Abstract
The present invention relates to a filter module comprising an ester-based membrane and at least one boundary member, wherein the peripheral region of the membrane is connected to the at least one boundary member, and wherein the surface of the membrane is saponified in the regions other than the peripheral region connected to the at least one boundary member. Further, the present invention relates to a method of producing such filter module and to the use of such filter module.
Claims16
A filter module comprising an ester-based membrane and at least one boundary member,
- wherein the peripheral region of the membrane is connected to the at least one boundary member, and
- wherein the surface of the membrane is saponified in the regions other than the peripheral region connected to the at least one boundary member.
A method of producing a filter module comprising an ester-based membrane and at least one boundary member, the method comprising the following steps (a) to (c) in this order:
- (a) providing a membrane made of ester and at least one boundary member;
- (b) connecting the peripheral region of the membrane to the at least one boundary member, thereby obtaining a precursor of the filter module;
- and
- (c) saponifying the surface of the membrane in the regions other than the peripheral region connected to the at least one boundary member, thereby obtaining the filter module.
