The AnoxKaldnes™ MBBR (Moving Bed Biofilm Reactor) process is a biological wastewater treatment process that utilizes specialized plastic carriers to create a surface on which a biofilm can attach. The carriers are mixed in the reactor, and their large surface provides capacity for a large biomass inventory, reducing the volume required for treatment. In the AnoxKaldnes MBBR process, most of the biomass resides in the biofilm on the carriers.

The AnoxKaldnes™ Hybas™ technology is an application of the IFAS process – Integrated Fixed-Film Activated Sludge. The same AnoxKaldnes MBBR media are used in the Hybas process, the difference being the carriers are used in an activated sludge environment. The suspended-growth biomass of the activated sludge and the biofilm on the carriers work together to provide higher treatment capacity in a smaller volume than that required for activated sludge alone.
