Abstract

Membrane distillation is a thermal and pressure-driven process through hydrophobic microporous membranes, it is a promising technology for water desalination. In this article, a modeling and simulation approach of Multi-Effect Vacuum Membrane Distillation (MEVMD), was implemented and verified using the experimental results of small scale locally designed and manufactured system, using an early prepared hydrophobic microporous membrane. The energy economization of the system is enhanced through latent heat recycling. Theoretical analysis of this system was achieved through the development of a lumped parameter model to describe the MEVMD performance. The developed model was solved numerically for different design and operating conditions using MATLAB Simulink software. The model was verified and validated using the experimental results to achieve a reliable tool for design, replication, scaling-up, and optimization.
