Moving Bed Biofilm Reactor (MBBR) Technology for Sewage treatment Plant


The Moving Bed Bio-film Reactor or MBBR process is based on the aerobic bio-film principle and it operates on utilizing the advantages of activated sludge and other bio-film systems without being restrained by their shortcomings. This technology is part of sewage treatment plant (STP).The main theme of this technology is the bio-film carrier elements that are made from polythene or plastic. This element provides a large protected surface area for the bio-film and optimal conditions for the bacteria culture to develop and flourish.


The MBBR system consists of an aeration tank (similar to an activated sludge tank) with special plastic carriers that provide a surface where a bio-film can grow. The carriers are made of a material with a density close to the density of water. The carriers will be mixed in the tank by the aeration system and thus will have good contact between the surface layer in the in fluent wastewater and the biomass on the carriers. It is necessary to have a strainer on the outlet of the tank so that the plastic carriers can be prevented from escaping the aeration. MBBR systems don't need a recycling of the sludge, which is the case with activated sludge systems. The MBBR system is often installed as a retrofit of existing activated sludge tanks to increase the capacity of the existing system. The degree of filling of carriers can be adapted to the specific situation and the desired capacity. Thus, an existing treatment plant can increase its capacity without increasing the footprint by constructing new tanks.

MBBR PROCESS SUMMARY

• Moving Bed Bio Reactor (MBBR) process is based on the bio-film of organisms developed on carrier elements.

• The media floats in the aeration tank and keeps floating by air from diffusers which are placed at the bottom of tank.

• The process is intended to enhance the activated sludge process by providing greater biomass in aeration tank and thus by reducing volume of the tank.

• After aeration tank, sedimentation tank is provided for settlement of sloughed biomass

• Clear water clarifier overflows from weir and is further subjected to disinfection.

Some advantages compared to activated sludge systems are:

·   Higher effective Sludge Retention Time (SRT) which is favourable for nitrification
·         Process performance independent of secondary clarifier (because of the fact that there is no sludge return line)
·         Responds to load fluctuations without operator intervention
·         Lower sludge production
·         Less space requirement
·         Resilient to toxic shock

India's speed of industrialization and development is at peak. New companies are becoming established every day. Of course in these companies, the best things are made for people but along with these, the waste material is expelled and the contaminated water also flows And the human wants that this waste material also be reused.  For these things there are many treatment plants available in India which purify contaminated water from fractures. Well, companies also have to be aware of the environment and It is also important to take the proper steps for the good of the people.  In India, Kelvin Water Technologies Pvt Ltd are one of the fastest and gradually waste water treatment company . Usually we use RO technology to clean water at home and It is usually used for saline water and kills all bacteria’s and viruses and gives us clean and disease free water. From Industrial area,  unwanted and poisonous substances are also expelled like haza...

Benefit of Wastewater Treatment Plant

Wastewater is the water used by residences/households and commercial/industrial entities that has become excessive polluted for further use. Such combination of different types of wastewater causes the resulting wastewater mix to contain suspended and dissolved organic as well as inorganic substances such as carbohydrates, fats, soaps, synthetic detergents, as well as various natural and synthetic organic chemicals. Why waste water treatment plant? The wastewater treatment plant does not only produce clean reusable water, but also has the potential to produce various other benefits. They treat the water that goes down our drains before discharging it back into the environment. The world has a growing and developing population and as things stand right now, we’re on a downward slope in terms of water conservation. The reuse of treated wastewater has become a viable option to minimizing water scarcity problems. Below are some explained benefits: Reduction of waste ...

Extended Aeration Activated Sludge Process Technology For Sewage Treatment Plant (STP)

Image
As the name suggests, it is a modified form of Activated Sludge Treatment system. Extended aeration is a method of sewage treatment using modified activated sludge procedures. Extended aeration agitates all incoming waste in the sludge from a single clarifies. Extended Aeration plants provide a low cost, odor and nuisance-free Sewage Treatment Plant that produces a high degree of treatment. Extended aeration treatment plants are used worldwide to provide simple and effective wastewater treatment . The combined sludge starts with a higher concentration of inert solids than typical secondary sludge and the longer mixing time required for digestion of primary solids in addition to dissolved organic produced sludge requiring greater mixing energy input per unit of waste oxidized. In  extended aeration  process, the raw sewage moves straight to the aeration tank for treatment. The whole process is aerobic. This simplification implies longer aeration time which ha...
