Title:
MULTILAYER HOLLOW FIBRE MEMBRANES COMPRISING AMPHIPHILIC COPOLYMERS
Document Type and Number:
WIPO Patent Application WO/2018/041731
Kind Code:
A3
Abstract:
Multilayer single-bore hollow fibre membranes M or multilayer multi-bore hollow fibre membranes M for ultrafiltration applications are disclosed, comprising at least one hollow fibre membrane substrate S comprising a polymer bulk material P1 and at least one functional layer F disposed on at least the inner surface of the hollow fibre membrane substrate S, wherein the functional layer F comprises at least one polymer P2. The hollow fibre membranes may be used in ultrafiltration methods and filtrationmodules, in particularfor the treatment of waste water.
