An introduction to MBBR (moving bed biofilm reactor )/ FM Reactor/ FAB /FMR Reactor wastewater treatment

When communities of microorganisms grow on surfaces, they are called biofilms. Microorganisms in a biofilm wastewater treatment process are more resilient to process disturbances compared to other types of biological treatment processes.  Thus, biofilm wastewater treatment technologies can be considerably more robust especially when compared to conventional technologies like activated suldge process..
In the MBBR biofilm technology the biofilm grows protected within engineered plastic carriers, which are carefully designed with high internal surface area. These biofilm carriers are suspended and thoroughly mixed throughout the water phase. With this technology it is possible to handle extremely high loading conditions without any problems of clogging, and treat industrial and municipal wastewater on a relatively small footprint.

System description

The MBBR™ biofilm technology is based on specially designed plastic biofilm carriers or biocarriers that are suspended and in continuous movement within a tank or reactor of specified volume. The design of associated aerators, grids, sieves, spray nozzles and other integral parts to the reactor is also of great importance in making up the system as a whole .
The industrial and municipal wastewater is led to the MBBR™ treatment reactor where biofilm, growing within the internal structures of the biocarriers, degrade the pollutants.  These pollutants that need to be removed in order to treat the wastewater are food or substrate for growth of the biofilm.  The biocarrier design is critical due to requirements for good mass transfer of substrate and oxygen to the microorganisms  .  Excess biofilm sloughs off the biocarrier in a natural way .

An aeration grid located at the bottom of the reactor supplies oxygen to the biofilm along with the mixing energy required to keep the biocarriers suspended and completely mix within the reactor.

Treated water flows from reactor through a grid or a sieve, which retains the MBBR™ biocarriers in the reactor. Depending on the wastewater, the reactors are may be equipped with special spray nozzles that prevent excessive foam formation.

The MBBR is a biological aerobic degradation of organic pollutants. The process utilizes millions of tiny, polyethylene biofilm elements that provide a high surface area as a home for a vast, highly active bacteria culture. This fixed film process features a flexible reactor design, the ability to handle load increases without the need for extra tankage, and remains stable under large load variations, including temperature, strength or pH. Like the activated sludge process, the MBBR process utilizes the whole volume of an open tank. Unlike an activated sludge reactor, it does not require sludge return to operate effectively. In MBBR , addition of media quantity and Air Quantity is the Key Factor.

Total reactor volume of the MBBRs is designed for different hydraulic retention time for different types of waste water at average flows and than checked against peak flows. Essentially nutrient levels and DO levels are the only control points for the system.



Moving Bed Biofilm Bioreactor (MBBR) process uses the whole tank volume for biomass growth. It uses simple floating media, which are carriers for attached growth of biofilms. Biofilm carrier movement is caused by the agitation of air bubbles. This compact treatment system is effective in removal of BOD as well as nitrogen and phosphorus while facilitating effective solids separation.

Design and Construction Principles

Neutralised and settled wastewater passes through MBBR for reduction in BOD/COD. Most of the MBBR plants are provided with vertically or horizontally mounted rectangular mesh sieves or cylindrical bar sieves. Biofilm carriers are made up of high density (0.95 g/cm3) polyethelene. These are normally shaped as small cylinders with a cross inside and fins outside. The standard filling of carrier is  not more than 465 m2/m3. Generally, design load for COD-BOD removal is 20 g COD / m2d. Smaller carriers need smaller reactor volume at a given loading rate (as g/m2d) when the carrier filling is same. 

It is advisable to use MBBR in combination with a DEWATS  as a pre-treatment unit, depending on the local conditions and input characteristics. It is a very robust and compact alternative for secondary treatment of municipal wastewater, having removal efficiency for BOD 90 – 95% (low rate) and that of 75 – 80% for high rate. Average nitrogen removal is about 85%. There is no need for sludge recirculation. Phosphorus and faecal coliform reduction is feasible with additional passive (non-mechanical) or active (mechanical) system components.


