    摘要： A method for the manufacture of paper comprising the steps of: a) forming an aqueous cellulosic papermaking slurry; b) adding an effective coagulating amount of a coagulant and a flocculant to said cellulosic papermaking slurry, wherein said coagulant is prepared by blending i) an effective coagulating amount of an aqueous conditioned colloidal silica sol with an average particle size within the range of from 1 to 150 nm and wherein the aqueous colloidal silica sol is conditioned by contacting said sol with a strong acid cation exchange resin, and ii) an effective coagulating amount of a cationically-charged water-soluble polymeric coagulant; c) draining said cellulosic suspension to form a sheet; and, d) drying said sheet. The components of the invention are blended together so that addition is simultaneous. The colloidal silica is conditioned by passing over a cationic exchange resin prior to addition of cationic polymer. The term conditioned as used herein refers to the act of passing the colloidal silica over a cationic exchange resin.

    摘要： The invention comprises a method of preventing deposition of oil on steel mill scale particles comprising adding from about 1 part per million to about 500 parts per million of an amine acrylate/acrylic acid copolymer to mill flume water. Once the copolymer is added, deposition of oil onto scale particles is prevented. The recovered mill scale has less than 2% oil by weight on the scale, making it suitable for recycle to the steelmaking process. Oil and water are subsequently separated with a greater percentage of oil being recovered.

    摘要： A system and method for the detection and removal of copper from wastewater streams from semiconductor or printed circuit board manufacturing is described and claimed. The detection system and method involve the addition of a reagent that reacts with copper to quench the fluorophore present, with the decrease in fluorescence being detected by a fluorometer. The reduction of fluorescence is then used to calculate the amount of copper present in the form of Cu+2 ion in the wastewater. The removal system and method involve either the addition of a polymer that reacts with copper to form an insoluble precipitate with said precipitate then being removed by using any technique commonly known in the art; or the use of an ion exchange column to remove the copper from the wastewater stream.
