Why Perform a Membrane Cleaning Study?

Membrane Cleaning studies are an essential tool for ensuring a successful outcome when cleaning a membrane system. The use of inappropriate membrane cleaning chemicals or an unsuitable cleaning protocol can be a waste of money and valuable time.

AWC^® can perform membrane cleaning studies to identify the best cleaning protocol and most effective cleaning chemicals for a particular fouling situation. One lead element from the first stage and one tail element from the final stage are usually supplied.  AWC^® engineers will then perform a separate cleaning study on each of the elements to determine the best cleaning pH, circulation and soak times, temperatures, and of course, the most appropriate cleaning chemicals for the foulants on the supplied membranes.

The cleaning study involves a performance test after each cleaning step, providing valuable data about the cleaning efficacy at those conditions. The performance test also provides information about membrane salt rejection and helps to identify other operating issues.

AWC^® guarantees that the results of a full-scale CIP will be as good as those of the cleaning study so long as the same procedure and cleaning chemicals are applied.
