Abstract Water treatment technologies have evolved over the past few centuries to protect public health from pathogens and chemicals. As more than a billion people on this earth have no access to potable water that is free of pathogens, technologies that are cost effective and suitable for developing countries must be considered. Sustainable operation of these treatment processes taking into co...

This paper presents membrane distillation (MD), a separation process based on evaporation through pores of a hydrophobic membrane. Different configurations of the process were considered. Membrane properties, transport phenomena through the membranes, and module designs have been discussed. Applications of MD in water and wastewater treatment as well as in the food industry have been presented....

We systematically analyze power requirements of membrane and distillation processes for binary mixtures where the desired product component is more permeable also volatile. first derive a shortcut method to compare efficiency heat pump steam-driven distillations. Then, separation are discussed. Distillation generally requires lower when either high recoveries needed (at all tested purities), or...

Abstract In this study, an electrohydrodynamic atomization or electrospraying technique is used for the uniform deposition of carbon nanotubes (CNT) on a commercially available PTFE membrane and employed Membrane Distillation (MD) process. Modified PTFE-CNT was characterized water contact angle, liquid entry pressure (LEP), pore size distribution, surface morphology. The electrospray coating CN...
