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
