Sodium Thiosulphate Pentahydrate - Sugar Crystals
Part No: RXSOL-37-2031-025
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
- 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).*
- Flush the membrane system with RO permeate or DI water to remove feedwater.
- Isolate the system and drain as required.
- Prepare the cleaning solution in the CIP (Cleaning-in-Place) tank at * 0.3% v/v.
- Mix gently until homogeneous.
- 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.
- Stop circulation and allow the membranes to soak for 1–2 hours.
- Restart circulation for an additional 15–20 minutes.
- 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.
- Normalized flow decreases by 10–15%, or
- Differential pressure increases by 15–20%.
- 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.

|
The product causes corrosion on skin and mucous membranes Pl. Note that In case of discharge of acidic or alkaline products into the sewerage system the pH must be in the range of 6-10 since higher or lower pH values may damage the sewerage system or impair biological dosage treatment plants. So that for maintaining pH we have to add acidic / basic medium neutaliser . For example if pH is less than 6 basic neutraliser is required and if pH is more than 10 acidic nature neutraliser is required. For details of any guideline pl.
