Effect of alumina nanoparticles on the antifouling properties of polycarbonate‐polyurethane blend ultrafiltration membrane for water treatment

Abstract: In this work, the flexibility of polycarbonate (PC) membrane was improved by using polyurethane (PU) additive. However, due to the hydrophobic nature of the PU polymer, alumina (Al2O3) nanoparticles were incorporated to PC‐PU blend membrane. The prepared membranes have been used in a submerged membrane system to eliminate humic acid molecules from polluted water in both the presence and absence of coagulant (polyaluminum chloride). The obtained results showed that introduction of PU into PC membrane diminished… Show more

“…This study aimed at the preparation of PVC/clinoptilolite UF nanocomposite membranes for the removal of HA from contaminated water, in a submerged membrane system. According to the literature, besides membrane modification, operational conditions such as the transmembrane pressure (TMP) affect membrane fouling [28,29]. So, in this study, the effect of the TMP on the performance of the PVC/clinoptilolite nanocomposite membranes was also investigated.…”

“…In 2020, for example, China’s primary energy consumption reached 4.98 billion TCE, resulting in 9.9 billion tons of CO 2 emissions [ 1 ]. Researchers focus on finding solutions from environmentally friendly materials and natural materials that are commonly used in various fields such as energy storage [ 2 , 3 , 4 ] and photocatalysis [ 5 , 6 , 7 , 8 , 9 , 10 ] to alleviate environmental pressures. In recent years, there have been many remarkable results, such as: Zinatloo-Ajabshir et al for the first time using banana extract, prepared under mild conditions with good hydrogen storage performance (after 20 cycles, the discharge capacity of 2611 mA h/g) pure Pr 2 Ce 2 O 7 nanostructures [ 2 ].…”
