Preface:

Recently, the highly anticipated “Symposium on the Integration of Nanofiltration Membrane Technology Innovation and Green Industry Development” successfully concluded in Suzhou. The conference was jointly organized by several authoritative environmental protection institutions in China, bringing together experts, scholars, enterprise representatives, and industry elites in the field of water treatment. Together, they explored the latest development trends, innovative applications, and the future of the water treatment industry.

As an important co-organizer of this grand event, Suzhou Proshare not only played an in-depth role in the planning and organization of the conference but also showcased its innovative achievements and practical experience in the field of water treatment during the technical sharing session. Suzhou Proshare’s active participation fully demonstrated the company’s commitment to promoting industry-wide technological exchange and fostering the collective development of the sector.

01 Keynote Report Review

At the conference, experts from renowned domestic universities and industry shared in-depth insights on the development of high-performance and highly resilient nanofiltration membranes, as well as their applications in areas such as ensuring water quality for health, treating industrial wastewater, and material separation.

As a co-organizer of the symposium, Dr. Lin Xiaofeng, Chief Scientist of Suzhou Proshare , presented the “Next-Generation TFN Nanocomposite Thin-Film Special Membrane Material by Proshare” and shared the core development journey of Proshare as China’s first enterprise specializing in TFN membrane technology.

· New Breakthrough in Precision Separation

Nanofiltration membrane technology, as a fundamental and precise separation tool, is deeply integrated into the processes of various green industries.

In his presentation, Dr. Lin Xiaofeng highlighted that Proshare’s self-assembled TFN membranes utilize non-polyamide materials to construct the separation layer, offering advantages in durability. He also shared application cases of Proshare membranes in ultrapure water production, reclaimed water treatment, and acidic wastewater treatment, demonstrating their excellent application performance and prospects.

Based on this technology, the Proshare® NF98 series nanofiltration membrane has been developed. This proprietary multilayer composite membrane, featuring nano-level controlled ultra-thin hydrophilic coating technology, not only provides exceptional anti-fouling capabilities but also achieves a flux up to two times higher than mainstream imported competitors while reducing operating pressure by over 50%. Its comprehensive performance surpasses and can perfectly replace imported alternatives.

· Proshare Membranes’ Journey of Exploration

As the first enterprise in China to develop TFN membrane technology, Dr. Lin Xiaofeng reviewed the company’s development history at the symposium.He introduced how the Proshare team started from fundamental research in materials science and gradually transformed laboratory innovations into practical products.

This process involved multiple critical steps, including membrane structure design, optimization of membrane fabrication processes, and performance testing and validation.

· Technological Innovation and Application Scenarios

The core innovation of Proshare’s TFN technology lies in reducing the thickness of the separation layer to one-fifth that of traditional TFC membranes (approximately 20 nanometers). This breakthrough enables the product to achieve higher flux and lower energy consumption while maintaining excellent separation performance and chemical resistance. According to SGS testing, its key indicators, such as chlorine oxidation resistance and membrane flux, outperform those of mainstream international competitors.

Proshare’s products have been widely applied in critical industrial fields, including petrochemicals, new energy, semiconductors, seawater desalination, and industrial wastewater reclamation. The company primarily serves large central state-owned enterprises and listed companies, successfully entering the supply chains of leading clients in key sectors such as petroleum refining and lithium battery raw materials. With its stable and reliable performance, Proshare has earned a strong market reputation and achieved sustained repeat orders.
