  • Publication number: 20180251390
    Abstract: Systems and methods for treating spent process water containing sulfate and calcium ions. A treatment method includes adding sodium aluminate to a volume of the spent process water to form a solid precipitate containing aluminum, calcium, and sulfate compounds such as ettringite (Ca6Al2(SO4)3(OH)12.26H2O). The solid precipitate is removed from the process water by clarifying and/or filtration, yielding a disposable solid waste material and a treated process water having concentrations of sulfate and calcium ions significantly lower relative to the initial concentrations in the spent process water.

  • Patent number: 8486271
    Abstract: Described herein is a cementitious article and a method of making using a water-based manufacturing system that incorporates a closed-loop or partially closed loop water recycling system and an alkali removal process. The system, as such is environmentally friendly, saves resources, such as water and other raw materials, and reduces waste disposal. The system further provides for a cementitious article having a low alkali content. Articles prepared by one or more processes described herein have characteristics that include a low apparent density, high strength and high freeze-thaw performance as compared with an article of the same general formulation but made from a comparative manufacturing system that does not include an alkali removal process. Articles described herein are suitable for use as building products, such as siding, the underlayment panel, board, trim, fascia, roofing, decking, and fence.

  • Patent number: 6391454
    Abstract: Controlled release urea-based feed supplements for ruminant animals and controlled release urea-based plant nutrients are comprised of particles or granules comprised in whole or in principal part of urea or having urea at or on the exterior surfaces thereof, and a moisture resistant interpenetrating polymer network coating on the particles comprised of the reaction products of urea and a polyisocyanate, and the reaction products of polyisocyanate, an alkyd resin having at least one double bond in each repeat unit and an oil having at least one double bond, the double bonds being reactive with one another and with themselves. The coated plant nutrients have a substantially linear rate of release of nutrients to the soil over a controlled period of time, e.g., 30 to 120 days. The coated ruminant feed supplements have a substantially linear rate of NPN release in the rumen over a controlled period of time, e.g., 12 to 24 hours.

  • Patent number: 6203833
    Abstract: Fresh produce is preserved by coating the exterior surface of the produce with a coating composition comprising an aqueous solution of from about 0.5 to about 4 percent by weight of a cellulose derivative, preferably sodium carboxymethylcellulose, from about 0.05 to about 0.5 percent by weight of konjac, and from about 0.03 to about 0.1 percent by weight of surfactant, preferably dioctyl sodium sulfosuccinate. Optional constituents include antimicrobials, plasticizers and antifoaming agents. The coating composition is effective to control respiratory exchange, i.e., the passage of gases, particularly oxygen, ethylene, carbon dioxide and water vapor, into and out of the produce, thereby to control maturation and ripening of the produce.
