Usage And Application Instructions for Supraclean 8813 

The standard dilution ratio is 25 grams of 8813 per liter of water. 

1. Inspect all cleaning system components to include CIP tank, hoses, and cartridge filters. Flush or replace if necessary. 

2. Fill cleaning tank with RO permeate or DI water. Turn on agitator or tank recirculation pump. 

3. Slowly add Supraclean 8813 to cleaning tank 25 grams of 8813 for every 1 liter of water and mix thoroughly. 

4. The solution should be heated up to max. 40˚C to improve cleaning efficacy. Do not exceed the membrane manufacturer’s temperature limits. 

5. Circulate solution in the same direction as the feed flow. Typical circulation times are 30-90 minutes. 

6. Maximum flow rate per pressure vessel is 152 Lpm for 8-inch elements and 38 Lpm for 4-inch elements. Maximum pressure for cleaning is 60 psig. 

7. In cases of heavy fouling, the first return flow (up to 15% of the cleaning tank volume) should be diverted to drain to prevent redeposition of removed solids. 

8. Rinse with RO permeate before returning system to service. When returning unit to service, divert product water to drain until any residual cleaning solution has been rinsed from system.
