Project Description and Objectives

Although Membrane Distillation (MD) has been extensively studied for desalination, it has other applications such as removing diverse of solutes from water and concentrating non-volatile substances. Emerging contaminants, such as various pharmaceutical or personal care products (PPCPs), could give rise to adverse ecological and human health impacts.  MD offers the possibility of producing a clean stream while concentrating emerging contaminants and pathogens present in wastewater in order to facilitate their chemical elimination. MD is a thermally driven separation process, driven by vapor pressure differences existing between the porous hydrophobic membrane surfaces. However, the current MD membrane still suffers from limitations such as low permeate flux rates and the wetting of the pores during the MD process. In this study, the super hydrophobic property of the membrane is obtained by adding surface-modifying macromolecules into the dope solution. The electrospinning technique is used to fabricate this kind of nanofiber membrane.
