Multi-Objective Optimisation of hybrid MSF-RO desalination system using Genetic Algorithm

Abstract

The aim of this research is to perform Multi-Objective Optimisation (MOO) 
study for multistage flashing with brine recirculation and hybrid MSF-RO 
desalination systems using Genetic Algorithm (GA) technique. The hybrid MSF-RO 
desalination system has been simulated rigorously using first and second laws of 
thermodynamics in addition to the plant economical aspects. Four objectives have 
been considered in this analysis: distillate production, product cost, Gain Ratio and 
exergy destruction. The desalination systems have been optimised for single, double 
and triple simultaneous objectives. Results showed that MOO of MSF-BR and hybrid 
MSF-RO systems were successful and tend to enhance the performance of both systems.
