Total Cost of Consumables for 100 hours/5 days of Operation:

*U/l: BT = Bottle, BX = Box, EA = Each, DR = Drum, GL = Gallon, PG = Package, BG = Bag
BOLD: Item must be ordered separately.
How to read the matrix: Estimated requirement for detergent cleaner is one 25-pound drum with a unit price of 2.00.
NOTES:
1. Use NSN 6850-01-423-1699 (33.28) to order a 5-day (100 operational hour) sustainment package for the 3,000-GPH
ROWPU. The 5-day sustainment package consists of the above items and respective quantities, except for those items in
BOLD print which must be ordered separately. Calcium hypochlorite and eyewash additive have a hazardous material rating.
RO elements are replaced at a less frequent interval than the other components of the sustainment package. (See Note 6 for
determining RO element requirement.) The prices above are based on the individual items. The price of the 5-day sustainment
package includes unique packaging costs and is higher than the total of its components. Users may still order individual items,
if required.
2. One box of eyewash additive is required every 30 days. Eyewash additive comes in a box with 4 each, 4-ounce tablets.
Requirement quantity of 0.167 for 100 hours is prorated based on the usage factor for 30 days (600 hours).
3. Detergent use depends on the type of source water. For freshwater, the elements are cleaned every 400 hours. For
saltwater, they are cleaned every 200 hours.
4. Sodium bisulfite is needed only when the ROWPU is shut down for more than a couple of days.
5. The number of cartridge filters needed is a function of raw water turbidity. For very clear source water, one box will be
sufficient for 100 hours of operation. For muddy/silty source water, 50 boxes or more may be needed for 100 hours of
operation.
6. RO elements should normally be replaced every 1000-2000 hours. Recommend 12 each elements be ordered per ROWPU
per 1000-2000 hours of operation. The requirement quantity of 1.2 for 100 hours is prorated based on the usage factor for
1000 hours in order to provide the planner with an average operating cost for consumables for 100 hours.
7. Check AMDF for most current unit price.
8. Requirements in the above table are estimates. Actual requirements may vary depending on quality of source water.
