[Investigation of the methods of extension of useful life of nanofiltration membranes in washing water regenerating system].
Transport and selective characteristics of Russian nanofiltration membranes OPMN-K were investigated in order to find approaches to extend useful life of the membranes and, therefore, of the nanofiltration assembly and the washing water regenerating system at large. Hygienic cleansing agents as washing water ingredients pollute but not irreversibly impair the membranes. Flushing of membranes after regeneration of various model detergents was shown to recover the membrane permeability virtually up to original level.
