The PROC series, with the core positioning of "high desalination rate, high chemical stability, suitable for complex water quality", is a high-performance composite reverse osmosis membrane specially developed for complex water treatment scenarios. Unlike conventional water treatment membranes that are only suitable for clean water sources, the PROC series focuses on solving the pain points of low desalination efficiency, poor chemical stability and easy damage when dealing with complex water quality (such as high salt, high organic matter, strong acid and alkali). It adopts advanced modified polyamide composite membrane preparation technology, optimizes the membrane structure and surface properties, enhances the selective separation ability of salt ions while improving chemical corrosion resistance, and can maintain stable operation in complex water environments with large fluctuations in water quality and chemical composition, becoming a reliable core component for complex water treatment projects.
2. Application Scenarios

The PROC series is mainly used in complex water treatment scenarios that have high requirements for desalination and chemical stability, with clear pertinence. In industrial production, it is widely applied to high-salt wastewater treatment in chemical, petrochemical, printing and dyeing industries, realizing wastewater recycling and reducing environmental pollution; it is also used in process water purification in pharmaceutical, electronic and other industries, ensuring that the water quality meets production standards. In environmental governance, it is used to treat polluted surface water and groundwater with complex components, removing salt ions and harmful organic pollutants to restore water quality. In arid and semi-arid areas, it is suitable for high-concentration brackish water treatment with unstable water quality, providing usable water for production and living. In addition, it can be used in emergency water treatment scenarios such as industrial accidents and natural disasters, showing strong adaptability to complex water sources.

Second, it has excellent chemical stability, can resist the corrosion of strong acid, strong alkali and organic solvents in complex water, and is not easy to degrade or damage, ensuring long-term stable operation. Third, it has strong adaptability to complex water quality, can adapt to large fluctuations in water quality, salt content and organic matter content, and does not affect the desalination effect and service life. In addition, it has good anti-fouling performance, the modified membrane surface can reduce the adsorption of impurities, reduce cleaning frequency, and has the advantages of high flux and low energy consumption, balancing treatment efficiency and energy saving.
5. Application Procedures
The application procedure of the PROC series is standardized and easy to operate, divided into six steps. First, conduct targeted pretreatment of raw water according to its complex characteristics, including filtration, sedimentation, disinfection and anti-scaling treatment, to remove large particles, colloids and harmful organic substances, avoiding membrane fouling and chemical damage. Second, install the PROC membrane module correctly according to system design, ensure tight pipeline connection and no leakage. Third, start the water treatment system, adjust operating pressure, temperature and recovery rate to the standard range, and conduct 2-3 hours of trial operation to check system stability and water quality. Fourth, during formal operation, regularly monitor desalination rate, membrane flux, pH and other indicators, and record operation data. Fifth, conduct chemical cleaning when membrane flux decreases by more than 20% to restore performance. Finally, shut down regularly for maintenance, check membrane modules and replace aging parts if necessary.
6. Quality Standards
The production and detection of the PROC series strictly follow international standards (such as ISO 20466:2024) and relevant national standards. Raw materials adopt high-quality modified polyamide composite materials, which are non-toxic, environmentally friendly and corrosion-resistant. Production is carried out in a 100-level clean workshop, with strict control over each link from material mixing to membrane curing to ensure uniform membrane pore size and stable performance. Finished product detection includes desalination rate, chemical stability, flux, anti-fouling performance and other items; each membrane is vacuum-sealed with protective liquid and tested qualified before leaving the factory, ensuring product quality and reliability.
7. Working Principle
The working principle of the PROC series is based on reverse osmosis, optimized for complex water treatment. Under high pressure higher than the osmotic pressure of complex water, the semi-permeable membrane of the PROC series selectively allows water molecules to pass through, while intercepting salt ions, organic pollutants and other impurities. Its ultra-small membrane pore size (0.0001-0.001 microns) can effectively block small-molecule salt ions; the modified membrane surface enhances chemical stability, resists chemical corrosion, and reduces the adsorption of organic impurities. At the same time, the special charge property of the membrane surface repels charged ions through electrostatic action, improving desalination effect. The whole process is chemical-free, energy-saving and environmentally friendly, which is an efficient complex water purification technology.
8. Future Prospects
With the increasing severity of environmental pollution and the growing demand for water resource recycling, the market demand for membranes suitable for complex water treatment is growing. The PROC series, with its core advantages, is in line with the development trend of the water treatment industry. In the future, we will optimize membrane modification technology, further improve desalination rate and chemical stability, and enhance adaptability to more complex water quality; develop targeted products according to different complex water scenarios, expand application scope; integrate intelligent technology to realize real-time monitoring of membrane operation and intelligent maintenance, improving operation efficiency and reducing manual intervention, making greater contributions to complex water treatment and water resource recycling.
9. Conclusion
