  • Manifold plates and fluid treatment arrangements including manifold plates
    Patent number: 8919385
    Abstract: A manifold plate and a filtration arrangement including a manifold plate which comprises a body having a mounting region on the exterior of the body and first and second fluid channels extending within the body. The mounting region has at least one first opening and at least one second opening. At least one first fluid passageway fluidly couples the first opening to the first fluid channel and at least one second passageway fluidly couples the second opening to the second fluid channel. One or more filtration units may be mounted to the mounting region in fluid communication with the first and second openings of the manifold plate.

  • Process for forming a membrane filtration apparatus
    Patent number: 6524513
    Abstract: A filtration apparatus is provided which is formed from multilayer presealed elements and monolayer elements that are insert molded together. The device is provided with a feed port, a filtrate port and, optionally, a retentate port. The sealing configuration of the presealed elements and the seal provided by the insert molding step effect a seal configuration that causes a feed liquid to be filtered to form a filtrate such that the filtrate is not mixed with either the feed or a retentate.
