摘要:
A receiver for a cassette filter housing having an upper housing surface. The receiver comprises an arrow shaped elongated member having ends. The elongated member may be parallel with an upper surface of the cassette and may include a base portion attached to the upper housing surface the cross-section of which is a substantially planer segment extending to the upper surface. The elongated member includes an upper receiver portion having at least one cavaliered retaining surface. The receiver includes a first reinforcement member extending outward from the base portion adjacent one of the ends of the elongated member and perpendicular to the elongated member, and a second reinforcement member extending outward from the base portion adjacent the opposite end of the elongated member and perpendicular to the elongated member the reinforcement members affixed to the base portion and the upper housing surface.
摘要:
A method for forming and immobilizing small particles on a filter substrate using a first and second polymer solution, a solution of sodium bromide and a solution of a metal salt. The method adjusts the pH of at least one of the first and second polymer solutions, immersing the filter substrate in the first polymer solution and immersing the filter substrate in the second polymer solution. The method includes repeating the steps of immersing the filter substrate in the first solution and the second solution alternately until desired number of layers is achieved. The method allows for the filter substrate to be immersed in the solution of the metal salt and subsequently in the solution of sodium bromide.

The present invention is directed to a composite filter medium having a pH altering material that can raise the pH of an influent such that microbiological contaminants in the influent remain substantially negatively charged such that a positively charged medium within the composite filter medium can more effectively capture the microbiological contaminants.
摘要:
A filter base for releasably connecting to a complementary mating filter housing assembly comprising a base platform having fluid ingress and egress ports and a floating lock in sliding communication with said base platform having a bottom surface, a top surface, and longitudinal and lateral sides. The floating lock includes spaced protrusions, drive keys, or fingers on said longitudinal sides extending laterally inwards, including at least one shaped protrusion, finger, or drive key for slidably contacting said complementary mating filter housing assembly. The at least one shaped protrusion, finger, or drive key includes an angled face exposed towards the bottom surface, and an edge or wedge opposite said angled face for releasably securing said complementary mating filter housing assembly.

A process for making nanofibers includes preparing a fluid suspension of fibers, shear refining the fibers to create fibrillated fibers, and subsequently closed channel refining or homogenizing the fibrillated fibers to detach nanofibers from the fibrillated fibers. The shear refining of the fibers in the fluid suspension generates fiber cores having attached nanofibers. The closed channel refining or homogenizing of the fibrillated fibers is initially at a first shear rate and, subsequently, at a second, higher shear rate, to detach nanofibers from fiber cores and to create additional nanofibers from the fiber cores. The fiber suspension may flow continuously from the shear refining to the closed channel refining or homogenizing, and include controlling the rate of flow of the fiber suspension from the shear refining to the closed channel refining or homogenizing.

The present invention presents a filtration system with an integrated manifold valve. The filtration system employs only one pivotal component - the pivoting of the manifold. The manifold valve includes a dual aperture design for a two-fold alignment scheme with the ingress and egress lines of the fluid source. The invention is free of multi-component rotary valve with internal, rotatable parts, or an activation component, such as a handle, for initiating the rotary valve, allowing the user to rotate the rotational components thereof. The reduction in moveable components in this design reduces the likelihood of failure and increases the reliability of the filtration system.
