Abstract: A heat exchange apparatus is provided which is formed from at least one multilayer presealed element and at least one monolayer element that are insert molded together. The heat exchange apparatus is provided with an inlet and an outlet for a process fluid and at least one inlet and at least one outlet for a heat exchange fluid. The sealing configuration of the presealed elements and the seal provided by the insert molding effect a seal configuration that causes heat to be transferred between the process fluid and the heat exchange fluid while preventing mass transfer between the two fluids.

Abstract: Water to be purified is passed through a reverse osmosis step to produce a pure water stream and a waste water stream. The waste water is directed to a deionization step to produce purified deionized water which is recycled to the reverse osmosis step. The process directs far less water to waste as compared to conventional reverse osmosis processes. The process also produces water of higher organic and inorganic purity than can be obtained by either reverse osmosis or deionization alone.

Abstract: A disposable separation module is disclosed which is capable of connecting to a fluid processing system in a quick-connect fashion. The module includes a housing containing a separation element with a plurality of fluid connectors on one end of the housing which are parallel to and exclusive of each other. This arrangement provides for essentially simultaneous engagement and fluid tight sealing of the fluid connectors to corresponding mating connectors on the fluid processing system. A retention mechanism is included which retains the entire module in fluid tight engagement by a single action without producing relative motion between the mating connectors.
