Abstract
A tangential flow filtration apparatus which utilizes a single manifold formed of manifold segment or manifold segments to introduce liquid to be filtered into the apparatus and to remove a filtrate stream and a retentate stream from the apparatus is provided. A plurality of filtration modules are stacked between the manifold and a plate. Holes and sealing means are provided within the filtration modules to effect flow of the filtrate, retentate and incoming liquid through the stack and manifold while preventing admixture of the filtrate with the retentate or the incoming liquid. All manifold segments with the exception the most downstream manifold segment or most upstream manifold segment from the point of introducing incoming liquid must have a filtrate to exit from both ends of the manifold segment. The most downstream or the most upstream manifold segment also can have filtrate exits from both of its ends.
