The Department of Chemical Engineering at the University of Technology discussed the master's thesis tagged.
Fabrication of PVC-PA thin film forward osmosis membrane for direct fertigation applications
The student Bakr Mohamed Ibrahim's thesis aimed to fabricate composite thin films and evaluate them in the FO process for direct composting applications. PVC films with porous top surface structure were prepared in different concentrations by phase inversion process. While the PA thin film was prepared on the top porous surface of PVC substrate using interfacial polymerization reaction with different concentrations and reaction times to improve the performance of FO. A comprehensive characterization of the membranes was also carried out. The results showed that the water flow of the composite thin films improved with the reduction of the amount of PVC. It also showed an improvement in water flow while reducing the concentration and reaction time of the PA layer. Also, the effect of several variables on membrane performance was studied, including membrane orientation, flow rate, draw solution concentration, and feed solution concentration. It has been demonstrated that using a membrane with a porous superstructure surface as a substrate is a reasonable strategy for preparing a high-performance FO membrane.
