Moving Bed Biofilm Reactor (MBBR)
What is a Moving Bed Biofilm Reactor (MBBR)?
The Ecologix MBBR is a highly effective biological treatment process based on a combination of conventional activated sludge process and biofilm media. The MBBR process utilizes floating High Capacity MicroOrganism BioChips media within the aeration and anoxic tanks. The microorganisms consume organic material. The media provides increased surface area for the biological microorganisms to attach and grow. The increased surface area reduces the footprint of the tanks required to treat the wastewater. The treatment process can be aerobic and/or anaerobic and operates at high volume loads.
MBBR Media Used in Wastewater Treatment
Aeration tank: The tank is similar
to an activated sludge tank. The aeration is
used to keep in motion the activated sludge and
carriers. The MBBR system separates the excess
bacteria and sludge which are directed to the
final separator.
Special plastic carriers: They provide a surface for biofilm growth. Carrier materials are made of materials with a density close to that of water (1g/cm3) an example is high-density polyethylene (HDPE) with a density of 0.9g/cm3. These carriers are moved in the tank through the aeration system. This ensures good contact between the wastewater and the biomass on the carriers.
Benefits of MBBR Technology
- Saving of space due to its compactness
- Easy to maintain
- Good for a high volume of load
- Extension and expanding are easy. This made possible by increasing the filling degree of carriers.
- Lower discharge costs
- MBBR is not affected by toxic shock
- Independent process performance because there is no return line for sludge; the MBBR eliminates the return activated sludge (RAS)
- It has high effectiveness of sludge retention time (SRT) which enhances the nitrification process
- Production of sludge is lower
- It does not need recycling of the sludge-like activated sludge system
- MBBR media is installed to retrofit existing activated sludge tanks in order to increase its capacity
Design of MBBR Systems
It uses a combination of activated sludge process i.e. suspended growth and biofilter i.e. attached growth. It uses the entire tank volume for biomass growth by implementing the carriers for attached growth of biofilm. Movement of carriers is enabled by air bubbles through agitation.
The reactor can be in any shape and support different load depending on carrier filling. MBBR design of reactor depended on the actual wastewater characteristics and locality. The plants come either with vertical or horizontal mounted rectangular mesh sieves. The reactor can also be fitted with cylindrical bar sieves.
