Study on Performance of Membrane Bioreactor (MBR) system at various temperatu...AM Publications
The study on performance of sidestream membrane bioreactor (MBR) was studied by varying temperature (30oC, 33oC and 40oC)
along with crossflow velocity (1m/s, 1.5m/s and 2 m/s).CFV and temperature had significant effect on performance of sidestream MBR.
Performance was studied by analysing COD removal (%), flux declination, Transmembrane pressure, mixed liquor suspended solid
concentration. Maximum COD removal was 93% is obtained at 30oC with CFV 1.5 m/s. Flux declination is large at 30oC as compared to flux
declination at 33oC and 40oC temperatures for all CFVs. Sludge production in terms of MLSS, is large at 30oC and minimum at 40oC. This
high concentration of MLSS is responsible for large COD removal as well as increased in membrane fouling which cause large flux
declination. It is observed that high CFV causes less flux declination tends to large permeate flux. By visual perception it is observed that at
higher temperature, bioreactor content was more turbid than at low temperature this means that, large bioflocs get segregated and cause fast
scouring on membrane surface, it resultsslow down of permeate flux declination. Selection parameter (SP) was used to optimize the
operational condition of MBR system. Largest value of SP was treated as optimum value for operation of sidestream MBR. Thus, condition T
= 33oC, CFV = 2 m/s gave highest SP value 27 lit/m2-hr, and may be recommended for treating wastewater of COD 1092 mg/lit. Comparison
of side stream MBR with submerged MBR system was carried out, and it is observed that sidestream MBR data is best suitable for waste
water treatment.

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.

Review of research on bio reactors used in wastewater ijsit 2.4.6IJSIT Editor
The review presented in this paper focuses on reactors used in wastewater treatment for bio
hydrogen production (e.g. batch reactors, complete mix reactors, plug flow reactors, bio-film reactors,
suspended reactors, upflow anaerobic sludge blanket reactor, anaerobic baffled reactors, upflow packed-bed
attached growth reactors, attached growth fluidized bed reactors, anaerobic sequencing batch reactor, hybrid
/ high rate reactors and membrane separation reactors. It is clear from the review that development of these
reactors can be considered a grown up research for which good design and scale-up guidelines are available
Biotechnology in Microbiology- includes the how microbial associations are worked out in secondary treatment techniques like activated sludge process, trickling filters, rotating biological contractors, composting, bioremediation etc.
Wastewater Treatment Process by Physico Chemical Methodsijtsrd
Contaminated water contains particles of different sizes which can be classified as dissolved 0.08 µm , colloidal 0.08 1 µm , supracolloidal 100 100 mm and settleable 100 µm . The type of treatment selected depends on the size of particles present in the wastewater. In practice, treatment efficiency also depends on particle size. Solids of the size that are visible to the naked eye can be separated either by settling under the influence of gravity or by flotation, depending on the relative densities of solids and water. They may also be easily separated by filtration. However, very fine particles of a colloidal nature called colloids, size 1 µm which have high stability are significant pollutants. The reason for this stability is that these particles have electrostatic surface charges of the same sign usually negative . This means that repulsive forces are created between them, preventing their aggregation and subsequent settling. It has therefore proved impossible to separate them by settling or flotation. It is not possible to separate these solids by filtration because they pass through any filter. However, separation by physico chemical treatments is possible. Physico chemical treatment of wastewater focuses primarily on the separation of colloidal particles. This is achieved through the addition of chemicals called coagulants and flocculants . These change the physical state of the colloids allowing them to remain in an indefinitely stable form and therefore form into particles or flocs with settling properties.

1. Protect anion resin from biofouling
12.10.2006 | Rahman, S., Karnaphuli Fertilizer Co. Ltd., Chittagong, Bangladesh
Good treatment practices can prevent this serious problem
Keywords:
Ion exchange resin in water (H2O) treatment plants can experience resin fouling due to different contaminants
present in source H2O. Microbial nutrients that are available in resin beds, under favorable temperatures and idle
conditions, may allow microorganisms to grow. This can be eliminated with appropriate treatment and/or
prevention.
Biological fouling is less severe in cation resin than in anion. However, both resin types present the same
operational difficulties with regard to biofouling. As the bed's pressure drop increases, drastic flow reduction
occurs, making backwash operations difficult due to out-flowing debris. Bacteria proliferation to other ion
exchangers can also happen. During shutdown or standby operation modes, resin is kept in a regenerated
condition. Resin preservation procedures for long-term storage are available.1
Biologically fouled cation resin
debris may be washed with filtered H2O. Conversely, it is more difficult to clean debris from anion resin and, after
cleaning, bacterial activity may still be present in anion resins.
Control microbial growth in your cooling water
05.01.2004 | Rahman, S., Karnaphuli Fertilizer Co. Ltd., Chittagong, Bangladesh
Proper monitoring and chemical dosing can alleviate this challenge
Keywords:
The hydrocarbon processing industry (HPI) needs cooling water (CW) to operate efficiently and safely. Cooling
water may be in either a circulating or open tower. Circulating CW needs regular chemical dosing and monitoring
to maintain desired water conditions. System performance is dependent on several factors: the right chemical
type, sufficient dosing, makeup water quality, plant location and the beneficiary plant characteristics.
The CW system is subjected to severe stress due to plentiful nutrients for microbial growth and subsistence. This
is due to the facility being located in a tropical monsoon area. Apart from any other cooling tower, it is supplied
with very good water quality tapped from deep wells, thus ensuring stable inorganic water character and
eliminating water quality variance.
Prevent adsorber bed failure
09.01.2002 | Rahman, S., Karnaphuli Fertilizer Co. Ltd., Chittagong, Bangladesh
Improved operational integrity minimizes plant upsets and challenges
Keywords:
Many applications require water (H2O) and/or other chemical species to be at low to non-detectable (ND) levels in
a process gas stream. Moisture separation from several thousand parts per million (ppmV) to the quality desired
can be achieved by compressing, cooling and forcing the gas through a separation medium causing moisture or
other chemical components to separate from the gas flow. Each application is treated in a way that is suited to
the system's technical needs. Two commonly used mediums are molecular sieves (molsieves) and silica gel
(gel). Molsieves can be used to remove sulfur compounds, carbon dioxide (CO2), ammonia and H2O molecules.
Gel may be used to selectively adsorb H2O molecules, oxygen (O2), n-butane and other species.
