Abstract: A filtration module is provided which includes a manifold (100), a filtration cartridge (104) and a bowl (102) that houses the filter cartridge. The filtration cartridge and bowl are connected to each other to form a unitary construction. The filtration cartridge and bowl are in fluid communication with the manifold in a manner which prevents mixing of a fluid feed to the module and a permeate removed from the module.

Abstract: A membrane support apparatus is provided which includes a top section, a mating base section and a membrane support surface within the mated sections. The apparatus includes a first peripheral seal formed by extension on one of the sections which mates with a groove on the other of the sections, a second seal formed by a smooth surface on either the groove or the extension which mates with a bead on the other of the groove or extension to form a second peripheral seal. The top section and the base section optionally can form a third peripheral seal about the periphery of a membrane on the membrane support surface.

Abstract: An attachment is discosed for retaining a section of a repair panel within an opening defined by a portion of a hollow wall of the type constructed of modern day panels such as drywall, plasterboard, gypsumboard, and the like. The attachment comprises a body member with means on one side thereof to grip a marginal portion of the wallboard adjacent an opening configured to receive a replacement panel correspondingly configured and dimensioned to the opening. Panel support means in the form of a support seat is provided on the opposite side of the body member and configured and dimensioned such that when an attachment is secured along at least two opposed marginal portions of the wallboard adjacent the opening, the panel support means extends inwardly of the opening to support the replacement panel in nestled relation therewithin. In the preferred embodiment two attachments are positioned in adjacent relation along two opposed marginal portions of the wallboard opening.
