The chlorination process did not harm membrane performance. In addition, the PEK-N-Cl membrane was stable in both air and water. The PEK-N-Cl membrane exhibited excellent antimicrobial properties against both Gram-negative and Gram-positive bacteria (i.e. E. coli and Bacillus subtilis, respectively). The PEK-N-Cl membrane provided 94.2% and 100% reduction of E. coli and Bacillus subtilis, respectively, within 30 min of contact times. Moreover, nearly 100% of the E. coli was killed after 2 h during the filtration process for the PEK-N-Cl membrane. In addition, the water flux decreased by 42% for the PEK-N-Cl membrane compared to 77.6% for the PEK-NH membrane after filtration of the E. coli solution and incubation on LB nutrient agar plate, indicating that the PEK-N-Cl membrane enhibits antifouling. Furthermore, the PEK-N-Cl membrane is recyclable via subsequent exposure to a sodium hypochlorite solution. \u00a9 2017 Elsevier Inc.<\/p>\n<p>&nbsp;<\/p>\n<p>DOI:&nbsp;10.1016\/j.jcis.2017.01.054<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Journal of Colloid and Interface Science Volume 496, 15 June 2017, Pages 391-400,&nbsp;ISSN: 00219797 Hou, S., Dong, X., Zhu, J., Zheng, J., Bi, W., Li, S., Zhang, S.
