    Abstract: A disc filtration system comprises a filter element containing microporous plastic discs through which liquid effluent such as wastewater is passed for filtration. The filter disc surface material contains an anti-bacterial agent exposed to the liquid being filtered for inhibiting growth of microorganisms on the exterior of the filter element. The exposure to the anti-bacterial agent inhibits microorganism growth to an extent that prolongs the useful operational filtration cycle life of the filter between backwashing cycles. The invention applies to disc filters having automatic backwashing and manually operated disc-type filters.

    Abstract: The present invention includes a method for filtering flowing fluid so as to remove undesirable particulates and bacterial constituents and fluid filters for performing the method. The method comprising providing an enclosed channel for fluid flow and passing the fluid flow through a filter material (120, 122) disposed within the channel and the filter material comprising a metal alloy consisting primarily of copper (Cu) and zinc and being metal fibers having an average diameter from 12 microns to 150 microns, contact of the fluid with the fibers of the metal fiber wool (120, 122) providing a bactericide effect and inhibiting further propagation of bacteria and particulates from flowing through the filter material. The fluid filters may be a radial-flow fluid filter (10) comprising a multi-perforated pipe (14) and a plurality of overlapping layers of strips of fibrous metal wool (12) including metal wool containing copper (Cu), or an in-line flow fluid filter comprising a fluid channel (124, 222) and a filter material (120, 122) disposed within the fluid channel ((124, 222), wherein the filter material (120, 122) comprises a metal fiber wool of a metal alloy consisting primarily of copper (Cu) and zinc and being metal fibers having an average diameter from 12 microns to 150 microns. A multi-perforated shell (20) of the radial flow fluid filter (10) may have an inner diameter approximately equal to outer diameter of an outermost layer of wool and a tubular metal mesh encompassing the exterior of the pipe (14) between the pipe (14) and the innermost layer of metal wool (12), the tubular mesh being a woven mesh of stainless steel. The metal of the fiber wool layers (12) is a brass alloy having between 50-90 weight % copper and from 10-50 weight % zinc, a preferable density in a range between 0.4 g/cm 3 to 2.5 g/cm 3 , a more preferred density in a range between 0.5 g/cm 3 to about 1.5 g/cm 3 , and a most preferred density of approximately 0.8 g/cm 3 .

    Abstract: Semi-permeable membranes made from synthetic polymers are treated with a non-leaching antimicrobial agent to prevent bio-fouling and bacterial breakthrough. The semi-permeable membranes include a polymeric material and a non-leaching antimicrobial agent that is incorporated into and homogeneously distributed throughout the polymeric material. In one embodiment, the polymeric material is cellulose acetate. In another embodiment, which utilizes thin film composite polyamide membranes (10), the antimicrobial agent is incorporated in a microporous polysulfone layer (14) that is sandwiched between a reinforcing fabric (16) and an ultrathin polyamide material (12). The invention also includes a treatment of flat and hollow fiber semi-permeable membranes made with polysulfones and polyvinylidene fluoride. The membranes may be used in reverse osmosis, ultrafiltration, and microfiltration applications.

    Abstract: The filter assembly has a filter medium (34) provided with end caps (35, 36) that form water-wettable junctions with the filter medium (34). The filter element (34) is encapsulated in a housing (10) which is formed from a plastics material capable of withstanding steam sterilization. This allows the filter element (34) to be steam sterilized in situ and avoids the need for steam autoclaving and aseptic transfer.

    Abstract: A filter has a longitudinal axis with an inner diameter defined by a hollow longitudinally extending center. The filter has fingers extend radially outwardly arcuately from the longitudinal axis. The fingers have base ends near the longitudinal axis and outer edges at extremities spaced from the longitudinal axis. The outer diameter of the filter is defined by the outer edges of the fingers. The filter is formed from a sintered porous molded thermoplastic or another material resulting in a filter more ridig than standard filters. The fingers are spaced apart from one another a predetermined, substantially fixed distance to form slots therebetween sized to capture contaminants therein.
