  • LITTER POD SYSTEM
    Publication number: 20230172153
    Abstract: The present disclosure provides a litter pod system, and methods of using litter pod systems. In some embodiments, the litter pod system may include a litter pod formed at least partially of a flexible, polymer material, the litter pod defining a substantially flat pod bottom wall with a pod side wall extending upwardly therefrom, and a housing base configured to receive the litter pod, the housing base being formed of a substantially rigid polymer material defining a housing bottom wall with a housing side wall extending upwardly therefrom.

  • Low foaming surfactant compositions useful in highly alkaline caustic cleaners
    Patent number: 6277801
    Abstract: Highly alkaline caustic cleaners used in large scale industrial applications are stabilized and enhanced with improved surface tension reduction and decreased foaming properties through the incorporation of minor amounts of a surfactant composition comprising a alkylether hydroxypropyl sultaine surfactant and a nonionic ethoxylated surfactant.
    Type: Grant
    Filed: October 4, 1999
    Date of Patent: August 21, 2001

    Inventors: Manilal S. Dahanayake, Mark E. Ventura
  • Recovery and reuse of nonionic surfactants from aqueous solutions
    Patent number: 6207058
    Abstract: Contaminated aqueous systems can be cleaned using an ultra-filtration system that allows for high recovery yields of the surfactant employed therein for recycle and reuse. The system employs specific alcohol alkoxylate nonionic surfactants which remain polar and solvated at the higher operating temperatures of the system. The surfactant/contaminant containing aqueous system is ultra-filtered resulting in the surfactant passing through with the permeate at extremely high yields for recovery and reuse.

  • Recovery and reuse of amphoteric surfactants from aqueous solutions
    Patent number: 5919980
    Abstract: Improved surfactant recovery for recycle and reuse upon ultrafiltration of a surfactant-containing aqueous solution can be obtained using a betaine or amide oxide amphoteric surfactant in the aqueous cleaner/contaminant solution. The surfactant passes through the ultrafiltration membrane with the water in the permeate in very high amounts while the contaminants and other undesirable components are held back in the retentate.
