GENERAL
MF Cleaning with RO Acid Cleaning is performed whenever the TWPS is placed in a long-term term shut-
down in preparation for storage. It should also be performed if the TWPS is to be shut down during
deployment for longer than 54 hours and it is not certain how long the TWPS will be shut down before it is
started up again. Cleaning in preparation for storage is performed regardless of the TMP, % Clean, and
% Salt Rejection values. The purpose of cleaning in preparation for storage is to preserve and extend the
useful life of the MF modules and RO elements.
MF cleaning with RO acid cleaning combines the MF cleaning and RO acid cleaning procedures in the
following order:
- MF Backwash
- Acid Cleaning Solution Preparation
- MF Drain
- RO Acid Cleaning
- MF Acid Cleaning
- MF Caustic Detergent Cleaning
