How to read the matrix: Estimated requirement of Wetting Agent for 100 hours of operation is One 2-pound Bottle with a Unit
Price of .00.
NOTES:
1. Use NSN 6850-01-423-1698 (6.25) to order a 5-day (100 operational hour) Sustainment Package for the 600-GPH
ROWPU. The 5-day Sustainment Package consists of the above items and respective quantities, except for those items
marked in BOLD print which must be ordered separately. Calcium Hypochlorite has a hazardous material rating. RO Elements
are replaced at a less frequent interval than the other components of the Sustainment Package. (See Note 4 for determining
RO Element requirement.) The costs listed 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. Detergent use rate is based on raw water turbidity and the effectiveness of the pre-treatment system. You should not expect
to clean elements every 100 hours. One bottle of detergent should last 500 or more hours.
3. The number of cartridge filters needed is a function of raw water turbidity. For very clear source water, one box will be
generally sufficient for 100 hours. For muddy/silty source water, 50 boxes or more may be needed for 100 hours of operation.
4. RO elements should normally be replaced every 1000-2000 hours. Recommend 8 each be ordered per ROWPU per 1000-
2000 hours of operation. The requirement quantity of 0.8 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.
5. Check AMDF for most current unit price.
6. Requirements in the above table are estimates. Actual requirements may vary depending on quality of source water.
