摘要： A separation end cap (34) adapted for connecting adjacent separation elements (12) is provided. The end cap (34) may be located at the distal ends of a separation element (12) and is adapted for connection with a permeate tube (18) located within the separation element (12). In one embodiment the end cap (34) includes an inner hub (36) for receiving an O-ring to seal against an inner hub (36) of an end cap on an adjacent separation element (12). The inner hub of the end cap may be spin-welded to the outer surface of the permeate tube (18). A locking structure (52) on an outer hub (48) of the end cap co-acts with a locking structure (52) on an end cap (34) of an adjacent separation element (12) to releaseably lock the end caps and, therefore, adjacent separation elements. The locking structure (52) preferable provides a predetermined axial force on the O-ring (34) to seal the connection between permeate tubes (18) of adjacent separation elements (12). The locking structure may also provide audible and/or visual feedback that the locking of adjacent end caps has been achieved.

摘要： This invention relates to spiral rolled membrane elements having continuous membrane sheets with folds (46, 48) or discontinuous sheets with seals (42, 44) and having permeate flow channels (38) attached to a porous polymeric hollow-core mandrel (31) in a regular and closely spaced array. A means of attaching permeate flow channels (38) having characteristics of a thermoset polymer to a thermoplastic mandrel (31) by means of ultrasonic welding is disclosed. The attaching means permits the attachment of a high density of permeate flow channels (38) per centimeter of mandrel (31) radius. The attaching means permits the flow channels (38) to be regularly located about the circumference of the mandrel (31) so as to facilitate the manufacture of a membrane element having a high degree of roundness. The invention also relates to processes of using the elements. The membrane element is suitable for a wide variety of fluid separations including microfiltration, ultrafiltration, nanofiltration, and reverse osmosis separations of liquids, and separations of gas mixtures.

摘要： New methods and apparatus are described for assessing the integrity of a separation module or filtration system. A principle embodiment concerns use of a transient pulse of challenge species to probe a spiral wound module. The resulting time-dependent concentration of challenge species in the permeate is detected, recorded, and compared to a reference. An apparatus is further claimed for detecting permeate conductivity at multiple points within the permeate collection tube of a spiral wound module. Also disclosed is a process whereby the permeate stream from a filtration system is concentration by a high recovery membrane apparatus prior to measurement of challenge species concentration.

摘要： A process for making a water softening membrane and a process for using the same is described. The membrane is prepared by treating a polyamide reverse osmosis membrane with a strong mineral acid. Preferably, the membrane is then treated with a rejection enhancing agent. The resulting membrane at transmembrane pressures of 50 psi can attain a magnesium sulfate rejection with a 0.2 percent aqueous solution of more than 90 percent with a water flux of more than 610 liters per square meter per day (15 gallons per square foot per day).
