Improving membrane fouling via high phyllosilicate properties of ZnO-Kaolin in pilot-scale hybrid membrane photocatalytic reactor (MPR) for superior river water treatment
A study evaluated a pilot-scale hybrid membrane photocatalytic reactor (MPR) using ZnO-Kaolin to treat polluted river water. ZnO-Kaolin was successfully synthesised and characterised using various methods, such as X-ray diffraction (XRD), fourier-transform infrared (FTIR), and field emission scanning electron microscopy (FESEM). XRD and FTIR analyses verified the purity of ZnO-Kaolin, showing no impurities, while FESEM revealed ZnO nanoparticle growth on kaolin surfaces. Additionally, the ZnO-Kaolin band gap was shifted, demonstrating enhancement of photo-degradation efficiency. Optimisation identified pH 5 as the most effective condition for treating the polluted Sembrong River via pilot-scale hybrid MPR integrated with ZnO-Kaolin, achieving significant removal of ammoniacal nitrogen (85.71 %), chemical oxygen demand (91.53 %), biochemical oxygen demand (84.93 %), and suspended solids (99 %). This innovative system also regulated water quality parameters, enhancing pH to 6 and dissolved oxygen to 6.3 mg/L while minimising membrane fouling. This innovative approach has promising potential for commercial-scale water pollution control.
期刊介绍：
Separation and Purification Technology is a premier journal committed to sharing innovative methods for separation and purification in chemical and environmental engineering, encompassing both homogeneous solutions and heterogeneous mixtures. Our scope includes the separation and/or purification of liquids, vapors, and gases, as well as carbon capture and separation techniques. However, it's important to note that methods solely intended for analytical purposes are not within the scope of the journal. Additionally, disciplines such as soil science, polymer science, and metallurgy fall outside the purview of Separation and Purification Technology. Join us in advancing the field of separation and purification methods for sustainable solutions in chemical and environmental engineering.
