MEMBRANE BIOREACTOR WITH COMPOSITE HOLLOW FIBRE MEMBRANES WITH COMPATIBLE BRAIDED SUPPORT FILAMENTS |
摘要 |
A filtering membrane has a supporting structure comprising filaments and is coated with a dope to produce a polymeric membrane layer. Some or all of the filaments comprise a second polymer that is soluble or swellable in a solvent of the dope. The supporting structure may be braided with yarns. One or more yarns may comprise filaments comprising the second polymer. In one example, a braided tubular support is coated with a dope based on PVDF in NMP. Some or all of the yarns of the braid are made of bi-component core-sheath PET-PVDF filaments. With as few as 4% of the yarns in the braid made of the bicomponent filaments, peel strength and pull force of the membrane is improved relative to a braid made entirely of PET yarns. In experimental examples, unpeelable composite membranes were produced. The membrane may be used, for example, for water or wastewater filtration applications. |
