  • Synergistic interaction of weak cation exchange resin and magnesium oxide
    Patent number: 9193610
    Abstract: The present invention relates to methods, apparatuses, and systems for treating water. The methods, apparatuses and systems reduce scaling associated with solubilized water hardness using a sequence of water treatment agents, including a first threshold agent shedding weak cation exchange resin and a second magnesium compound conversion agent water treatment. The system or apparatus and methods according to the invention provide synergistic reduction of hard water scaling and elimination of cementing on the insoluble magnesium compound.

  • Method of removing and preventing redeposition of protein soils using sugar esters
    Patent number: 9089251
    Abstract: A novel approach to the method of removing and preventing redeposition of protein soils on surfaces using sugar esters is disclosed. Protein deposition and streaking and spotting are common on machine washed dishes. Applicants have found a new method of recycling a sump water composition in an automatic dish machine from a first cleaning cycle into subsequent cleaning cycles using a protein-removing/anti-redeposition agent that can remove and prevent redeposition of protein soils on ware washed surfaces.
