MBBR Technology and Biofilm Carries
MBBR technology is based on the biofilm principle with an active
biofilm growing on small specially designed plastic carriers that
are kept suspended in the reactor. The technology utilizes the
advantages of both activated sludge and other biofilm systems (e.g.
biofilters, biorotors etc.) without being restrained by their
disadvantages.
The carriers are designed to provide a large protected surface area
for the biofilm and optimal conditions for the bacteria culture
when the carriers are suspended in water.
Solutions based on MBBR technology is mainly used in the following
applications:
+ For new plants, especially those requiring a small footprint and
easy operation, for BOD/COD and nitrogen removal
+ As a high loading system in front of existing biological
treatment - roughing reactor
+ To increase the amount of nitrifying bacteria in existing
activated sludge system using the WOCK OLIVER carrier in a hybrid
plant to meet ammonia limits
+ To implement post-treatment to existing plants for process
improvements
MBBR Technology
Technical Details
The aerated MBBR uses, as the activated sludge process, the whole
volume of an open tank. It is defined as a biofilm system, as the
biomass is growing on carriers that move freely within the reactor
volume and are kept within the reactors by a sieve at the reactor
outlet. The system can be used either for aerobic or anoxic
processes. In aerobic processes the biofilm carriers are kept in
suspension by the agitation created by air from aeration diffusers,
while in anoxic processes a mixer keep the carriers in movement. A
