  • Patent number: 12365606
    Abstract: A method and system treating aqueous effluent from an aqueous stream from at least one of a manufacturing facility, compounding facility or municipal water treatment facility. Reductive and/or oxidative chemical species in an aqueous fluid stream decompose natural hormonal or synthetic hormonal contaminants. The method includes: providing a filter material comprising at least one porous carbon support layer and a silicate wool or glass wool layer in direct contact with the at least one porous carbon support layer having distributed halogens or halides within; passing an electric current through the filter material while directing a contaminated aqueous mass comprising natural hormonal or synthetic hormonal contaminants into contact with the filter material; and adsorbing the hormonal contaminants from the fluid mass onto the filter material in the presence of the electric current, and decomposing the hormonal contaminants.

  • Patent number: 10654731
    Abstract: A method and system generate reductive and/or oxidative chemical species in an aqueous fluid stream to disinfect and/or remove contamination. A filter is provided having a filter element of at least two porous carbon support layers and a silicate wool or glass wool layer in direct contact with and between the at least two porous carbon support layers. Electric current is passed through the filter element. A fluid stream containing elemental halogens and/or halide salts is passed through the filter element, distributing halogens or halides within the filter element. contaminants from the fluid mass onto the filter element, thereby disinfecting or removing the contaminants. Oxidizing contaminants from the fluid mass are adsorbed onto the filter element, thereby disinfecting or removing the contaminants.

  • Publication number: 20200115260
    Abstract: Contaminants are filtered from a fluid flow stream and the filter is regenerated by a process including steps of: providing a filter material comprising both carbon and potassium iodide; passing a contaminated fluid stream in contact with the filter material; adsorbing contaminants from the fluid stream onto surfaces in the filter material; passing an electric current through the filter material with adsorbed contaminant thereon; disassociating contaminant from the surfaces of the filter material; and removing disassociated contaminant from the filter material by carrying away the disassociated contaminant in a fluid flow mass.

  • Patent number: 10051866
    Abstract: Contaminants are filtered from a fluid flow stream and the filter is regenerated by a process including steps of: providing a filter material comprising both carbon and potassium iodide; passing a contaminated fluid stream in contact with the filter material; adsorbing contaminants from the fluid stream onto surfaces in the filter material; passing an electric current through the filter material with adsorbed contaminant thereon; disassociating contaminant from the surfaces of the filter material; and removing disassociated contaminant from the filter material by carrying away the disassociated contaminant in a fluid flow mass.

  • Publication number: 20160209423
    Abstract: Provided is a method for predicting, diagnosing or monitoring an infection or condition caused by or associated with one or more microorganisms in a non-human female animal subject, comprising generating a glycosylation profile from a glycan-containing test sample of the subject, determining from the glycosylation profile one or more test values of one or more glycosylation markers of the infection or condition, comparing the one or more test values of the one or more glycosylation markers to one or more threshold values of the one or more glycosylation markers, and providing a prediction or diagnosis of the infection or condition based on the comparison.
