  • Patent number: 11981583
    Abstract: A sensor system and process that utilizes impedance/conductivity measurements to track the movement of hardness in an ion exchange media. The impedance/conductivity sensor is a vertical, longitudinally directed, axially lengthwise electrode system having electrodes placed within a bed of ion exchange material and separated by water and the ion exchange material. The electrodes generally run parallel to one another. Hard water is introduced to the water softener and softened by the ion exchange material. A hardness gradient is tracked by the sensor, and regeneration is initiated when it is determined that the ion exchange material is depleted or exhausted.

  • Patent number: 9272934
    Abstract: Overburden from surface coal mining in many regions can produce a rain runoff laden with selenium, in the selenate form. This occurs from exposed selenium-containing rocks in the overburden, from which selenate is leached out by the nearly-pure rainwater. The selenium-containing runoff water is caught in ponds. Remediation of the pond water to remove selenate down to permissible levels for discharge to lakes and streams is performed by treatment with sulfur-modified iron (SMI) in a contact bed of an upflow reactor vessel. After a prefiltering step, the pond water is pH-adjusted as needed and pumped through the SMI reactor. The treated water can then be run through an oxidation tank and filtered to remove iron. For extending effectiveness and life of the SMI the contact bed is periodically “fluffed” with a high-velocity upflow of water through the bed, expanding and loosening the contact bed to prevent or break up compacting of the SMI medium.

  • Patent number: 8828731
    Abstract: A method for facilitating removal of mercury from a primary fluid stream of interest which is contaminated with organically-bound, elemental, and ionic mercury species. The stream is analyzed to establish the relative content of the organically-bound, elemental, and ionic mercury species present therein by forming a diverted side stream from the primary stream, and passing the side stream successively through three in series filter stages, the first captures organically bound mercury, the second captures elemental mercury, and the third captures ionic mercury. The side stream flow through the filter stages is continued for a predetermined period, and upon conclusion of the period the quantity of mercury collected at each of the filtration stages is determined. This data is then utilized to determine the capacity of the three different filtration stages required to reduce the mercury content in the mam stream to a desired level.

  • Publication number: 20140193514
    Abstract: The invention describes a method to treat an extracorporeally body fluid. The body fluid can include, for example, blood, cerebral spinal fluid and lymph. A first stage of the method applies a treatment to the extracorporeal body fluid. The treatment comprises combining at least one antibody with a CA antigen to produce an antibody-CA antigen moiety. A second stage of the method substantially removes the antibody-CA antigen moiety from the extracorporeal body fluid.

    Abstract: A method of treating water to reduce pollutants comprises mixing an adsorbent reagent with the water to form a water-adsorbant reagent mixture. Thereafter, subjecting the mixture to a liquid-solids separation process that produces treated water and sludge. The method further includes contacting the water or treated water with a living aquatic organism wherein the value of at least one property of the organism is correlated to the concentration of pollutants in the water. This value is evaluated and the method entails adjusting the quantity of adsorbent reagent mixed with the water as a function of the value of the property.
