Givaudan Flavors Corporation conducted a pilot study of the Kaldnes Moving Bed® Biofilm Reactor (MBBR) process at its East Hanover, NJ production facility for investigating its potential for pretreatment of its wastewater. For over 16 years the Kaldnes MBBR has demonstrated its performance and stability for both municipal and industrial wastewater treatment. For instance it [the Kaldnes MBBR] may be used as the first carbonaceous removal step in a two-step process with activated sludge for upgrading purposes (H. ødegaard, B. Rusten, J. Siljudalen).

The pilot study consisted of a two (2)-stage MBBR process train operated under aerobic conditions for carbonaceous BOD removal and contained Kaldnes K1 type biomedia. The MBBR demonstrated the ability to perform as a high-rate roughing reactor to the facility's existing activated sludge process. The full-scale MBBR installation is scheduled for completion in early 2005. The downstream existing AS process will polish MBBR effluent prior to discharge.
