MITIGATION OF TEMPERATURE POLARIZATION AND MINERAL SCALING IN MEMBRANE DISTILLATION: THE IMPACT OF INDUCTION HEATED ELEMENTS
… is still limited by technical challenges such as temperature polarization (TP), heat losses, scaling, and high energy consumption, as the feed solution requires continuous heating to provide an efficient driving force. The present work aims to develop and optimize a novel, efficient, and robust MD …

CFD simulation of polarization phenomena in direct contact membrane distillation systems
… on opposite sides of a hydrophobic membrane. The temperature difference causes water to evaporate from the feed, travel through the membrane, and condense in the distillate. Because DCMD is insensitive to osmotic pressure, it has emerged as a promising means of concentrating brines to their …

Instigating buoyancy driven convection to improve membrane distillation performance
… concentrations of dissolved solids. However, temperature polarization and concentration polarization reduce its distillate production and impede its industrial adoption. Surprisingly, no prior work has considered that temperature and concentration polarization both increase the feed density …

Enhanced membrane distillation : analytical and deionization applications
… heat loss through the membrane material, temperature polarization at the bulk feed-membrane interface, pore wetting and effective use of available membrane surface area. In this investigation, traditional membrane distillation was compared to membrane distillation using the same starting …
