“…This is demonstrated by the 1.5% TiO2:1.5% SBE membrane, which records a lower water contact angle value compared to the other membranes, indicating that it possesses the most hydrophilic properties. Furthermore, the structure of the membrane has an impact on its capacity to allow water to pass through [35,54].…”

Nowadays, polymer as the raw material has been utilized in the development of Hollow Fibre (HF) membranes. PVDF is a commonly used for HF membrane material. However, it has hydrophobicity properties and lead membrane becomes low permeability and fouling. Therefore, to avoid these membranes problems, the incorporation of inorganic nanoparticles into PVDF membranes matrix is necessary to be applied for significantly improving PVDF membranes performance. This study investigates the characteristics and performance of PVDF-TiO2 HF membranes using spent bleaching earth (SBE) as a promising material from industrial waste as a renewable inorganic nanoparticle. This novel PVDF-TiO2-SBE HF membrane was fabricated using the subsequent steps: The preparation process incorporates SBE revival through solvent extraction and thermal treatment alongside the wet spinning technique for membrane fabrication. The Fourier transform infrared (FTIR) functional groups, scanning electron microscope (SEM) morphology, water contact angle and pure water flux performance were investigated to specifically understand the performance of this typical HF membranes. The IR results show that Si-O-Si groups were found in the membrane matrices due to the addition of SBE material. The addition of TiO2-SBE particles also indicate a sandwich (sponge-finger-like) morphological structure on the cross-sectional, a rough and porous surface structures. The hydrophilic properties of the HF membrane and pure water flux performance are determined by the composition of the TiO2-SBE mixture added as an additive material. The minimum contact angle found at 74.33°, while the water flux is 5.81 kg.m-2.h-1 on the identical HF membrane. Accordingly, this approach significantly enhances the properties of the pure PVDF HF membrane.

The application of hollow fiber membranes is one of the excellent processes to treat oily wastewater and wetland water. Treating oily wastewater and wetland water is a significant challenge and reported expensive. These wastes generally come from due the expansion of massive industries and human activities these days. This review discusses the critical ways of membrane hollow fiber application in treating oily wastewater as well as wetland water. It is also reported in literature that there is mostly organic contaminant accommodated in oily wastewater and wetland water. Due to that, the application of hollow fiber is the best way as a removal organic contaminant in oily wastewater as well as wetland water. Apart from that, the conventional and advanced methods are also well explained within this review followed by detail treatments, application, and performance of this hollow fiber membrane application. To achieve the best completed outcome of pollutants removal, several applications relate to other processes before contacting to hollow fiber membranes. The integration between conventional and advanced membrane technology in oily wastewater and wetland treatment is also well explained. The important factors in the fabrication and application of hollow fiber membrane depend on membrane materials and filtration processes. It means that the selection between membrane materials and final processes to choose are depending on the urgency, source of pollutants, and intended use.
