Moving Bed Biofilm Reactor (MBBR) — Dakshari Enterprise
The Moving Bed Biofilm Reactor (MBBR) is a modern wastewater treatment solution that combines the strengths of activated sludge and traditional biofilm systems while eliminating their limitations. This technology is designed to operate continuously without clogging, requiring no backwashing, offering low head loss, and providing a high biofilm surface area for effective treatment.
MBBR achieves this by using small carrier elements made of polyethylene or polypropylene, shaped as tiny cylinders ranging from 9 to 64 mm in diameter depending on the application. These carriers float and move freely within the reactor, driven by the aeration system. The carrier filling rate typically ranges from 10% to 65%, depending on the treatment requirements.
How It Works
Microorganisms attach themselves to the carriers, forming a protective biofilm. This biofilm ensures that the microorganisms are highly resilient, allowing the system to tolerate variations in wastewater quality, sudden load changes, and even extreme conditions. The efficiency of the biofilm makes the MBBR system compact, easy to maintain, and self-regulating, as the amount of active biomass adapts according to the incoming load and hydraulic retention time.
Since the carriers are continuously in motion, the MBBR process is largely insensitive to suspended solids in the incoming wastewater, ensuring consistent performance.
