Abstract
A ceramic membrane filtration assembly comprising a membrane assembly extending from a first membrane assembly end to a second membrane assembly end, where the membrane assembly is defined by a membrane assembly length, the membrane assembly including at least one membrane. At least one of the membranes have channels therein, and at least one channel has channel ends. The filtration assembly further includes at least one sealing device coupled with the membrane assembly adjacent to at least one of the first and second membrane assembly ends, where the sealing device has an inner and outer perimeter. The sealing device has a sealing feature disposed along the outer perimeter, and the inner perimeter of the sealing device is sealed with a portion of the membrane assembly.
Claims22
A membrane filtration assembly comprising:
- a membrane assembly extending from a first membrane assembly end to a second membrane assembly end, the membrane assembly comprising a ceramic membrane having channels therein;
- a sealing device coupled with the membrane assembly adjacent to at least one of the first and second membrane assembly ends;
- and
- a bonding material,
- wherein:
- the sealing device has an inner perimeter and outer perimeter;
- the sealing device has a sealing feature disposed along the outer perimeter;
- the sealing device comprises a center ring and structural members that extend from an inner surface of the sealing device to the center ring;
- the structural members do not contact the membrane assembly ends such that a gap is present between the structural members and the membrane assembly ends;
- the sealing device comprises an end surface projection extending from the sealing device in a longitudinal direction;
- and
- the bonding material is present between the inner perimeter of the sealing device defined by the end surface projection and a portion of a side of the membrane assembly along an outer perimeter of the membrane assembly so that the bonding material bonds the inner perimeter of the sealing device defined by the end surface projection to the portion of the side of the membrane assembly along the outer perimeter of the membrane assembly.
A membrane filtration assembly, comprising:
- a housing having a first housing end, a second housing end, and a housing side between the first and second housing ends;
- a membrane assembly in the housing between the first and second housing ends, the membrane assembly comprising a plurality of ceramic membranes, each ceramic membrane having a plurality of channels therein;
- a device comprising a center ring, an outer ring, and structural members extending between the center and outer rings;
- and
- a sealing feature disposed in a recessed portion of the outer ring so that the sealing feature seals the device to the housing side,
- wherein:
- the structural members do not contact the membrane assembly end such that a gap is present between the structural members and the membrane assembly end;
- the device comprises an end surface projection extending from the device in a longitudinal direction;
- and
- a bonding material is present between an inner perimeter of the device defined by the end surface projection and a portion of a side of the membrane assembly along an outer perimeter of the membrane assembly so that the bonding material bonds the inner perimeter of the device defined by the end surface projection to the portion of the side of the membrane assembly along the outer perimeter of the membrane assembly.
