Remove product and reject outlet lines from the cleaning tank, and direct to drain. Fill
the tank with the water.
Dissolve the sodium chloride (NaCl) in the water.
Start the cleaning pump and flush through the module to drain for about three
minutes.
Turn off the cleaning pump. Drain
the tank.
STEP 3: Water Flush To Drain

Close the pump discharge valve. Keep product and reject lines directed to drain and
disconnect the cleaning equipment from the module.
Turn on the feed water supply to the system. Slowly open the feed valve to allow RO
product water to flow through the module to drain.
After flushing all residual cleaning solutions from the system, follow the initial
start-up procedures in Section 3.5 of this manual. Start without the DC power
applied to the VNX module for five minutes and then restore normal DC power.
4.3.2 Cleaning with 5% Brine/1% Caustic Solution
Sodium Hydroxide is a corrosive chemical. Wear safety glasses, gloves, and
protective clothing when using this or any corrosive chemicals.
A 5% sodium chloride (NaCl)/1% sodium hydroxide (NaOH) solution works well for removing
organic foulants from the module. Use this solution for both routine cleaning and removing
organic foulants.
This procedure involves two steps:
Optional Initial salt flush - (perform if module resin may contain hardness)
1. Brine/caustic cleaning.
2. Water flush.
STEP 1: Cleaning Solution Recirculation
This step removes organic foulants from the module.
