Assessment of performance and efficiency of membrane distillation for treatment of impaired water and brine with high scaling potential
Water recovery is limited in pressure-driven membrane processes such as reverse osmosis (RO) and nanofiltration (NF) due to increase in scaling risk and osmotic pressure of the feed water with concentration. Membrane distillation (MD) is an emerging thermally-driven membrane desalination processes …
