Rapid mineral scale removal acid based cleaners for membrane systems.

ORG 75 Membrane Clean MC Acid Cleaner - a highly acidic liquid cleaner developed for effective cleaning of reverse osmosis (RO), nanofiltration (NF), ultrafiltration (UF), and microfiltration (MF) membrane systems that are Acid-Tolerant.
Its formulation is designed to dissolve inorganic scales, metallic hydroxides, and other acid-soluble foulants, restoring membrane performance and extending membrane life.

Application

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.

Dosage

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.
