  • Patent number: 6203722
    Abstract: A stabilized lime slurry for treatment of biological solids in sewage. The composition preferably includes 30-36% calcium hydroxide, 10-16% potassium hydroxide, 2-4% potassium chloride, 2-4% magnesium hydroxide, all on a dry basis, and the balance in water. This composition raises the pH rapidly for destroying pathogens, is sufficiently concentrated for economically feasible transportation, and reduces the cost, difficulties and dangers of treating sewage with a lime based composition while providing a resulting product from the sewage treatment process which can be spread upon agricultural soil in a manner which improves soil fertility without introducing undesirable or contaminating materials into the soil.
    Type: Grant
    Filed: October 2, 1998
    Date of Patent: March 20, 2001

  • Patent number: 4376824
    Abstract: A glucose/fructose syrup is produced by enzymatically isomerizing an unrefined starch hydrolysate. The hydrolysate is prepared under controlled liquefaction and saccharification conditions to provide an isomerization substrate wherein the concentrations of calcium ions and non-enzymatically generated ketose sugars are maintained at low levels.

  • Patent number: 4355117
    Abstract: A process is provided wherein a fibrous ion exchange cellulose composite is prepared by agglomerating a hydrophobic polymer and fibrous cellulose and then derivatizing the cellulose to impart ion exchange properties thereto. The process is an improvement over the prior art processes wherein the composite is prepared by agglomerating the polymer with fibrous cellulose which has been converted to ion exchange cellulose prior to agglomeration.
