Sir, I bow to and respect your expertise on the mad dog but the additives used to scavenge traces of water in jet fuels do not dessicate in the manner you suggest.

What was once a smattering of tiny manageable crystals of ice is quick becoming larger chunks that cannot always pass cleanly through the system.
The additives used are usually alcohol based derivatives of ethoxy ethane which use their OH groups to act as chemical bridges - using their OH groups, to Hydrogen Bond to the water molecules and simultaneously Van der Waals bond -with the rest of their structure, to the hydrocarbon fuel molecules.

Net effect of all this chemistry in action is to pull the water into solution in the fuel and not repeat not to accrete it into solid phase lumps.

Hope this helps.
