摘要： Disclosed is a shell side contactor which can be used to form ozonated water. The contactor includes a shell and a plurality of porous perfluoroalkoxy resin thermoplastic hollow fibers that are potted at each end of the shell. The perfluoroalkoxy resin hollow fibers can be unskinned, skinned on their inner surface, or skinned on their outer surfaces. The contactor is provided with a spacer that spreads the hollow fibers adjacent an inlet to the shell, thereby permitting liquid flow at desirably high flow rates with acceptable pressure drop through the shell. The mass transfer efficiency of the contactor can be enhanced by jetting water into the fiber bundle and introducing gaps into the bundle.

摘要： Disclosed is a shell side contactor which is highly efficient for forming relatively high concentration of ozonated water comprising a shell containing perfluoroalkoxy resin thermoplastic hollow fibers used as a porous barrier. The perfluoroalkoxy resin comprises a copolymer of tetrafluoroethylene and perfluoroalkyl vinyl ether or a tetrafluoroethyl-co-hexafluoropropylene (FEP) copolymer. The perfluoroalkoxy resin hollow fibers can be unskinned, skinned on their inner surface or skinned on their outer surfaces. The device is provided with spacer means for separating unpotted hollow fibers adjacent an inlet to the shell, thereby permitting liquid flow through the shell at desirably high flow rates with acceptable pressure drop through the shell.

摘要： A filtration cartridge having a housing with an inlet and an outlet and a filtration membrane contained within the housing and located between the inlet and the outlet is described. The membrane is sealed in such a manner that all fluid must flow through the membrane between entering the inlet and leaving the outlet of the housing. The entire cartridge, housing, membrane and any other components are all formed of one or more perfluorinated thermoplastic resins. These resins preferably are PFA, MFA, FEP and blends thereof. The membrane may be in the form of hollow fibers, wound fibers such as in a depth filter, or a flat sheet which may be formed into various configurations such as spiral filters, pleated filters, spiral pleated filters, disks and the like. These cartridges provide an inert, high temperature and acid/oxidative chemical resistant filter having properties similar to that of PTFE resins.

摘要： The present invention relates to a method and apparatus for forming agarose or cored agarose beads. The process involves dissolving/gelation the agarose in a suitable liquid, mixing it with a hydrophobic liquid to form an emulsion and maintaining that emulsion at a temperature equal to or greater than the gelation point of the agarose, passing it through a static mixer to create agarose droplets and solidifying the agarose droplets in a second bath of hydrophobic liquid. The beads can then be washed and used or further processed to crosslink the agarose and/or add various functionalities on to the agarose. Another method for solidifying the agarose droplets is by using a heat exchanger to cool the stream continuously after it exits the static mixer. A similar process is used for the “cored” beads except cores, preferably in bead form, are introduced to the agarose before it enters the first hydrophobic liquid so that the agarose forms a coating on the cores. A similar process with either agarose beads (made by this or another process) or cored agarose (made by this or another process) can be used to add multiple layers of agarose on to the existing beads. An apparatus for running the process is also disclosed.

摘要： The present invention relates to an asymmetric chromatography media suitable for separations applications, particularly as packed bed, fluidized bed or magnetized bed chromatography media. In certain embodiments, the asymmetric chromatography media comprises asymmetric particles, preferably beads, having at least two distinct, controlled pore size distributions. Preferably one of the distinct pore size distributions is in an internal region of the particle, and the other is in an external region or coating on the particle. These distinct pore size distributions can be modified with uniform or alternatively unique functional groups or mixtures of functional groups. The present invention allows for the control over pore size distribution within an asymmetric porous particle by providing a distinct internal region, preferably in the form of a bead, and a distinct external region, preferably in the form of a coating on the bead.
