Clean-in-place (CIP) is a method of cleaning the interior surfaces of pipes, vessels, process equipment, filters and associated fittings, without disassembly. Up to the 1950s, closed systems were disassembled and cleaned manually. The advent of CIP was a boon to industries that needed frequent internal cleaning of their processes. Industries that rely heavily on CIP are those requiring high levels of hygiene, and include: dairy, beverage, brewing, processed foods, pharmaceutical, and cosmetics.

Membrane monitoring and clean-in-place control systems and techniques

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.
