dc.description.abstractFirstly, the background knowledge of this work for better understanding of the types of membranes, membrane preparation techniques, functionalization, characterization, and applications are investigated. Membrane technology presents an attractive character comprising of easy manufacturing, modification, operation, and compactness. Several membrane preparation techniques are assessed and compared in detail. Moreover, the functionalization using physical blending and grafting methods for the modification of polymer and/or membrane are discussed. Finally, the possible applications of the membrane processes have been extensively discussed for water and wastewater treatments. Secondly, a detailed literature review about the preparation, modification and application of the polymeric membranes were discussed. A particular emphasises given to the phase inversion and electro-spinning techniques of membrane preparations. On the other hand, the functionalization and/or grafting effects on the resultant membrane structures were assessed regarding their specific applications. Moreover, the possible scopes for further enhancement on the preparation and modifications of the membranes are also identified. Furthermore, the specific objectives on the preparation, characterization, modification, and application of the polymeric membranes have been discussed extensively. Furthermore, valuable information on the chemicals used, methods of membrane preparation, and characterization techniques were provided. Detailed information on the preparation procedures, physicochemical and instrumental characterization techniques are also presented. An empirical investigation into the impacts of time duration, voltage supply, concentration, and flow rate on the membrane average fiber diameter and surface pore size distribution was done using response surface methodology (RSM) based on central compact design (CCD) are presented. Additionally, the effect of glutaraldehyde on membrane crosslinking was also assessed for further studies.en_US
