  • Process for scale inhibition in evaporative desalination units
    Patent number: 4342652
    Abstract: An effective amount of a copolymer of maleic acid or anhydride and allyl sulfonic acid when added to the water to be treated provides increased inhibition of scale formation in evaporative desalination units.
    Type: Grant
    Filed: January 22, 1981
    Date of Patent: August 3, 1982
    Assignee: American Cyanamid Company
    Inventors: Arthur M. Schiller, James S. Balcerski
  • Process useful in the flocculation of phosphate slimes
    Patent number: 4224149
    Abstract: Use of an effective amount of a precipitant or sequestrant for calcium ions improves performance of anionic polymeric carboxylic acid flocculants in flocculating phosphate slimes.
    Type: Grant

    Date of Patent: September 23, 1980
    Assignee: American Cyanamid Company
    Inventors: James S. Balcerski, Arthur M. Schiller, Arthur Snow
  • Preparation of anionic polymers for use as scale inhibitors and anti-precipitants
    Patent number: 4175100
    Abstract: An anionic polymer of acrylamide having a skewed molecular weight distribution such that about 60% of said polymer has a molecular weight of about 500 to 2,000 and about 10% of said polymer has a molecular weight of about 4,000 to 12,000 has been discovered. The process of manufacturing this skewed molecular weight distribution anionic polymer is described. Its use as a scale inhibitor for controlling the deposition of adherent scales on the walls of vessels or pipes, and as an anti-precipitant for keeping alkaline earth cations in solution is also described. The use of the anionic polymer of acrylamide consisting of a skewed molecular weight could be used in recirculating water systems, boilers, and in evaporative and reverse osmosis desalination systems.
