Document Type and Number:
WIPO Patent Application WO/2011/101961
Kind Code:
A1
Abstract:
Disclosed is a separation membrane module which is suitable for filtration of oil-containing waste water. Specifically disclosed is a separation membrane module for processing of oil-containing waste water, which separates a water-insoluble oil content from oil-containing waste water that is highly turbid and/or at a high temperature. The separation membrane module for processing of oil-containing waste water is characterized by using a hollow fiber membrane which is composed of an alkali-resistant porous membrane selected from among polytetrafluoroethylene (PTFE), polysulfone (PSF) and polyether sulfone (PES) and has a tensile strength of not less than 30 N. The separation membrane module for processing of oil-containing waste water is also characterized in that the heat distortion temperatures of the hollow fiber membrane and a terminal sealing material of the hollow fiber membrane are not less than 100˚C.
