SEPARATING MEMBRANE MODULE FOR TREATING WASTEWATER CONTAINING OIL, AND METHOD AND DEVICE FOR TREATING WASTEWATER CONTAINING OIL

摘要

PROBLEM TO BE SOLVED: To provide a separating membrane module suitable for filtration of wastewater containing oil.;SOLUTION: The separating membrane module for treating wastewater containing oil which separates water-insoluble oil contents from highly turbid and/or high-temperature wastewater containing oil is composed of an alkali resistant porous membrane selected from among PTFE (polytetrafluoroethylene), PSF (polysulfone) and PES (polyethersulfone), and uses a hollow fiber membrane of a tensile strength of 30 N or larger. A heat distortion temperature of the hollow fiber membrane and an end sealing material for the hollow fiber membrane is 100°C or higher.;COPYRIGHT: (C)2010,JPO&INPIT
