For treating pulp and paper (P&P) industry wastewaters, the high-loaded/nutrient-limited moving bed biofilm reactor (MBBR) is frequently followed by an activated sludge, in the Biofilm-Activated Sludge (BAS) configuration. Evidences show that the MBBR performance relies on a complex surface-volu...
