  • Publication number: 20150291914
    Abstract: The present invention comprises chlorinated and non-chlorinated alkaline cleaning compositions for removal of proteinaceous and fatty soils at low temperature, i.e. less than 120° F., with little or no deleterious affect on cleaning performance. According to the invention, applicants have found that adding additional alkalinity makes protein removal more difficult and reducing the amount of alkalinity actually improves performance. According to the invention optimized combinations of chlorine and alkalinity components for low temperature cleaning as well as a surfactant system optimized for low temperature fatty soil removal are disclosed.

  • Publication number: 20150197438
    Abstract: The invention provides methods and compositions for reducing the malodorous sulfide gas released by a wastewater treatment system. The method preserves the vitality of waste consuming organisms within the system. The method comprises the steps of: determining the SRP PAA demand of the system, determining the aerobic PAA demand of the system, and adding a composition in an amount such that it is in excess of the SRP PAA demand but is below the aerobic PAA demand. Even though the composition increases the amount of sulfates within the wastewater it reduces the amount of SRP which prevents the malodorous sulfite gas release. The composition comprises at least one percarboxyacid.

  • Patent number: 8772215
    Abstract: The present invention relates to high alkaline-solvent cleaners, cleaning systems and methods for removing polymerized zero trans fat soils. The high alkaline-solvent cleaner of the present invention generally includes one or more soil wetting and cleaning solvent(s) and one or more alkaline wetting and saponifying agent(s) that wets and saponifies the soil. In various embodiments, the cleaners may include, at least one cleaning agent comprising a surfactant or surfactant system and/or a at least one chelating/sequestering/threshold agent. In some embodiments, the cleaners may include one or more components to modify the composition form and/or the application method. All components described above can also be optimized optionally, to provide emulsification of a composition (both as a usable product or a concentrate that can be diluted to form a usable product).
