Solution (WP 0014), MF Cleaning (WP 0021), MF Cleaning with RO Acid Cleaning (WP 0024) or MF
Preservation (WP 0026), citric acid is poured into the tank as an initial charge when the tank is set up.
The procedure for adding the citric acid is given by the referenced work packages. After the cleaning
wastes have been discharged into the tank, further neutralization may be accomplished as described.
This section provides the procedures to complete the waste neutralization and for pumping the cleaning
wastewater out of the tank for disposal.
