GENERAL
MF preservation procedures are performed when the TWPS is placed in an extended shutdown (shut
down longer than 54 hours during deployment) or when the TWPS is shut down in preparation for storage
(stand down from deployment).
Preservation is necessary to ensure that biological growth does not become established on the MF fibers
surfaces during the shutdown period. If they are not preserved and a biological film grows on the fibers,
the TWPS will not meet performance requirements when placed back in operation. If the biological
growth is severe enough, the MF modules will require extensive cleaning/soaking and may need to be
replaced.
The caustic used for MF Caustic Detergent Cleaning is used as the preservative for the MF. For an
extended shutdown, the caustic preservative solution is flushed through the MF module fibers once and
discharged into a cleaning waste holding tank. For a shutdown in preparation for storage, residual
caustic detergent cleaning solution left in the MF modules after the completion of the MF Caustic
Detergent Clean procedure serves to preserve the fibers until the next time the TWPS is deployed.
The procedures covered in this work package include:
MF Preservation Flush for Extended Shutdown
MF Preservation in Preparation for Storage (WP0024 procedures must first be performed)
