Abstract
A membrane filtration module is disclosed for use in fluid processing systems in which all active connections between the module and the fluid processing system are located only on one end of the module. A central flow conduit within the module directs all of the flow of liquid from one of the connections to the opposite end. In this manner, dead volume is essentially eliminated as the flow pattern causes the liquid to sweep all the volume within the module while still providing for easy installation and replacement by virtue of having all of the active connections on only one end.
