ABSTRACT:
A method has been discovered for recovering polyoxyalkylene glycols from wastewater. A skimming surface is heated to a temperature above the cloud point. The heated surface is contacted with the wastewater, causing the polymer to deposit. Deposited polymer skimmed from the surface is recovered. Heating, or other processing of the bulk wastewater is avoided.
