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.
