ORG 75 Membrane Clean MC Acid Cleaner

Frequently Asked Questions FAQs on Membrane Cleaning Liquid

Q1. What is ORG 75 Membrane Cleaning Acid used for? ORG 75 is an acidic membrane cleaner designed to remove inorganic scales, carbonates, sulfates, and iron deposits from RO, NF, UF, and MF membrane systems that are acid-tolerant.   Q2. Why is the recommended dosage only 0.3%? Even at a low concentration (~0.3% v/v), it provides sufficient acidity to dissolve mineral scales without exceeding the pH limits recommended by membrane manufacturers. This ensures safe but effective cleaning.   Q3. How often should I clean with ORG 75 Membrane Cleaning Acid? Cleaning is recommended when:

• Normalized permeate flow drops by 10–15%, or
• Differential pressure rises by 15–20%.

For preventive maintenance, many plants schedule cleaning every 3–6 months, depending on feedwater quality.   Q4. Is ORG 75 Membrane Cleaning Acid compatible with all membranes? It is compatible with most acid-tolerant RO, NF, UF, and MF membranes. However, always verify with the membrane manufacturer’s chemical compatibility guidelines.   Q5. Can ORG 75 Membrane Cleaning Acid  be used at higher concentrations for severe fouling? Yes, in exceptional cases of heavy scaling, higher concentrations (up to 0.5–1.0%) may be used, but only under the advice of the membrane OEM or a water treatment specialist.   Q6. Is ORG 75 Membrane Cleaning Acid  safe to handle? It is a corrosive acidic liquid. Operators must wear gloves, goggles, and protective clothing during use. It is safer than stronger mineral acids like HCl, but still requires standard chemical handling precautions.   Q7. What happens if the cleaning solution is reused? A solution can sometimes be reused if not heavily contaminated, but effectiveness drops as it neutralizes during cleaning. For best results, prepare a fresh 0.3% solution for each CIP cycle.   Q8. How should ORG 75 Membrane Cleaning Acid  be stored? Store in tightly closed HDPE containers in a cool, dry, well-ventilated area, away from strong alkalis and oxidizers. Avoid freezing and direct sunlight. Shelf life is 24 months.
