High Efficiency Biofilm Carrier MBBR Filter Media 11mm X 7mm Size And White Color
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
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
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
