A new type of reverse osmosis (RO) membrane incorporating S‐Beta zeolite nanoparticles was synthesized through interfacial polymerization of m ‐phenylenediamine and trimesoyl chloride on the surface of nanoporous membrane support. The presence of S‐Beta zeolite in the polyamide layer of RO membrane was detected by scanning electron microscope equipped with energy dispersive X‐ray spectroscope. The impacts of S‐Beta zeolite loading ranging from 0.01 to 0.1 wt% on the separation performance of membrane were further studied and the results showed that the optimal S‐Beta zeolite for RO membrane was at 0.05 wt%. Compared to the control RO membrane without nanoparticles that showed water flux of 25.36 L/(m 2 .h) and NaCl rejection of 97%, the membrane incorporated with optimal zeolite loading exhibited better performance (65.25 L/(m 2 .h) and 97.33%) when tested using 1500 ppm NaCl solution at 300 psi.
