Application & Dosage
Key Areas of Application of Membrane Cleaning Acidic Cleaners
- Cleaning of acid-tolerant RO, NF, UF, and MF membranes.
- Removal of calcium carbonate, barium sulfate, strontium sulfate, and iron hydroxide scales.
- Preventive maintenance to minimize pressure drop and restore normalized flow.
- Suitable for use in industrial, municipal, and desalination plants.
Usage Guide of Acidic Membrane Cleaner 75
Preparation of Cleaning Solution
- Use RO permeate or deionized water for dilution.
- Recommended working concentration: *0.3% - 0.5% v/v (≈ 3 L of RXSOL ORG 75 Membrane Cleaner in 1000 L of water).*
Cleaning Procedure
1. System Preparation
- Flush the membrane system with RO permeate or DI water to remove feedwater.
- Isolate the system and drain as required.
2. Solution Preparation
- Prepare the cleaning solution in the CIP (Cleaning-in-Place) tank at * 0.3% v/v.
- Mix gently until homogeneous.
3. Circulation Phase
- Circulate the solution through the membrane system for 30–60 minutes.
- Maintain flow rates recommended by the membrane manufacturer.
- Keep temperature below 35 °C (95 °F) for safe cleaning.
4. Soak Phase (Optional for Severe Scaling)
- Stop circulation and allow the membranes to soak for 1–2 hours.
- Restart circulation for an additional 15–20 minutes.
5. Rinsing
- Thoroughly flush the system with RO permeate or DI water until the rinse water pH is close to feedwater level.
- Resume normal operation only after confirming system stabilization.
Frequency of Use
Apply cleaning in one of the two cases:
- Normalized flow decreases by 10–15%, or
- Differential pressure increases by 15–20%.
Regular preventive cleaning is recommended to avoid irreversible fouling.
Important Notes
- Do not exceed recommended dosage unless advised.
- Always check membrane manufacturer’s chemical tolerance guidelines (pH, temperature, compatibility).
- Dispose of spent solution in compliance with local environmental regulations.
*NOTE: Dosage entirely depends on the system condition and heaviness of scale deposit. Dosage can vary 2-5% also.