A constantly operating MBBR does not require backwashing or return sludge flows. It has minimal head-loss. Coarse-bubble aeration in the aeration zone in the wastewater treatment tank provides ease of operation at low-cost. Agitation continuously moves the carrier elements over the surface of the screen thus preventing clogging. Maintenance of MBBR system includes screening, influent equalisation, clarifier system, sludge handling and integrated control system. There is no need to maintain f/M ratio as there is self-maintenance of an optimum level of productive biofilm. Skilled labour is required for routine monitoring and operations of pumps and blowers.

Shaykh (Peer in Urdu & Persian) khalifa mureed in Islam


http://raza-e-khushtar.org/articles/practicing-islam/significance-of-taking-bayah

Source of the article:; http://www.spiritualfoundation.net/shaykhmureed.htm

The origin of this "bay'ah" is traced all the way to the Noble Prophet, salla Allahu 'alayhi wa sallam, when he took the bay'ah from his Noble Companions under the tree (Bay'at al-Ridwan), thus, Allah, Ta'ala became pleased with them and He stated:

Translation: "Indeed, ALLAH ('azza wa Jalla) was well-pleased with the Believers when they gave the bay'ah (pledge) to you (O Muhammad, salla Allahu 'alayhi wa sallam) under the Tree.."
[Surah 48: al-Fath, Verse:18]

He, Subhanahu wa Ta'ala, further states:

Translation: "Verily, those who give bay'ah (pledge) to you, (O Muhammad, salla Allahu 'alayhi wa sallam) they are giving bay'ah (pledge) to ALLAH ('azza wa Jalla). The Hand of ALLAH is over their hands. [Surah 48: al-Fath, Verse: 10]

It has been narrated that Sayyiduna 'Uthman, the Third Khalifa, was not present at the time of this bay'ah, so the Messenger of Allah, salla Allahu 'alayhi wa sallam, placed his own hand on his other hand and stated: "This is Allah's Hand of Power and this is the hand of 'Uthman". Thus, the Prophet, salla Allahu 'alayhi wa sallam, placed one hand on top of the other and took the bay'ah (from 'Uthman).

When the Noble Prophet, salla Allahu 'alayhi wa sallam, finished taking the bay'ahfrom the Noble Companions, he went in his house and the female Companions (Allah, be well pleased with them all), were present awaiting and ready to take the bay'ah. The Noble Prophet, salla Allahu 'alayhi wa sallam, paused for a while (thinking of whether he should take the bay'ah from them or not) so the verse was revealed:

Translation: "O Prophet (salla Allahu 'alayhi wa sallam)! When believing women come to you to give you bay'ah (pledge), that they will not associate anything with ALLAH, and nor will they steal, and nor will they commit adultery, and nor will they kill their children, and nor will they utter slander, intentionally forging falsehood and that they will not disobey you in any m'aruf (Good), then (O Messenger!) accept their bay'ah (pledge) and ask ALLAH to forgive them. Verily, ALLAH is Oft- Forgiving, Ever Merciful."
[Surah 60 – al-Mumtahinah – Verse: 12]

The Noble Prophet, salla Allahu 'alayhi wa sallam, also took bay'ah from the believing women. HOWEVER, THE PROPHET'S, salla Allahu 'alayhi wa sallam, HAND NEVER TOUCHED THAT OF A WOMEN'S, THIS IS WHY SAYYIDAH 'A'ISHA AL-SIDDIQA, Radi Allahu 'anha, stated:

"The Prophet (salla Allahu 'alayhi wa sallam) took the bay'ah from the (believing) women verbally, his blessed hand never touched a woman's hand"

Sayyidah 'A'isha, Allah be well pleased with her, stated that the "Noble Prophet's,salla Allahu 'alayhi wa sallam's, hand never touched the hand of a woman", whether she was young or old.
