Just to confirm, by TMP you mean Trans Membrane Pressure, the pressure difference between the feed and the permeate sides of the membrane?
Has the flow (either feed or permeate) changed? Has the temperature changed? Has the TDS of the water changed?
If none of the above have changed, it is likely that you have a fouling or scaling issue going on. Typically this would not be an SDI type issue as that would normally result in greater element differential pressure (feed to concentrate ends of the element), but rather something that is adhering to the surface of the membrane.
Have you seen this before after CIP? How do you determine when to run the CIP? Has the feed water changed in any way?
