Title: Membrane separation element
Inventor: IKEDA KENICHI
IPC: B01D63/08
Filed: 1991-12-30
Abstract: PURPOSE:To backwash a separation membrane although a tubular, cylindrical or flat membrane is used by coating a porous support with the separation membrane by heat contraction. CONSTITUTION:A separation membrane 2 is firmly attached to a porous support 1 by heat contraction. Since the integration of the membrane 2 and support 1 is kept even against the internal pressure, the membrane 2 and support 1 act as a composite, and a hoop stress acting on the membrane is relieved as compared with the case where both members are not integrated. Meanwhile, a woven fabric 3 is embedded in the membrane 2 to allow the fabric 3 to act as a tension member, hence the hoop stress is substantially borne by the fabric 3, and the hoop stress is not exerted on the membrane. Accordingly, the hoop stress exerted on the membrane by the internal pressure is reduced or diminished to and backwashing is safely carried out.
