Moving Bed Biofilm Reactor (MBBR)
Moving Bed Biofilm Reactor (MBBR) is an advanced wastewater treatment technology that utilizes suspended plastic media to foster the growth of beneficial microorganisms for the biological treatment of sewage. MBBR is known for its efficiency, compact design, and versatility in handling various types of wastewater.
Overview
Moving Bed Biofilm Reactor (MBBR)
The Moving Bed Biofilm Reactor is a biological treatment process that enhances the efficiency of wastewater treatment by providing a large surface area for the colonization of microorganisms. This is achieved through the use of small plastic carriers or media that move freely within the reactor, creating a dynamic and highly effective environment for the biological treatment of organic pollutants.
Key Components and Operation:
Bioreactor Tank:
The heart of the MBBR system is the bioreactor tank, where wastewater,
oxygen, and suspended plastic media interact to facilitate the biological
treatment process.
Plastic Media:
Small plastic carriers, often in the form of floating discs or cylinders, are used
to provide a surface for the growth of biofilm. These carriers move freely
within the reactor, ensuring constant contact with the wastewater.
Microbial Biofilm:
Microorganisms, including bacteria and other microbes, form a biofilm on the
surface of the plastic media. This biofilm serves as a substrate for the
treatment of organic pollutants present in the wastewater.
Aeration System:
Aeration diffusers or other oxygenation mechanisms are employed to provide
the necessary oxygen for the microbial community to thrive and efficiently
metabolize organic matter.
Effluent Clarification:
After the biological treatment process, the treated water typically passes
through a clarifier or settling tank to separate the suspended solids and
biomass.
