  • Publication number: 20260097368
    Abstract: Cleaning-in-place (CIP) systems utilize membrane filters for purifying liquid substances in many industries, including but not limited to, the dairy industry, breweries, pharmaceutical industry, and the food industry. These membrane filters undergo a rigorous cleaning process that despite cleaning can leave foulants on the membranes which hamper filter effectiveness. In addition to the cleaning, enzymes can be applied to the membranes to remove foulants and restore filtering effectiveness. However, introduction of enzymes into these CIP systems can be problematic if enzymes remain after cleaning. This disclosure provides a system and methods to mimic the membrane modules and verify that a correct inactivation procedure occurred. The systems and methods include a separate membrane sample so that no membrane modules need be removed to verify full enzyme inactivation.

  • Publication number: 20250296050
    Abstract: A membrane fouling monitoring and analysis system may be used on a food and beverage membrane operated over a plurality of production periods separated by daily clean-in-place cleanings. In some examples, the system receives data indicative of a flow of one or both of a permeate stream and a retentate stream of the membrane during the plurality of production periods and determines a trend of at least one parameter associated with the data to provide a determined trend. The system may compare the determined trend to a baseline fouling trend and determine if and/or when to perform a deep cleaning on the membrane based on comparison. The system may subsequently execute the deep cleaning on the membrane at the scheduled time.
