  • Publication number: 20240009730
    Abstract: A method of analyzing water in a continuous casting process and controlling chemical addition to the water may involve measuring, with a plurality of sensors, at least one characteristic of a water in a plurality of different locations of a water recycle system for the continuous casting process. The continuous casting process can have multiple spray nozzles that spray water on a metal being cast, and the water recycle system may include a gravity settling tank, a filter, and a cooling tower. A processor can determine, using the measured at least one characteristic of the water from the plurality of sensors, a composite water quality value for the water in the water recycle system. A chemical additive can be controllably added into the water recycle system based on the determine composite water quality value.

  • Patent number: 11639883
    Abstract: A filtration apparatus and methods of installing, using, and retracting the same. A filtration apparatus includes a compression gland, a ball valve, and a filter pipe. A distal portion of the filter pipe has one or more filtration holes. The filtration apparatus may be installed in a process pipe and the distal portion of the filter pipe may be disposed within the process pipe. The filter pipe can be easily retracted from the process pipe without interruption of the industrial process. The filtration apparatus can be automatically cleaned by compressed air or water.

  • Patent number: 10676376
    Abstract: Methods of modification of zero-valent iron (ZVI) to improve its performance in removing contaminants from a discharge stream. In some aspects, the methods include contacting ZVI-impregnated disks with solutions containing metal cations such as Ni2+, Cu2+, Fe2+, or Pd2+. In some aspects, a wastewater stream is treated with a metal cation solution, then passed over ZVI. Compositions for treating wastewater include ZVI that is modified with a metal cation solution.

  • Patent number: 8927637
    Abstract: A polymer, a composition, and uses for either are disclosed. The polymer is derived from at least two monomers: acrylic-x and an alkylamine, and has attached to the polymer backbone a functional group capable of scavenging at least one metal. The polymer has a polymer backbone with a fluorescing quantity of conjugated double bonds, thereby providing a method for controlling metal scavenging via fluorescence. These polymers have many uses in various media, including wastewater systems.

  • Patent number: 8632742
    Abstract: Disclosed are methods for controlling, mercury emissions, and more particularly, to methods for controlling mercury re-emissions from a wet flue gas desulfurizer used in a combustion process. A method of controlling mercury re-emission from a combustion process includes measuring either mercury concentration, oxidation-reduction, potential (ORP), and/or sulfide concentration within a scrubber liquor of a wet flue gas desulpherizer (wFGD); correlating the mercury concentration, ORP, and /or sulfide concentration with an amount of mercury re-emission additive required in the scrubber liquor to reduce and/or prevent mercury re-emission to a selected level; and adjusting the rate of addition of mercury re-emission additive into the scrubber liquor to attain the selected level of mercury re-emission.
