1. OBJECTIVE

The objective of the Clean In Place (CIP) system is to is to introduce high pH and

low pH membrane cleaners to the AmeriWater MRO system at low pressure and

high velocity. This action removes scale and organic contaminants from the

MRO membranes and improves system performance.

2. CHEMICALS REQUIRED

AmeriClean A (P/N 37-0004) low pH cleaner for removing inorganic scale and

metals from polyamide thin-film composite (3 lb (800 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 (3 lb (1,110 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 pH and low

pH chemicals that 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.

3. SET UP

1. Remove the hoses and pump from the CIP tank (pump, hoses and fittings

are shipped inside the tank from the manufacturer).

2. Rinse the CIP tank and hoses with clean water to remove any debris or

contamination after un-packing or after the CIP system has been in

storage.

3. Install two of the long hoses into the upper ports on the tank by screwing

the 1” pipe thread adapter that is on the end of the hose into the pre-

mounted bulkhead fitting. Use two to three wraps of Teflon tape to aid

installation and to seal the pipe threads.

4. Install the third long hose into the outlet of

the pump (the outlet is the port facing

upward on the pump).

5. Install the short hose (approximately 2’ long)

into the pump inlet (the port at the end of the

pump that is facing horizontal).

6. Connect the pump inlet hose to the fitting at

the bottom of the CIP tank using the cam-

lock connector.

7. Turn off the MRO before connecting the CIP2 system or breaking any

water lines.

8. Choose the correct fittings supplied with the CIP2 system that will mate to

the INLET, REJECT, and PRODUCT ports of the reverse osmosis system

to be cleaned, and install them.

9. Connect the CIP pump outlet hose to the reverse osmosis water INLET

only.

WARNING: If the PRODUCT hose (PERMEATE) is momentarily pressurized due

to an incorrect connection (the CIP in reverse flow), the membranes

will be destroyed.

NOTE: When connecting the CIP2 to an AmeriWater MRO 3, 4 or 5, the existing

MRO hoses (one ¾” hose and two ½” hoses) will need to be cut about 12” from

the hose ends opposite the MRO. Install the Cam-Lock male/female connector

pair using the included hose barbs and hose clamps. Be sure that the Cam-Lock

connectors are “gendered” in such a manner that the hoses can be connected to

the correct fittings on the CIP2 tank (see below).

10. Connect the REJECT AND PRODUCT hoses to the CIP hoses near the

top of the CIP tank (hoses may be connected in either orientation).

11. Verify that all connections are made and are watertight.

4. INSTALLATION DIAGRAM

Fittings are provided to fit the AmeriWater MRO3, 4, 5, MROX & MROZ models,

AmeriWater Industrial RO systems, and other common RO systems. Select the

correct fittings (fittings included) to mate to the RO system at your facility.

5. 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.

CAUTION: Do not to allow any cleaning solution to enter the PRODUCT

line going to the storage tank (if applicable).

1. Fill the CIP tank with RO product water (or softened water) to about 25”

deep in the tank. Water at 25” deep in the tank is approximately 27 gallons.

Water should be at or near 86°F for maximum cleaning effect.

2. Slowly add 3 lb (1,110 ml) [3 full bags] of AmeriClean B powder to the

water in the cleaning tank.

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 and low pH

chemicals and may cause severe chemical burns. Read the MSDS

for further information.

4. Open the valves that are connected to the CIP INLET, PRODUCT, and

REJECT hoses to permit flow from the CIP2 through the RO and back to the

CIP2 only. The MRO should be turned off (STANDBY) at this point.

5. Connect the power cord of the CIP2 pump to a 120 VAC receptacle and

allow the solution to begin circulating.

6. Remove the rear cover on the MRO.

7. There is a toggle switch on the backside of the controller. This switch

allows the MRO to operate with the CIP2 connected without sending the

system into an alarm condition. Move the toggle switch to the “ON” position.

8. Close the rear cover on the MRO.

9. Switch the Flush Valve on the RO from “Operate” to “Flush”.

10. Turn on the MRO and verify that the cleaning solution is recirculating and

flowing from the drain hose inside the CIP tank.

11. 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 11.

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.

12. Disconnect the pump outlet hose from the CIP tank and direct the hose to a

drain. Continue running to drain until the CIP tank is empty (some solution

may need to be manually dumped out of the CIP tank).

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. Use an approved waste container for chemical waste

disposal if required.

13. After removing the spent chemical from the CIP2 tank, and with the CIP2

pump discharge directed to drain, turn on the MRO and allow fresh water to

flow into and through the RO and CIP2 for 10 minutes or until the pH of the

water at the pump discharge is neutral (between 6 and 8).

14. Proceed to the low pH cleaning.

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: 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.
