At optimum conditions measured in controlled envi-
ronment with deionized water, between 30% and
50% of the original permeate flow rate was lost be-
fore the element performance had stabilized after
repeated heat treatments (over 90% of this flow
reduction occurred during the first heat treatment).
With the loss of permeate flow rate, the salt rejec-
tion increases. The rate of cooling and heating was
not more than 5C (41°F) per minute, and the differ-
ential pressure drop per element did not exceed 2
psi.
Pilot testing based on the criteria noted above will
give the best operating parameters for any specific
application.
