR). The four MBRs had an identical membrane module of hollow fiber with a nominal porous diameter of 0.4 μm. The MBRs were: (1) a C-MBR; (2) a moving bed membrane bioreactor (MB-MBR), ...

Integrating activated sludge floc size information in MBR fouling modeling
Although studied extensively, modeling fouling phenomena in membrane bioreactors (MBRs) remains challenging. It has been well established that cake layer formation and pore blocking have a strong impact on the filtration performance but how to capture that in comprehensive models is not fully defined yet. Since it has been shown that bioflocculation characteristics of activated sludge have a ...

Membrane Bioreactor for the treatment of natural rubber wastewater
A membrane bioreactor was set up using two pieces of Kubota flat sheet membranes, with nominal pore size of 0.4 ∝m and a total effective area of 0.2 m²atex concentrate processing factory. A steady-state MLSS concentration was attained at 8500 mg/L during biomass acclimatisation. A critical flux of 0.01224 m³/m²h was determined using the flux step method, whereas an optimum ...

Study on enhanced biological phosphorus removal using membrane bioreactor at different sludge retention times
An enhanced biological phosphorus removal process coupled with membrane bioreactor was proposed. Four runs were operated at different Sludge Retention Times (SRTs) of 20, 30, 40 and 50 d. Although average phosphorus removal tended to drop with SRT, the total phosphorus removal over 85% could be still achieved if the SRT was maintained under 40 d. Phosphorus-content in the sludge increased with ...

Kinetic evaluation of nitrification performance in an immobilized cell membrane bioreactor
High rate membrane bioreactor (MBR) systems operated at extremely low sludge ages (superfast membrane bioreactors (SFMBRs)) are inefficient to achieve nitrogen removal, due to insufficient retention time for nitrifiers. Moreover, frequent chemical cleaning is required due to high biomass flux. This study aims to satisfy the nitrification in SFMBRs by using sponge as carriers, leading to the ...

Commissioning and operating submerged membrane bioreactors: a designer's perspective
Submerged Membrane Bioreactor (MBR) applications for wastewater treatment have taken off in recent years in New Zealand. From designer perspectives, the membrane modules replace the conventional secondary clarifier, thus eliminating solids settling issues and reducing plant footprint. This paper discusses the recent experiences of Harrison Grierson Consultants Limited designing and commissioning ...

Effect of low dosages of powdered activated carbon on membrane bioreactor performance
Previous research has demonstrated that powdered activated carbon (PAC), when applied at very low dosages and long SRTs, reduces membrane fouling in membrane bioreactors (MBRs). This effect was related to the formation of stronger sludge flocs, which are less sensitive to shear. In this contribution the long-term effect of PAC addition was studied by running two parallel MBRs on sewage. To one of ...
