Lessons Learned on Long-Term Operation of MBBR for Refinery Wastewater Treatment
Abstract:The Moving Bed Biofilm Reactor (MBBR) treatment process can be used as an add-on feature or can be an alternative to activated sludge for biological treatment of refinery wastewater, showing superior volumetric removal rates and eliminating the recirculation of sludge. In this paper, we examine the 11-year operation of the AnoxKaldnes™ MBBR for first-stage COD removal, its performance under various operating conditions, and its ability to withstand process upsets.
