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
schematic of the principle in an implementation of the WOCK OLIVER
MBBR technology is shown below
(Figure 1).

Small Boss MBBR Biofilm Carries
We supply a range of biofilter media, This product is sold by the
cubic metre. These products are suited to fluidized or moving bed
tank systems. These are also called "Biofilm Reactor (MBBR)"systems
and are used for treatment of water and wastewater.
Self cleaning due to turbulence:
Due to the turbulent movement of the biofilter media in
suspension,the filter media is self-cleaning ,requiring no
maintenance.This allows the filter to reach optimum effeciveness
without the disturbance of periodic maintenance,avoiding
unnecessary loss of bacteria within the filter.This allows
stable,low levels of ammonia and nitrite within the water.
The first few of these products are similar to the patented kaldnes
media used in fish farming and waste treatment .The design creates
an environment for effective nitrification to take place .Twater
flow is created by aeration tha circulates the media throughout the
vessel .This high suface area of these products traslates into a
small physical area needed for the biofiltration unit.
Due to vigorous mixing of the kaldnes-like media through
aeration,the media is self-cleaning,Requiring no maintenance.This
allows the filter to reach optimum effectiveness
Periodic maintenance is not necessary,preventing the unnecessary
loss of bacteria and subsequent ammonia and nitrite spikes in the
system.
Media volume needed:
with good turbulence and aeration, a feed rate of between 0.25 kgs
and 0.75 kgs of 40% protein food per day requires 50 litres of
media.

The core of the MBBR technology are the biofilm carriers. They are designed to provide a large protected surface area for the biofilm and optimal conditions for the bacteria culturea when the carriers are suspended in water.
Small Boss has developed several types of carriers with different
shape, size and surface area. This gives us the flexibility to use
the best suitable carrier depending on wastewater characteristics,
pretreatment, discharge standards and available volumes. Currently
we have ten different types of carriers
