1. Fill the tank with the required amount of water.
2. Start the cleaning pump and flush to drain for about three minutes. 3.
Turn off the cleaning pump. 4. Drain the tank.
STEP 3: Cleaning Solution Recirculation

Close the cleaning pump discharge valve.
Connect the product and reject lines to the cleaning tank. Fill the
tank with the required amount of water.
Dissolve the sodium carbonate (Na
2
CO
3
) in the water. Make sure the sodium
carbonate is fully dissolved before proceeding to the next step.
Mix the 30% hydrogen peroxide (H
2
O
2
) into the solution in the tank. Open
the cleaning pump suction valve and bypass valve completely.
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 Table 4-1.
Recirculate the solution through the module for 30 minutes. Some gas will be
produced. In addition, the module pressure drop will increase during this procedure. Turn
off the cleaning pump.
Check pH. Neutralize if necessary. Drain the tank.
STEP 4: Salt Flush To Drain
This salt flush rinses the cleaning solution from the module, and returns the ion exchange resin to the
sodium and chloride forms.
