Improvement of biofilm activities in sequencing batch reactor via polyvinyl alcohol (PVA) granules addition

In this study, we conducted experiments to produce PVA granules that (i) have good biomass adhesion, withstand hydraulic shear force due to aeration, and settle quickly; (ii) perform wastewater treatment in column SBR configuration as a moving-bed biomass carrier, and (iii) prove the potential to a commercial production scale.
