OBJECTIVE
The objective of the Clean In Place (CIP) system is to introduce high pH and low
pH membrane cleaners to the AmeriWater RO+ system at low pressure and high
velocity. This action removes scale and organic contaminants from the RO+
membranes and improves system performance.
CHEMICALS REQUIRED
AmeriClean A (P/N 37-0004) low pH cleaner for removing inorganic scale and
metals from polyamide thin-film composite membranes (1 lb (266 ml) of
AmeriClean A powder is required per membrane cleaning). AmeriClean A
effectively removes the following foulants:
•Calcium Carbonate Strontium Sulfate
•Calcium Sulfate Iron
•Barium Sulfate Metal Oxides
AmeriClean B (P/N 37-0005) high pH cleaner for removing acid insoluble
foulants from polyamide thin-film composite membranes (1 lb (372 ml) of
AmeriClean B powder is required per membrane cleaning). AmeriClean B
effectively removes the following foulants:
•Silt Microbiological
•Colloids Acid Insolubles
•Organics Mucilaginous Material
WARNING: Wear appropriate eye and skin protection when handling the
membrane cleaning chemicals. The cleaners are high and low
pH chemicals and may cause severe chemical burns. Read the
MSDS for further information.
WARNING: Never allow AmeriClean A and AmeriClean B to mix! Mixing
the chemicals will cause an exothermic reaction which may
result in serious injury and/or damage to the equipment! Flush
the system thoroughly and verify that the pH of the reject water
is neutral prior to introducing another chemical!
WARNING: AmeriClean A and B membrane cleaners are for
polyamide
thin-film membranes only and cannot be used on cellulose
acetate membranes.

HIGH pH CLEANING
NOTE: Be sure to remove carbon block filters (if applicable) from the RO before
performing cleaning. Filters will be clogged by cleaning solution if not
removed. Sediment filter may remain in the system.
AmeriClean B is used first for the removal of biological and colloidal foulants.
1. Add 10 gallons (~2 inches
below the top hose connection)
of clean water to the CIP drum
(FIGURE 3). RO+ product
water or deionized water is
recommended if available.
Water with a minimum
temperature at or near 86° F
will provide maximum
effectiveness for the high pH
cleaner.
2. Slowly add 1 lb (1 full bag) of
AmeriClean B to the water in the cleaning drum.
3. Agitate the solution until the powder is completely dissolved. It is important
to make sure all of the powder is dissolved before continuing.
WARNING: Wear appropriate eye and skin
protection when handling the
membrane cleaning chemicals. The cleaners are high pH and
low pH chemicals that may cause severe chemical burns. Read
the MSDS for further information.
4. Connect the CIP pump power cord to a 120 VAC receptacle (GFI
recommended).
5. Place the Flush Valve in “FLUSH” then turn on the RO+ and verify that the
cleaning solution is recirculating and flowing from the drain hose inside the
CIP drum.
6. Allow the cleaning solution to recirculate for a minimum of 50 minutes.
a. Depending on the nature of the fouling, a soak period may be necessary.
If the membranes are not heavily fouled, proceed to step 7.
b. In cases of heavy fouling, turn off the RO and CIP pump and allow the
system to soak for a minimum of 30 minutes.*
* Contact AmeriWater Technical Support or your local AmeriWater dealer for custom cleaning procedures if
necessary.

c. After the soak time, turn on the CIP pump and RO, and allow the cleaning
solution to recirculate again for 30 minutes.
7. Disconnect the pump outlet hose from the CIP drum and direct the hose to a
drain. Continue running to drain until the CIP drum is empty (some solution
may need to be manually dumped out of the CIP drum).
CAUTION: Neutralization of the spent cleaning solution may be required by
local regulations. Verify the requirements of local regulations
prior to emptying the cleaning solution into the drain.
8. After removing the spent chemical from the CIP tank, and with the CIP
pump discharge directed to drain, turn on the MRO and allow fresh water to
flow into and through the RO and CIP system for 10 minutes or until the pH
of the water at the pump discharge is neutral (between 6 and 8).
9. Disconnect the pump outlet hose from the CIP and direct it to a drain.
Continue running to drain until the CIP drum is empty (some solution may
need to be manually dumped out of the CIP drum).
WARNING: Never allow AmeriClean A and AmeriClean B to mix! Mixing
the chemicals will cause an exothermic reaction which may
result in serious injury and damage to the equipment! Flush
the system thoroughly and verify the pH of the reject water is
neutral prior to switching chemicals!
NOTE: Under certain conditions the CIP Pump may shut down during
recirculation due to thermal overload. In the event that this should occur,
disconnect the pump from the power receptacle and allow it to cool for
15 to 30 minutes. After the pump has been allowed to cool, it may be
reconnected to the power receptacle and the recirculation continued.
NOTE: The 20” filter housings may trap some left over chemical solution
causing rinse out times to be high. To shorten the rinse time, remove
and dump the filter housing, then reinstall in the system. This allows the
housing to fill with fresh water and reduces time required for rinsing.

LOW pH CLEANING
AmeriClean A is used second for the removal of inorganic scale and metals.
1. Add 10 gallons (~2 inches
below the top hose connection)
of clean water to the CIP drum
(FIGURE 3). RO+ product
water or deionized water is
recommended if available.
Water with a minimum
temperature at or near 86° F
will provide maximum
effectiveness for the high pH
cleaner.
2. Slowly add 1 lb (1 full bag) of AmeriClean A to the water in the cleaning
drum.
3. Agitate the solution until the cleaner is completely dissolved. It is important
to make sure all of the powder is dissolved before continuing.
WARNING: Wear appropriate eye and skin protection when handling the
membrane cleaning chemicals. The cleaners are high and low
pH chemicals and may cause severe chemical burns. Read the
MSDS for further information.
4. Connect the CIP pump power cord to a 120 VAC receptacle (GFI
