ORG Clean MC 103 Membrane Cleaner Contains organic acids, detergent builders and chelating agents to make cleaning easily and effectively.

FEED REQUIREMENTS

Feed System - This product should be used in conjunction with membrane cleaning equipment supplied by the manufacturer of the membrane system. If such a system is not present, contact your RX MARINE representative for information on fabricating or obtaining a cleaning system.

Dilution - The product must be diluted prior to introduction into the membrane system. The recommended dilution for this product is one pound (0.45 kg) of ORG Clean MC 103 (Membrane Cleaner) per 5 gallons (19 L) of water (approximately one gallon [3.8 L] of ORG Clean MC 103 (Membrane Cleaner) for each 50 gallons [189 L] of water).

Materials Compatibility - Corrosion-resistant equipment, such as PVC, should be used for the storage and preparation of this product. Pumping materials coming in contact with concentrated or diluted products should also be corrosion resistant.

PACKAGING INFORMATION
ORG Clean MC 103 (Membrane Cleaner) is a liquid material, available in a wide variety of customized containers and delivery methods.Contact your BetzDearborn representative for details.

GENERAL CLEANING INSTRUCTIONS
The following general cleaning procedure can be followed. For the optimum cleaning procedure for your system, contact your BetzDearborn representative.

1. Inspect cleaning tank, hoses, and cartridge filters.Clean tank and flush hoses if necessary. Install new cartridge filters.
2. Fill cleaning tank with RO permeate or DI water. Turn on agitator or tank recirculation pump.
3. Slowly add ORG Clean MC 103 (Membrane Cleaner)  to cleaning tank (1 gal [3.8 L] of product for every 50 gal [189 L] of water) and allow to mix thoroughly.
4. Check solution temperature. If solution temperature is lower than recommended level, adjust heating control to provide optimum temperature. If manufacturer’s recommendation is not available, contact your RX MARINE representative.
5. Check solution pH. The solution pH should be 2.5-3.5 or as recommended by the membrane manufacturer. If pH is too low, adjust pH upwards with NaOH, or other chemical as recommended by the membrane manufacturer. If pH is too high, adjust with hydrochloric acid.
6. Circulate solution through one stage at a time in the direction of feed flow for 30 minutes. Circulate at the flow rate recommended by the
   membrane or system manufacturer. If manufacturer’s recommendation is not available, contact your BetzDearborn representative. Pressure
   should be low enough so that no permeate is produced during cleaning, but always less than 60 psig (4.2 kg/cm2). In cases of heavy fouling, the first return flow (up to 15% of the cleaning tank volume) should be diverted to drain to prevent redeposition of removed solids. For optimum results, each stage must be cleaned separately in a multistage system.
7. If the first stage cleaning solution becomes turbid or discolored, dump the tank and prepare a fresh cleaning solution before proceeding. If solution pH or temperature moves out of the recommended range, a new solution should be prepared. In any event, a new cleaning solution should be prepared for each stage.
8. Rinse with RO permeate at 20°C (68°F) minimum before returning system to service.
9. When returning unit to service, divert product water to drain until any residual cleaning solution has been rinsed from system.
