K2 Plastic Filter 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
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
