These membranes have been cleaned, tested, preserved, bagged (vacuum sealed), boxed and stored in our temperature controlled warehouse. Normalized test results are showing rejection rates greater than 98.0% and flows +- 20% of original manufacturer's specification. Membranes were used in a tertiary application and should be used for industrial applications only. NOTE: Post-cleaning test results are based on a controlled environment; actual field results may vary. OEM data sheet below represents new membrane specifications.
