Membrane distillation using solar energy – membrane modification

  • 1 Lodz University of Technology, Faculty of Process and Environmental Engineering, Lodz, Poland


The desalination is an important technological process applied not only to obtain drinking water, but also for wastewater treatment from e.g. dyes, textile and mining industry. In this process, membrane processes such as reverse osmosis, pervaporation, electrodialysis and membrane distillation are quite commonly used. This work focuses on membrane distillation. The research was carried out in order to produce membranes absorbing solar radiation, to use this energy in the distillation process. Membranes were produced using the phase inversion method from polysulfone polymer at various proportions of ingredients to select the optimal blend composition. The fabricated membranes were investigated to assess wettability, maximum pore size and execute preliminary tests of the membrane distillation process.
