摘要: Recently, enzymatic quorum quenching (in the form of a free enzyme or an immobilized on bead) was successfully applied to submerged membrane bioreactor with microfiltration for wastewater treatment as novel approach control biofouling. In this study, (acylase) directly onto nanofiltration mitigate biofouling in process. flow cell experiment, acylase-immobilized activity prohibited formation mushroom-shaped mature biofilm due reduced secretion extracellular polymeric substances (EPS). The maintained more than 90% its initial 20 iterative cycles reaction and washing procedure. lab-scale continuous crossflow system operated at constant pressure 2 bar, flux (NF) i...
