WARNING: AmeriClean A and B membrane cleaners are for

polyamide

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

membrane cleaning chemicals. The cleaners are high and low
pH chemicals and may cause severe chemical burns. Read the
MSDS for further information.

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!

1. Connect the PUMP FEED end of
the hose (with the female garden
hose thread fitting) to the bottom of
the CIP drum. Connect the other
end of hose to the CIP Pump Inlet.
FIGURE 2 shows the flow direction
arrows on the CIP pump inlet and
outlet.

RETURN

2. Verify that the RO+ is turned off.

3. Connect the RO+ Product Water
Hose to the Female Garden Hose
Thread Fitting on the CIP drum

(FIGURE 1).

4. Connect the RO+ Reject to Drain
Hose to the hose barb fitting on the
CIP drum labeled REJECT
RETURN (FIGURE 1).

5. Connect the RO+ Incoming Tap
Water Hose to the male garden
hose thread fitting on the CIP
Pump Outlet (FIGURE 2).

6. Remove the carbon tank (if
applicable) from the RO+ and

See the RO+ Operation and
Maintenance Manual for detailed
instructions regarding the removal
of the carbon tank.

protection when handling the

FILL TO 2” BELOW

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.

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.

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).

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.

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).

FLUSH AND RETURN TO SERVICE

1. Disconnect the RO+ Product Water For Dialysis hose, Reject To Drain hose,
and Incoming Tap Water hose from the CIP system.

2. Run the RO+ Product Water Hose and the Reject Water To Drain Hose to a
drain.

3. Reconnect the carbon tank (if applicable) to the RO+.

4. Install a new micron filter in the prefilter sump on the RO+.

5. Place the CIP Switch located on the back of the RO+ controller in the OFF
position (if applicable). Reference the RO+ Operation and Maintenance
Manual for detailed instructions regarding the Clean-In-Place Switch.

6. Connect the RO+ Incoming Tap Water hose to a water supply and turn on the
incoming water supply.

7. Turn on the RO+ and place the FLUSH VALVE in the FLUSH position. Allow
the system to run at this setting for 10 minutes.

8. Place the FLUSH VALVE in the IN SERVICE or OPERATION position and
continue running to drain until the conductivity returns to normal (below
setpoint and not in alarm).

9. The RO+ may now be connected to the dialysis machine and returned to
service.
