OPERATING INSTRUCTIONS LC Manual 11/02 Rev. 3 3.5 SHUTDOWN (LESS THAN 4 DAYS) CAUTION If the shutdown is due to a malfunction, be sure to disconnect the electrical power and turn off the water supply before making repairs or replacements. If the system is not to be operated for up to 4 days, the system should be placed in the STANDBY mode. When in this mode the RO system cycles on and off continuously for a user settable duration at a user settable interval until the mode of operation is changed again. This mode will allow the system to return to normal (TANK or DIRECT FEED mode) operation at any time with no adverse affects on the water quality or RO membranes. 3.6 LONG TERM SHUTDOWN PROCEDURE CAUTION CAUTION If the system is to be down for a period longer than 4 days, it is recommended that a biocide be pumped into the membrane elements to prevent biological growth. Failure to store the membranes in a biocide for long term shutdown can cause irreversible damage to the membranes due to bacterial growth. The solution USFilter recommends is a 0.5 to 1.0% solution of sodium bisulfite. For conditions where freezing may be a problem, the solution should also contain up to 18% (by weight) glycerin or propylene glycol. Refer to RO membrane data sheet in Appendix for further information. The following equipment and materials are needed: CIP Cleaning Skid RO Product Water or DI Water Sodium Bisulfite (food grade) Propylene Glycol or Glycerin (if required) Safety Equipment A. Fill the tank on the cleaning skid with the appropriate quantity of RO product water or DI water. Do not use a solution of greater than 1.0% bisulfite. The pressure vessel endcaps will be damaged otherwise. B. Add the correct amount of sodium bisulfite powder to the cleaning tank using the following proportions: 0.5% solution sodium bisulfite - .042 lbs. per gallon 1.0% solution sodium bisulfite - .084 lbs. per gallon If applicable, add the appropriate amount of freeze protection (glycerin or propylene glycol) to the solution at this point. 3-4 USFilter
LC Manual 11/02 Rev. 3 OPERATING INSTRUCTIONS C. Once the bisulfite solution is thoroughly mixed, allow the solution to circulate through the RO unit for 30 minutes. D. Fully close the manual feed water isolation valve and install a Lock-Out device and a Lock Out Tag on the valve. E. If applicable, you may also have to fully close any process valves located in the RO unit product line down stream of the product line to prevent unwanted RO product water from passing this point, and install a Lock-Out device and a Lock Out Tag on the valve. F. Drain the pump and manifold piping. G. Seal all openings to prevent the membrane elements from drying out. H. Tag the RO unit with the date and type of solution the membranes are stored in so that it is properly flushed prior to being put back into service. The RO unit is now ready to be stored. Be sure to follow the Initial Startup in Section 3.2 when ready to put the unit back in service. USFilter 3-5
