Working Principle
Our RO Membrane for Industrial Use operates on the principle of reverse osmosis (RO), a proven water purification technology that uses pressure to separate water molecules from dissolved solids, bacteria, and other contaminants. Reverse osmosis works by reversing the natural process of osmosis, where water molecules move from a low-concentration solution (pure water) to a high-concentration solution (contaminated water) through a semi-permeable membrane.
For industrial applications, our membrane uses a semi-permeable TFC layer that allows water molecules to pass through while blocking larger molecules and ions. When feed water is pumped into the RO system under high pressure (15–30 bar), water molecules penetrate the membrane’s ultra-fine pores to form purified water (permeate), while dissolved salts, heavy metals, bacteria, organic pollutants, silica, and other impurities are intercepted by the membrane and discharged as concentrated water (brine).
The key to the membrane’s industrial-grade efficiency lies in its TFC material and spiral-wound design. The TFC layer is engineered to have high water permeability and selective rejection capabilities, allowing water molecules to pass through more easily under high pressure while maintaining a high rejection rate for contaminants. The spiral-wound design maximizes the surface area available for filtration, ensuring high water yield and consistent performance—critical for meeting the large-volume water needs of industrial operations.

Maintenance Guidelines
Proper maintenance is critical to ensuring the long-term performance and service life of our RO Membrane for Industrial Use. Industrial water treatment systems operate under high load and harsh conditions, so following these guidelines will help maximize the membrane’s efficiency, reduce downtime, and lower maintenance costs:
1. Implement Comprehensive Pre-Treatment
Industrial feed water is often heavily contaminated, so pre-treatment is essential to protect the RO membrane. Equip the system with qualified pre-treatment equipment, including sediment filters (to remove large particles), activated carbon filters (to remove chlorine and organic matter), softeners (to reduce scale-forming ions), and ultrafiltration (UF) systems (for colloidal and suspended solids removal). Regularly replace pre-filter elements (every 2–4 months) to ensure the pre-treatment system is functioning effectively, reducing the SDI and turbidity of feed water and preventing membrane fouling.
2. Strictly Control Operating Parameters
Operate the membrane within the recommended parameters: operating pressure (15–30 bar), temperature (5–45℃), and pH (2–11). Avoid exceeding these limits, as high pressure can damage the membrane structure, extreme temperatures can reduce performance, and strong acids/alkalis can degrade the TFC material. Install monitoring systems to track pressure, water yield, and water quality in real time, and adjust parameters as needed to maintain optimal performance.
3. Regular Flushing & Cleaning
Flush the membrane with low-pressure feed water for 15–20 minutes every day to remove contaminants that have accumulated on the membrane surface. This routine flushing prevents the buildup of scale, organic matter, and bacteria, reducing the need for chemical cleaning. For chemical cleaning, perform it when water yield decreases by 10–15% or pressure difference increases significantly. Use only industrial-grade RO cleaning agents: acidic cleaners for scale (e.g., calcium carbonate) and alkaline cleaners for organic or biological fouling. Follow the manufacturer’s instructions for dilution ratios and cleaning time, and rinse the membrane thoroughly after cleaning to remove residual cleaning agent.
4. Shutdown & Storage Maintenance
If the industrial RO system is shut down for a short period (less than 3 days), keep the membrane moist by flushing it daily. For long-term shutdowns (more than 7 days), soak the membrane in a protective solution (1–2% sodium bisulfite) to prevent bacterial growth and membrane drying. Seal the membrane element and store it in a cool, dry environment, away from direct sunlight and freezing temperatures. Before restarting the system, flush the membrane thoroughly to remove the protective solution.
5. Regular Inspection & Monitoring
Establish a regular inspection schedule (weekly or monthly) to monitor the membrane’s performance. Track key parameters such as water yield, desalination rate, pressure, and water quality (using a TDS meter). Record these data points to identify trends and detect potential issues early, such as pre-treatment failure or membrane fouling. Address any abnormalities promptly to avoid further damage to the membrane or the RO system.
6. Avoid Oxidizing Agents
The TFC membrane material is sensitive to oxidizing agents such as chlorine, ozone, and hydrogen peroxide—common in industrial water treatment. Ensure that the pre-treatment system effectively removes these oxidizing agents (using activated carbon filters or dechlorination agents) to prevent membrane oxidation and damage. Do not use oxidizing disinfectants to clean the membrane, as this will degrade the TFC layer and reduce its performance.
