Project - The Impact of Flow Alteration Aids on The Thermal Performance of Vacuum Membrane Desalination Modules

Desalination and water treatment systems play a vital role in addressing the pressing issue of water scarcity. Among the available existing desalination methods, vacuum membrane desalination (VMD) systems stand out as environmentally friendly options with significant advantages. These include the highest production rate among membrane desalination systems, reduced mechanical property requirements for membranes, and the production of high-purity product water.

However, it's important to acknowledge that VMD systems face their own set of challenges. These encompass a low gained-output ratio (GOR), high energy consumption, and relatively high-water production costs. To address these issues, this research aims to conduct a thorough and precise analysis of the performance of two types of VMD systems: flat sheet and hollow fibre VMD. The methodology involves several steps. Firstly, the simpler versions of these systems will be modelled, simulated, and experimented. The energy thermal distribution, thermal performance, pressure and velocity distribution, production, and water production costs of these systems will be compared. Next, considering temperature polarization as a critical issue in VMD systems, a modified flat sheet VMD system will be designed, modelled, simulated, and tested. The resulting thermal distribution, thermal performance, pressure and velocity distribution, and production will be compared with the unmodified version of flat sheet VMD. Similarly, a modified hollow fibre VMD system will be designed, modelled, simulated, and tested, with a subsequent comparison of its thermal distribution, thermal performance, pressure and velocity distribution, and production standard version of hollow fibre VMD. Finally, an exergy and economic analysis of all systems will be conducted, culminating in the determination of exergy destruction and the water production cost for each of them.
