  • Patent number: 8970829
    Abstract: The invention refers to a fouling detection setup (I) and method for determining the amount of fouling (5) of surfaces (3) of fluid (6) treating devices (2) and/or internal functional components (4) of such devices, which are exposed to said fluid and are subjected to fouling. Fouling detection setups and methods are useful for monitoring the amount of fouling of surfaces, e.g. heat-transfer surfaces and also for monitoring the cleaning procedure of such fluid treating devices and/or internal functional components of such devices. According to the invention the detection setup (I) comprises at least one first sensor (7), with means (9) for measuring the optical transparency T and/or electrical conductive conductivity Q of said fluid (6). The Sensor includes at least one sensitive area (8) that is located nearby and/or within said surfaces (3) and wherein said area is at least temporarily exposed to said fluid (6).

  • Patent number: 8933009
    Abstract: The present invention relates to the field of membrane separation processes and clean in place compositions for cleaning 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. According to the invention, surfactants and polymers useful for this process are unpredictable and specific surfactants, polymers, and combinations of the same are disclosed for use alone, as part of a cleaning composition. Methods of use of the same are also included.

  • Publication number: 20090200234
    Abstract: The present invention provides methods for cleaning surfaces that are sensitive to high temperatures and/or that have pH limitations. Exemplary surfaces to be cleaned using the methods of the present invention include membranes. The methods of the present invention include applying an active oxygen use solution including an active oxygen source to the surface. An activator complex and an alkaline override use solution are applied to the surface, either in combination, or in a stepwise manner, before, after or simultaneously with the active oxygen use solution.
