MBBR (moving bed bioreactors) use additional media within the wastewater plants to increase the biofilm and speed COD removal rates. A facility that processes canola oil outgrew their wastewater process and was violating effluent COD discharge permits. In addition, during slow times he MBBR’s had a tendency for Nocardia foam.
Treatability testing by Aquafix Laboratories determined the addition of our Qwik-Zyme L and Qwik-Zyme P into the front end of their process could speed the breakdown of COD. They have noticed a 20-30% improvement in effluent COD.
