  • Publication number: 20190099720
    Abstract: Disclosed are membrane separation cleaning processes and clean in place compositions for such membranes. The cleaning compositions can remove proteins, fats, and other food, beverage, and brewery based soils and offer an environmentally friendly alternative surfactant system to NPE. Branched extended chain PO/EO nonionic surfactants with certain characteristics may be used to provide superior cleaning to membranes. The specific surfactants may be used alone or in combination. In some embodiments, the surfactant package is used as part of a cleaning composition.

  • Publication number: 20180168150
    Abstract: Peroxyformic acid compositions for treatment and removal of biofilm growth and mineral deposits on membranes for energy services applications are disclosed. In particular, peroxyformic acid compositions are generated in situ or on site generation for the reduction and prevention, of biofilms and the mitigation of mineral buildup on the membranes. The compositions according to the invention are compatible with the membranes under application of use conditions.

  • Patent number: 9677031
    Abstract: A catalyzed highly alkaline cleaning composition for cleaning stainless steel and other surfaces, namely those treated in clean-in-place processes, is disclosed. The composition comprises gluconic acid or salt thereof (e.g. gluconate) to serve as a corrosion and stain inhibitor for the high alkalinity compositions. The composition retains the cleaning and corrosion prevention properties of conventional clean-in-place solutions while being less expensive to produce.
