In this work, the influence of adding ZSM-5 zeolite into the membrane bioreactor for fouling reduction of membrane and chemical oxygen demand (COD) removal was studied. We used a 60cm×22cm×5.6cm micro filtration PVDF membrane. Adding ZSM-5 zeolite to system reduced transmembrane pressure (TMP) by 25% and COD removal efficiency in system with ZSM-5 was about 11.82 % higher than system without zeolite. Furthermore, the soluble microbial product (SMP) concentration in the sludge decreased in the system with ZSM-5 zeolite.
