The difference between sbr, mbr and mbbr-sewage treatment plantsCleantechwater_19
Cleantech is a leading name when it comes to sewage treatment plants in India. We provide advanced and reliable wastewater treatment plants, including MBR, MBBR & SBR plants.
Aerated lagoon shortly known as lagoon is widely used to the purpose of waste water treatment. It is a biological treatment process. No extra chemical is required for this process.
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.
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.
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.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

New Separation Processes
WASTEWATER TREATMENT
USING MEMBRANE BIOREACTORS
Presented on: 2nd November 2019
2. Conventional Wastewater Treatment Technique
2
• Conventional Activated Sludge Processes (CASPs) involve the natural biodegradation of
pollutants by heterotrophic bacteria (activated sludge) in aerated tanks.
• Activated sludge is separated by gravitational settling.
• Need for a large reactor size and further treatment of the sludge.
3. Membrane Bioreactor (MBR)
3
• Improvement of CASP – replacement of gravity settler with a membrane module.
• Can be operated at higher Mixed Liquor Suspended Solids (MLSS) concentrations compared to
conventional settlement separation systems, thus reducing the reactor volume to achieve the
same loading rate.
6. Membrane Separation – an overview
6
• Membrane – a barrier which separates two phases and
restricts transport of various molecules in a selective
manner.
• Driven by factors such as Pressure, Concentration,
Temperature, Electrical potential gradients.
• Permeate and Retentate streams.
• First generation processes – Microfiltration,
Ultrafiltration, Nanofiltration, Reverse Osmosis,
Electrodialysis
• Second generation processes – Gas separation,
Pervaporation
7. History of MBRs
7
• Late 1960s:
• The original process was introduced by Dorr-Oliver Inc.,
• Activated sludge bioreactor with a crossflow membrane filtration loop
• Problems: pumping and fouling.
• Application only in niche areas with special needs.
• 1989:
• Yamamoto and co-workers ideated about submerging the membranes in the bioreactor.
• Reduced energy consumption to a greater extent.
• Lower operating cost reflected in the decrease of membrane costs
Result: Exponential increase in the number of MBR plants since late 90s.
8. Further improvements
8
• While early MBRs were operated at solid retention times (SRT) as high as 100 days with MLSS up to 30
g/l, the recent trend is to apply lower solid retention times (around 10–20 days), resulting in more
manageable MLSS levels (10 to 15 g/l).
• Reduced operation and maintenance costs.
• There is now a range of MBR systems commercially available, most of which use submerged
membranes although some external modules are available; these external systems also use two-phase
flow for fouling control. Typical hydraulic retention times (HRT) range between 3 and 10 hours.
• Anaerobic membrane bioreactor (AnMBR):
Sludge is treated anaerobically by mesophilic bacteria which release methane as a byproduct.
The biogas can later be combusted to generate heat or electricity.
AnMBR is considered to be a sustainable alternative for sewage treatment because the energy that
can be generated by the methane combustion can exceed the energy required for maintaining the
process.
9. Pretreatment
9
• Purpose: To avoid unwanted solids in the waste stream, which enters the membrane tank.
• Fine screening is an essential pre-treatment step.
• This minimizes an accumulation of solids and protects the membrane from damaging debris and
particles, extends the membrane life, reduces operating costs and guarantees a higher sludge quality
as well as a trouble free operation.
10. Pretreatment – Fine Screening
10
• In Wastewater Screening, Fine screens have clear openings less than 6 mm.
• They consisted of perforated plates, wire cloth, wedge wire elements that have smaller openings.
They are also used to remove the fine solids present in the primary effluent.
• Fine screens are classified as:
• Static (fixed) wedge wire screen
• Rotary drum screen
• Step type screen
11. Process configurations
11
Internal/submerged :
Membranes are immersed in and integral to the biological
reactor.
The filtration element is installed in either the main
bioreactor vessel or in a separate tank.
The membranes can be flat sheet or tubular or
combination of both, and can incorporate an online
backwash system which reduces membrane surface
fouling by pumping membrane permeate back through
the membrane.
12. Process configurations
12
External / side stream :
Membranes are a separate unit process requiring an
intermediate pumping step. The filtration elements are installed
externally to the reactor, often in a plant room.
The biomass is either pumped directly through a number of
membrane modules in series and back to the bioreactor, or the
biomass is pumped to a bank of modules, from which a second
pump circulates the biomass through the modules in series.
Cleaning and soaking of the membranes can be undertaken in
place with use of an installed cleaning tank, pump and pipe
work.
13. Advantages and disadvantages
13
Advantages
High quality effluent
Lower sludge production
High loading rate capability
No further polishing required for
disinfections or clarifications
Higher nitrogen removal rate
Disadvantages
ˣ Membrane surface fouling
ˣ Membrane surface clogging
ˣ High capital cost
ˣ High running cost
ˣ Process complexity
