Abstract: A method is disclosed for separating impurity components, UV absorbers and/or UV absorber precursors contained in an ethylene glycol-water stream thereby desirably allowing the recovery of the glycols contained in such stream in an economical and efficient manner. Specifically, these undesirable components are separated by contacting the ethylene glycol-water stream with a suitable semi-permeable membrane to effect such separation.
