Abstract
PURPOSE: To economically concentrate and recover the unreacted monomer in waste water by treating waste water containing the monomer of various polymerization processes by a reverse osmosis film.
CONSTITUTION: Unreacted monomer extracted waste water in a nylon-6 preparing process, evaporated and condensed water from an atmospheric pressure polymerization tower, polymer separated filtrate in an acrylonitrile copolymer preparing process, a polymer washing water or unreacted styrene containing waste water in an SBR emulsion polymerization process are treated in a reverse osmosis apparatus using a reverse osmosis film obtained from a high molecular compound such as cellulose ester or aromatic polyamide to highly concentrate the monomer in waste water and, according to necessity, high degree concentrating operation is further applied to recover the monomer. By this method, the monomer can be recovered in small energy compared to a conventional distillation method.
