Fighting permeability loss with a revised recovery cleaning schedule

This paper analyses the impact of a revised cleaning schedule based on the permeability of the membranes and the financial impact of increased chemical usage. A side-by-side comparison was conducted on the trains using the original cleaning schedule versus a revised schedule. The process data showed that if the plant had continued following a normal cleaning strategy, the average DBP TCP would have decreased by 1.52% compared to the enhanced strategy which achieved an average DBP TCP increase of 1.72%. The delta between the two values shows the potential in recovering permeability with an enhanced schedule.
