Membrane bioreactor (MBR) is the combination of a membrane process like microfiltration or ultrafiltration with a suspended growth bioreactor, and is now widely used for municipal and industrial wastewater treatment.
MBR effectively uses the membrane to intercept the active micro-organism, which greatly increase the wastewater treatment capacity and improve the produced water quality.
Deals with what is activated sludge, mechanisms and kinetics of treatment, design of activated sludge process, secondary clarifiers and their design and bulking sludge, raising sludge and foaming of ASP.
Green Method Engineering (GME) is a reputed wastewater management company in Kerala who uses the advanced purification technology like MBBR for the wastewater treatment.

The heart of the fermentation or bioprocess technology is the Fermentor or Bioreactor. A bioreactor is basically a device in which the organisms are cultivated to form the desired products. it is a containment system designed to give right environment for optimal growth and metabolic activity of the organism.
A fermentor usually refers to the containment system for the cultivation of prokaryotic cells, while a bioreactor grows the eukaryotic cells (mammalian, insect cells, etc).

MBR (Membrane Bioreactor) STP is proven excellent sewage treatment solution combined with best technologiesi= including immersed membrane filtration systems and biological that enhances biological treatment.
SBR-process (Sequencing-Batch-Reactor) is the combination of the procedural functions “Aeration” and “Clarification” in one reaction tank. Here from a stable and flexible process flow results. Furthermore the SBR-process enables a compact plant design and a minimization of the investment costs. Because of the flexible plant geometry (tanks with circular, quadratic or rectangular footprint) SBR-wastewater treatment plants of w-wwt can be simply realized also under hindered project conditions (tourism areas, recreation centers, tower buildings etc.).
Biological Nutrient Removal (BNR) is a process used for nitrogen and phosphorus removal from wastewater before it is discharged into surface or ground water.To control eutrophication in receiving water bodies, biological nutrient removal (BNR) of nitrogen and phosphorus has been widely used in wastewater treatment practice, both for the upgrade of existing wastewater treatment facilities and the design of new facilities.

An Overview of Membrane Bioreactors for Anaerobic Treatment of WastewatersAM Publications
Application of Anaerobic Membrane Bioreactor (AnMBR) for wastewater treatment could be an attractive alternative to
recover energy in terms of biogas. In recent years, researchers have shown that AnMBRs can be used to produce methane from
synthetic wastewater. Studies were conducted in the laboratory scale anaerobic Membrane Bioreactor for treatment of synthetic
wastewater at different organic loading rates, under thermophillic and mesophilic conditions and ranging membrane flux. These
AnMBRs performed well for COD and BOD removal from the wastewater, demonstrating the effectiveness of this device for
wastewater treatment with COD and BOD removal efficiency above 90%. Results show that the application of anaerobic
membrane bioreactors is an efficient way to retain specific bacteria that can be a key for the treatment of wastewaters under
extreme conditions. The latter would enable their application to a wide range of industrial processes with the purpose of water
recycling. The challenge for future research is finding the optimum operational conditions to control the cake layer formation,
enhancing membrane performance and reducing the membrane area requirements. This will increase the economic feasibility of
AnMBRs, enabling its full scale application. The performance of the AnMBRs as reported in literature with different substrates,
membrane fouling issues and different membrane rector configurations are presented in this paper.

2. Contents Membrane Bioreactor (MBR) systems process outline Reasons for using MBR as an alternative to Activated Sludge Challenges to address: e.g. membrane fouling and stability Latest Research Further Work Summary
3. MBR: The Process Combination of membrane technology in a bioreactor and a biological stage => led to three generic types of MBR First type = separation and retention of solids Second type = bubble-less aeration within the bioreactor Third type = extraction of priority organic pollutants from industrial wastewaters
4. MBR: The Process Raw sewage from equalization/holding tank passes through fine screens to remove substances that may clog or scratch membrane before entering MBR facilities Membrane modules immersed inside aerobic tank where organic contents (BOD) in sewage is biologically degraded by activated sludge MLSS concentration in MBR sys = 10-20 g/l compared to 3-4 g/l in conventional AS thus 30% lower retention time compared to conventional systems Membranes separate solids from liquids in filtration process Pore size of membranes: 0.1µm, not only SS are removed but also bacteria such as coliform bacteria Immersed membrane filtration process eliminates requirement for gravity sedimentation tank/clarifier required by conventional ASS. By recirculating MLSS from aerobic to anoxic tanks, nitrate content removed Additional coagulant or flocculant dosing can be used for phosphorus removal Courtesy of Aquatech Pte Ltd
5. MBR Configurations Two Types: External and Internal External – Mixed liquor filtered under pressure in specific membrane module Internal or Submerged – Filtration in an aerated basin by suction to remove effluent
7. Issues: Membrane Fouling External modules can avoid fouling by carrying out tangential filtration especially when effluent is concentrated There may be a higher cost – this is justified! Necessary in such cases that shear stress on bioflocs is controlled, external membranes have high shear stress due to high recycle flow ratios
8. Why MBR over activated sludge? Traditional secondary clarifier replaced by membrane module. This module is more compact and quality of rejected water depends on changes in sludge settling velocities MBR allows the biomass concentrations to be higher than for traditional plants (20-30 g/l)
9. Latest Research Combination of MBR and NF/RO membranes for indirect potable water reuse applications (Abdulhakeem Ali Alturkiet al., 2010) Membrane bioreactor in water treatment (G. Wen et al., 2010) Novel Anaerobic MBR technology for low cost methane production: pilot wastewater project 2010 proved a success at Ken’s Foods WWTP in MA, USA
10. Further Work More indepth study of membranes: MBR or integrated/combined systems approach eg MBR + NF/RO Need to study membrane fouling further – establish better understanding for fouling process, identify which materials under what conditions (T, P and pH) will foul the least to optimize system design
11. Summary MBR presents an attractive alternative to conventional activated sludge (CAS) in treating wastewater MBR is a more robust technology with a small footprint and produces a higher quality effluent due to high removal efficiencies as a result of high retention time compared with CAS MBR can meet the increasingly stringent requirements for discharge of treated effluent placed on WWTP operators by environmental bodies like EA Research suggests that MBR has a lot of potential and is poised to be the next generation to wastewater treatment
