Most membrane systems with time lose a level of their original functionality due to the system ageing and becoming scaled with inorganic solids or fouling with organic material.  This will result in a pressure increase, a reduced flow, a decrease in flux or a reduction in filtrate or permeate flow rates.  When the recommended thresholds are reached it is advised to undergo a cleaning in place or a recovery clean to remove the foulants and scalants and return the system to prior operational levels.  This is achieved by mixing chemicals, compounds or enzymes into solution and passing it through the system in a sequence of high pH, low pH and then biocide as needed to remove the foulant and scale in accordance with supplier recommendations.
