Micropollutant removal capacity and stability of aquaporin incorporated biomimetic thin-film composite membranes.

ABSTRACT: Aquaporin incorporated nanofiltration membranes have high potential for future applications on separation processes. In this study, performance of biomimetic thin-film composite membranes containing Halomonas elongata and Escherichia coli aquaporins with different affinity tags for the removal of micropollutants was investigated.% rejection of the membranes for atrazine, terbutryn, triclosan, and diuron varied between 66.7% and 90.3% depending on the type of aquaporin and micropollutant. The highest removal rate was achieved with a membrane containing H. elongata aquaporin for atrazine and terbutryn which have methyl branching in their structure. Electrostatic interactions between micropollutants, thin-film layer of the membrane, and tags of aquaporins may also play im
