A Thin Film Nanocomposite Reverse Osmosis Membrane Incorporated with S‐Beta Zeolite Nanoparticles for Water Desalination

Abstract

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/(m2.h) and NaCl rejection of 97%, the membrane incorporated with optimal zeolite loading exhibited better performance (65.25 L/(m2.h) and 97.33%) when tested using 1500 ppm NaCl solution at 300 psi.

Synthesis and Characterization of Anti‐fouling Ultrafiltration Nanocomposite Membranes Integrated with S‐β Zeolite Nanoparticles for Oily Wastewater Treatment

“…In the ATR-FTIR spectra of the nanocomposite membrane, a noticeable change can be observed in the peak at around 1672.9 cm À 1 , which corresponds to the C=O (carbonyl) stretching vibration and 2971.7 which corresponds to the OÀ H stretching vibration. [19] This indicates a possible hydrogen interaction between the S-β zeolite nanoparticles and the functional OH groups of PSf polymer. This interaction may also occur at the active sites of the nanocomposite membrane, indicating the successful incorporation of S-β zeolite nanoparticles and their potential impact on the membrane's properties.…”

“…[17] The ion exchange properties of β zeolite selectively absorb foulant species like heavy metals, [18] combating membrane fouling. [17,19] Acting as a physical barrier, it sieves out larger molecules that cause fouling, and its stability ensures compatibility with various materials and conditions. This costeffective approach involves simple blending or coating during fabrication, minimizing complexity.…”
