MBBR Moving-Bed-Biofilm-Reactor

The moving-bed biofilm reactor (MBBR) improves wastewater quality with floating plastic carriers — these serve as growth surfaces for microorganisms and biodegrade organic pollutants.

The Moving Bed Biofilm Reactor (MBBR) from IWAT is a highly flexible moving bed system that is equipped with free-floating plastic fillers.

These serve as carrier material on which microorganisms form a dense biofilm in a protected area. Through targeted interval ventilation and filling with waste water, the microorganisms continuously receive the required oxygen and nutrients, which effectively supports the biological purification process.

The pre-treated waste water is then fed into a storage tank. Here, it is homogenized by an agitator and fed into our CCF flotation for targeted separation.

The MBBR is characterized by its low tank volume, high load tolerance and uncomplicated operation, which make it particularly low-maintenance.

In addition, the system comprises advanced control technology including a ventilation system, oxygen measurement, a pH controller with caustic soda dosing pump and a Siemens S7-1513 substation with a 12-inch touch panel. This is integrated into the DAF unit's PLC. These components ensure precise monitoring and control of the cleaning process, optimize performance and support seamless integration into existing systems.

Biological treatment

The Moving Bed Biofilm Reactor - advantages at a glance:

raindrop icon
More microorganisms
Plastic carriers enable more efficient biodegradation of pollutants in water in the same space.
raindrop icon
Robust process
MBBR systems are highly tolerant of fluctuations in wastewater composition and load peaks.
raindrop icon
Low maintenance costs
Because of the design and self-regulation of bioactive carriers, MBBR systems require little maintenance and monitoring.
raindrop icon
Scalable & flexible
MBBR systems can be easily extended or modified to adapt to growing requirements.

Floating plastic carriers in the MBBR system

The floating plastic carriers in the MBBR (Moving Bed Biofilm Reactor) system are small, high-density polyethylene elements with a special porous structure that provides a large surface area for microorganisms to attach and grow, effectively biologically cleaning the wastewater.

The floating plastic carriers in an MBBR system are cleaned by the process itself, as the constant movement in the reactor means that biofilms do not thicken excessively or clog the carriers.
