F-260 Acid Detergent for RO Membrane – The Ultimate Solution for Deep Cleaning and Scale Removal

F-260 Acid Detergent for RO Membrane is a high-performance acidic cleaning formulation developed to restore and maintain the efficiency of reverse osmosis (RO), nanofiltration (NF), and ultrafiltration (UF) systems. Designed for safe and effective use across all aromatic polyamide membranes, this product efficiently removes metal hydroxide, calcium carbonate, and inorganic scale deposits that cause membrane fouling and performance decline.

By incorporating F-260 into your membrane maintenance routine, you can significantly extend system life, improve water quality, and reduce operational costs — ensuring consistent and reliable filtration results.

Exceptional Cleaning Power

The F-260 formula features a low-foam, highly effective acidic blend that targets and dissolves stubborn deposits including:

• Calcium carbonate (CaCO₃)
• Iron hydroxide (Fe(OH)₃)
• Aluminum oxide
• Manganese oxide
• Other mineral scales and metal precipitates

These contaminants, if left untreated, can severely clog RO membranes and reduce permeate flow. F-260 penetrates and breaks down these deposits quickly, helping restore the membrane’s original flux and salt rejection properties.

Its optimized pH range (3.0–4.0) ensures a balanced cleaning performance that is tough on scale but gentle on membrane surfaces, maintaining the integrity of the delicate polyamide layers.

Key Advantages of F-260 Acid Detergent

1. Universal Compatibility – Safe for all aromatic polyamide membranes and widely compatible with leading RO system brands such as DuPont FilmTec, Hydranautics, and Toray.
2. Low Foam Formula – Designed for clean, efficient circulation without excessive foaming during CIP (Clean-In-Place) operations.
3. Efficient Descaling Action – Effectively removes calcium carbonate, metal hydroxides, and other inorganic fouling.
4. Reusability – Can be reused multiple times, minimizing chemical consumption and cleaning costs.
5. Liquid Concentrate – Easy to dilute and mix uniformly with water for consistent cleaning performance.
6. Temperature Stable – Effective across a wide temperature range, provided solution temperature does not exceed recommended limits.
7. Eco-Conscious Design – Formulated to reduce chemical waste and extend membrane cleaning intervals, contributing to sustainable operations.

Technical Specifications

Recommended Dosage and Cleaning Procedure

For optimal results, F-260 should be diluted to a concentration of 1–3% (typically a 1:45 ratio with water). The cleaning process should be performed as follows:

1. System Preparation:
   Inspect the feedwater tank, pipelines, and pre-filters. Replace filter elements if necessary to prevent recontamination.
2. Solution Preparation:
   Fill the cleaning tank with RO permeate or deionized water. Add the required amount of F-260 while circulating to ensure complete mixing. Measure the initial pH (target range 3.0–4.0).
3. Cleaning Process:
   Circulate the cleaning solution through the membrane system for 20–30 minutes. Monitor pH throughout the process—if it rises above 4, add more F-260 or acid to maintain effectiveness.
4. Evaluation:
   Once pH stabilizes and no further change is detected, cleaning is complete. For heavily fouled systems, replace the first cleaning batch with a new solution and repeat the process.
5. Post-Cleaning:
   Thoroughly rinse the RO system with clean water to remove any residual cleaning solution before restarting production.

⚠️ Important: Always monitor cleaning temperature and avoid exceeding recommended levels to protect membrane integrity.
