Numerical Modelling and Performance Evaluation of Vacuum Membrane Distillation for Energy-Efficient Seawater Desalination: Towards Energy-Efficient Solutions

Résumé

Vacuum membrane distillation (VMD) is a compelling technique for desalinating water because it exhibits superior pure permeability at lower operating temperatures compared to other technologies. This leads reduced energy consumption, heat loss via conduction across the surface, and minimal transfer through due low pressure on permeate side. Detailed modelling of mass in VMD essential optimizing process as provides valuable insights that contribute advancement successful implementation seawater desalination using technology. The aim this study establish comprehensive numerical model describes vapor hydrophobic micro-porous single-stage multi-stage processes desalination. predictions were experimental data addition computations based an existing literature database, good agreement has been found. investigation also conducted sensitivity analysis variables specifications performance, well assessment impact temperature concentration polarization. obtained results showed permeation flux reached 18.42 kg/m2·h 35 g/L feed concentration, 65 °C temperature, 50 L/h flow rate, 3 kPa vacuum pressure. Moreover, findings revealed was most significant factor, while rate least important determining flux. Additionally, suggested effectiveness heavily relies composition support materials. Finally, confirmed polarization had more effect reduction than
