Do not run a sanitization solution through the system when DC power is
applied to the VNX module.
The sanitization procedure for Peracetic Acid involves five steps:
1. An initial salt flush
2. A water flush
3. The Peracetic Acid cleaning
4. A second salt flush
5. A final water flush
STEP 1: Initial Salt Flush To Drain
This initial 5% NaCl rinse removes any metal ions, particularly calcium and magnesium
ions, from the module.
Chemicals needed for Step 1 (5%NaCl):
VNX50-HH
Water (RO permeate or CEDI product)
180 gal (675 liters)
Sodium chloride (NaCl)
75 lbs (34.2 kg)
NOTE:
The following cleaning procedures are based on the piping setup shown in Figure
1. Follow the instructions in Section 6.5 to prepare the VNX system for cleaning or
sanitization. Make sure that the cleaning tank drain valve is closed.
2. Fill the tank with the required amount of water.
3. Dissolve required amount of sodium chloride (NaCl) in the tank water.
4. Open the cleaning pump suction valve and bypass valve completely.
5. Divert the product and reject to drain
6. Start the cleaning pump. When chemicals are well mixed, gradually open the
cleaning pump discharge valve while closing the bypass valve to adjust the product
and reject flow rates to the values given in Section 6.5.
7. Flush the salt solution to drain for about 3 minutes.
8. Turn off the cleaning pump.
9. Drain the tank.
STEP 2: Water Flush To Drain
Water flush rinses the salt solution from the module before cleaning solution is introduced.
Chemical necessary for Step 2
:
VNX50-HH
Water (RO permeate or CEDI product)
180 gal (675 liters)
1. Fill the tank with the required amount of water.
