COMPANY INSTRUCTION

Integrated Technology

BioCell® MBBR is a moving media system, be used in Integrated Fixed-Im Activated Sludge (IFAS) and moving bed biofilm reaction (MBBR) systems. Independently moving BioCell® carriers continually circulate through the aeration basin in a random motion, ensuring excellent oxygen and substrate transfer to the biomass. BioCell is a cost-effective solution for existing activated sludge plants that need more advanced treatment. Because little or no additional tankage is required, BioCell is an ideal solution for plants with limited room for expansion. It is also an excellent choice for space efficient, high performance new plant designs.

MBBR Aerobic Reactor

In aerobic aeration, the media

is fully agitated and mixed wit

h water; meanwhile the air is s

egmented into small bubbles,

which increases the contact ar

ea between biological membra

ne and oxygen, it also could in

creases the efficiency of oxyge

n transfer

MBBR Anaerobic Reactor

Under anaerobic conditions,

water flow and media be fully

agitated by agitator, in order

to let the biofilm and the

pollutants are fully exposed,

and achieve the purpose of

Integrated Technology

The main characteristic of Moving bed Biological Reactor(MBBR) configuration is that there is no sludge recycle from secondary clarifier, MBBR is essentially simple, once-through process, where all of the biological activity takes place on the biomass carriers. MBBR is usually followed by a solids separation system such as a secondary clarifier or DAF, in order to separate bio-solids produced in the process from the final effluent. The main advantage of MBBR is robust and simple reduction of soluble pollutants (soluble BOD or COD, NH4 +，etc.), with minimal process complexity, utilizing a significantly smaller footprint when compared to conventional aerobic treatment methods. MBBR is typically used for either high load industrial applications or for robust simple-to-operate municipal facilities.

MOVING BED BIO FILM REACTOR (MBBR)

Integrated Technology

The Integrated Fixed-film Activated Sludge (IFAS) process combines the advantages of conventional activated sludge with those of biofilm systems by combining the two technologies in a single reactor. Typically, an IFAS configuration will be similar to an activated sludge plant (utilizing all of the different process configurations such as MLE, UCT, Bardenpho, etc.), with biomass carriers introduced into carefully selected zones within the activated sludge process. This allows two distinct biological populations to act synergistically, with the MLSS degrading most of the organic load (BOD), and the biofilm creating a strongly nitrifying population for oxidation of the nitrogenous load (NH4+). IFAS is typically used to upgrade existing plants in order to enable extensive Nitrogen removal, or in designing new plants with significantly smaller footprints for extensive BOD and Nitrogen removal.
