Abstract
A filtration assembly includes at least one membrane assembly, where the membrane assembly includes a membrane and at least one end cap device. The end cap device is defined in part by a longitudinal axis and extends from a first end to a second end along the longitudinal axis. The end cap device includes an intermediate profile between the first end and the second end, and the second end has a smaller inner diameter than the first end.
Claims19
A filtration assembly comprising:
- at least one ceramic membrane assembly configured to be disposed within a housing, the at least one ceramic membrane assembly includes a membrane and at least one end cap device;
- the membrane extending from a first membrane end to a second membrane end;
- the end cap device disposed at the first membrane end of the membrane;
- the end cap device is defined in part by a longitudinal axis and extends from a first end to a second end along the longitudinal axis, the end cap device defined in part by an inner surface and an outer surface, the end cap having an end port at the first end;
- the end cap device includes an intermediate profile between the first end and the second end, the inner surface having a domed shape at the intermediate profile;
- and
- the first end of the end cap device has a smaller inner diameter than the second end.
