Abstract
An experimental study for industrial wastewater was carried out using a cross-flow microfiltration unit. The effect of various nanofibrous membrane structures on the membrane permeability was investigated. Analysis of variations in nanofiber area weight, supporting material, the hydrophilicity of membranes, and the polymeric structure of the nanofiber layer revealed considerable effects on membrane permeability, the total amount of filtrated permeate and the total amount of carbon in the permeate solution. The removal of total organic carbon (TOC) was gradually decreased with the increasing area weight of the nanofiber layer. Low area weight nanofiber composite membranes were superior over high area weight ones, as a higher membrane permeability was maintained during the 15 hour test. The results indicate that the selection of the area weight of the nanofiber layers as well as the supporting layer are a key factor for increasing the flux and permeability.
