Abstract
Recently, fabrication of membranes with low energy consumption has gained much attention of research. The aim of the current work was to design a new low-pressure and efficient multi-poly (piperazine-amide) thin layer which each layer formed alternatively upon a polyester nonwoven backing without using a polymeric support (unlike usual thin film membranes which use an ultrafiltration support). A desired rejection toward CuSO4 and Congo red day was obtained about 80 and 97%, respectively. Estimated pore size of the membranes (using molecular weight cut off test) showed the values from 150 to 325 Da. © 2017 The Korean Society of Industrial and Engineering Chemistry
