Membrane Alka Cleaner ORG MC 511 Liq
During the operation of a membrane separation system, organic materials, as well as suspended solids in the incoming water, can accumulate on the membrane surface. The presence of organic materials also provides an environment conducive to microbiological activity, which can result in microbiological fouling. Fouling from these species impedes the flow of water through the membrane. This can result in unacceptably low production, high operating pressure, or an excessive pressure drop in the system, which may lead to irreversible membrane damage. Additionally, accumulation of these foulants on the membrane surface can increase the amount of dissolved material passing through the membrane, resulting in product water of unacceptable quality. Before these foulants can accumulate to a level where product water declines or membrane damage can occur, they should be removed by a clean-in-place (CIP) off-line cleaning. Indications of the need for cleaning include a significant decrease in normalized permeate flow, a significant increase in pressure drop across the system (or individual stage), or an increase in the normalized salt passage, such that product quality is unacceptable. Rx Marine International representative can assist you with monitoring your system and determining when cleaning is advised.
Dilution - The product must be diluted prior to introduction into the membrane system. The recommended dilution for this product is 500 Grams of ORG MC 511 (Membrane Cleaner) per 20 Ltrs of water.
General Cleaning Instructions
The following general cleaning procedure can be followed. For the optimum cleaning procedure for your system, contact
Rx Marine International Representative.
- Inspect cleaning tank, hoses, and cartridge filter. Clean tank and flush hoses if necessary. Install new cartridge filters.
- Fill cleaning tank with RO permeate or DI water. Turn on agitator or tank recirculation pump.
- Slowly add ORG MC 511 (Membrane Cleaner) to cleaning tank 5 Ltrs of product for every 200 Ltrs of water and allow to mix thoroughly.
- Check solution temperature. If solution temperature is lower than recommended level, adjust heating control to provide optimum temperature.
- Check solution pH. The solution pH should be 10 to 11.5 or as recommended by the membrane manufacturer. If pH is too low, adjust pH upward with NaOH, or other chemical as recommended by the membrane manufacturer. If pH is too high, adjust with hydrochloric acid.
- 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 the manufacturer’s recommendation is not available, contact Rx Marine International 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.
- 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 move out of the recommended range, a new solution should be prepared. In any event, a new cleaning solution should be prepared for each stage.
- Rinse with RO permeate before returning system to service.
- When returning unit to service, divert product water to drain until any residual cleaning solution has been rinsed from system.
- Compatible with polyamide thin-film composite membranes
- Optimum results are obtained when used in conjunction with ORG MC 882
- Extremely effective against oils and many other organic compounds
- Excellent results when used to clean biological matter and eliminate biological slime from the membrane surface
- Buffered to maintain an effective pH over a range of dilutions
- Enhanced performance at elevated temperatures
- Liquid cleaner which allows shorter mixing time.
- Low foam formulation
- No adverse effects with repeated use
