AnoxKaldnes™ Moving Bed Biofilm Reactor (MBBR) and Hybas™ (Hybrid Biofilm Activated Sludge) Processes
AnoxKaldnes Hybas™
The MBBR and Hybas™ processes are based on attached growth biofilm principles of biological wastewater treatment. The core of the processes is the biofilm carrier elements or media. While the biofilm is fixed to the media, the media is thoroughly mixed within a reactor and retained in the reactor.
In a MBBR application, all the biomass is attached on the media and retained in the biological reactor, so there is no return sludge. In a Hybas™ application, the reactor contains both free-floating biomass (activated sludge) and biomass attached to the AnoxKaldnes™ media. The free-floating biomass passes through the reactor, is settled and recycled back to the reactor. The media and attached biofilm remain in the reactor as in a MBBR.
Biofilm media
Kruger offers a range of biofilm media types to meet the varying demands of wastewater treatment applications. Options include the high specific-surface-area Biofilm ChipTM carriers. The high surface area of these carriers makes the most of available treatment volumes by concentrating the active biomass. For example, nitrification can be achieved in existing tanks where other media types could not provide enough surface area and, consequently, enough biomass.
