1. Product Introduction
SWC6, with the core positioning of "high desalination rate and high boron removal rate", is a high-performance composite reverse osmosis membrane specially developed for scenarios requiring deep desalination and boron removal. Different from ordinary seawater desalination membranes, SWC6 focuses on solving the pain points of low boron removal rate and unstable desalination effect in high-salt water treatment. Seawater and high-concentration brackish water not only contain high concentrations of salt ions (up to 35000mg/L) but also have certain boron content, which is harmful to human health and industrial production. SWC6 adopts advanced aromatic polyamide composite membrane preparation technology and special surface modification process, which enhances the selective separation capacity of salt ions and boron ions while ensuring stable operation. It has excellent tolerance to high-salt, high-pressure and harsh water environments, and can stably produce high-quality fresh water, becoming a reliable choice for high-standard water treatment projects.
2. Application Scenarios
SWC6 is widely used in fields requiring high-standard desalination and boron removal, with clear and targeted application scenarios. In seawater desalination projects, it is suitable for large-scale coastal desalination plants and island desalination equipment, providing safe drinking water for residents and solving the problem of fresh water shortage. In industrial production, it is applied to power plant boiler feedwater treatment, effectively removing salt and boron to avoid boiler scaling and corrosion, ensuring safe operation of equipment; it is also used in high-salt wastewater recycling in chemical, petrochemical and other industries, and concentration and recovery of high-value substances in food and pharmaceutical fields. In addition, it can be used in emergency water supply scenarios such as maritime rescue and coastal disaster relief, and high-concentration brackish water treatment in arid areas, showing strong environmental adaptability.
3. Technical Parameters
The technical parameters of SWC6 are designed for high desalination and boron removal, ensuring efficient and stable operation. Core parameters are as follows: membrane material is aromatic polyamide composite membrane, with excellent chemical stability and corrosion resistance; membrane structure is spiral wound, effective membrane area is 40.9m² (440ft²); operating pressure ranges from 5.52MPa to 8.27MPa, adapting to the osmotic pressure characteristics of high-salt water; operating temperature is 5℃ to 45℃, pH adaptation range is 2.0 to 11.0, and cleaning pH can reach 1.0 to 13.0, facilitating daily maintenance; nominal desalination rate is ≥99.8%, minimum desalination rate is ≥99.7%, boron removal rate is ≥91.0%; membrane flux is 40-60 L/(m²·h) under standard conditions; service life is 3-5 years under normal operation and maintenance; maximum inlet SDI15 is 5.0, maximum inlet turbidity is 1.0NTU, ensuring stable operation in complex water quality.
4. Product Advantages
The core advantages of SWC6 are concentrated in high desalination rate and high boron removal rate, which are also its key characteristics distinguishing from ordinary membranes. First, the desalination rate is as high as 99.7%-99.8%, which can effectively reduce the salt content of seawater from 35000mg/L to below 500mg/L, fully meeting drinking and industrial water standards. Second, the boron removal rate reaches ≥91.0%, which can effectively remove boron ions in water, avoiding the harm of excessive boron to human health and industrial production. In addition, SWC6 has strong anti-fouling performance, and the specially modified membrane surface can resist the adsorption of colloids and microorganisms, reducing cleaning frequency to once every 4-6 months; it also has excellent mechanical strength, can withstand high-pressure operation, is not easy to be damaged, and has the advantages of high flux and low energy consumption, balancing efficiency and energy saving.
5. Application Procedures
The application procedure of SWC6 is standardized and easy to operate, divided into six steps. First, conduct strict pretreatment of raw water, including filtration, sedimentation, disinfection and anti-scaling treatment, to remove large particles, colloids and microorganisms, avoiding membrane fouling and damage. Second, install the SWC6 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 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, boron removal rate, membrane flux 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 SWC6 strictly follow international standards (such as ISO 20466:2024) and relevant national standards. Raw materials adopt high-quality aromatic 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, boron removal rate, 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 SWC6 is based on reverse osmosis, optimized for high desalination and boron removal. Under high pressure higher than the osmotic pressure of high-salt water, the semi-permeable membrane of SWC6 selectively allows water molecules to pass through, while intercepting salt ions, boron ions and other impurities. Its ultra-small membrane pore size (0.0001-0.001 microns) can effectively block small-molecule salt ions; the special charge property of the membrane surface repels charged ions through electrostatic action, improving desalination effect. At the same time, the modified membrane surface enhances the selective adsorption and interception of boron ions, achieving high-efficiency boron removal. The whole process is chemical-free, energy-saving and environmentally friendly, which is an efficient deep water purification technology.
8. Future Prospects
With the increasing demand for high-standard water treatment in global industry and life, the market demand for membranes with high desalination and boron removal rates is growing. SWC6, with its core advantages, is in line with the development trend of the water treatment industry. In the future, we will optimize membrane preparation technology, further improve desalination and boron removal rates, reduce energy consumption and cost; develop targeted products according to different water quality and 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 high-standard water treatment and water resource recycling.
9. Conclusion
