I would check your cleaning procedure. Were pH's maintained in the correct range through out the CIP. Any problems with the chemical feed pumps. Were the chemicals mixed properly?
If the CIP was good, there is likely more fouling than expected and soak time, air scour, ect...will need to be adjusted.
Did the feed water change? Could you have a new kind of fouling.
Check with the manufacture

Thanks Mark
Normaly we start with biocide
Then we use high ph 11.4-11.7
Recyclation and sock 1hr each 5 tims
Then we use low ph 3.5 - 2.3
Same as high ph procedure
And between each slution there is flushing step
Also we dump the first water of each slution
Am wondring if the wither temp is effcting also
