On December 28, 2025, the Nanjing Membrane Friends Annual Meeting was held in Nanjing, bringing together dozens of entrepreneurs, industry leaders, and academic experts from across the membrane science and techology sector in Nanjing. First initiated in 2019, this annual meeting has now been successfully held six times at the ends of each year.

Nanjing plays as a role of strategic hub for national membrane industry development in China,where hundreds of scientists and doctors are working on membrane filtration technology since 1989. The city has formed a highly concentrated ceramic membrane industry cluster, supported by a full-chain ecosystem covering materials, module manufacturing, system engineering, and industrial deployment, with dedicated membrane technology industrial parks enabling efficient collaboration across the value chain.

A key advantage of Nanjing’s “Membrane Valley” is its integrated industry----academia-research model, where universities, research institutes, and industrial companies work in close coordination. Combined with strong policy support and access to shared research and industrial resources, this environment enables ceramic membrane technologies to progress from research to scalable, reliable, and long-term industrial applications, strengthening Nanjing’s position in the global inorganic membrane landscape.

Based in Nanjing, TANGENT works closely with the Membrane Research Institute, focusing on ceramic membrane R&D and engineering-oriented innovation. Building on a solid scientific research foundation and proven track record of industrial-scale applications, TANGENT is committed to delivering stable, reliable, eco-friendly and long-cycle membrane separation solutions to global clients, facilitating the achievement of carbon neutrality and sustainable development goals.

TANGENT organized a team-building activity in Luoyang, Henan Province, from December 13th to 17th, 2025. During the five-day trip, participants visited famous scenic spots such as the White Horse Temple, Laojun Mountain, and Shaolin Temple, immersing themselves in historical sites and natural landscapes. Through cultural enrichment, we build strength; through laughter and joy, we deepen our friendships.

The 13th China International Chlor-Alkali Conference was successfully held in Xi'an, Shaanxi, from November 12 to 14, bringing together more than 400 leading industry professionals from over 20 countries. As one of the most influential global forums in the chlor-alkali sector, the event focused on cutting-edge trends, green upgrading, and technological breakthroughs, fostering high-level exchanges across the global value chain.
At this year's conference, TANGENT's ceramic membrane technology emerged as a major highlight thanks to its outstanding performance in primary brine purification for caustic soda and chlorine production. With superior separation efficiency, long-term operational stability, and remarkable energy-saving benefits, the solution attracted widespread attention and unanimous praise from participants. It significantly enhances purification processes, efficiently removes Ca+Mg and turbidity, protects electrolyzers, reduces waste discharge, and provides a key technological engine for the industry's move toward sustainability and high efficiency.
The conference further reinforced TANGENT's position as a global innovator in membrane technology and laid a strong foundation for expanding international cooperation.
TANGENT warmly welcomes chlor-alkali enterprises and technical partners worldwide to connect with us and explore collaborative opportunities to jointly drive technological innovation and sustainable industry development.

Aquatech China 2025 ran from Nov 5-7, 2025 at Shanghai. It gathered over 500 global exhibitors, showcasing the full water treatment chain and hosting forums on applications.

Focused on fluid separation innovation, it offers ultrafiltration/microfiltration solutions, with its CRM series widely used in food, petrochemicals, and pharmaceuticals. The exhibition boosted TANGENT’s global recognition; TANGENT will deepen R&D and drive global water treatment development.

Aquatech China 2025 (from Amsterdam’s expo) runs Nov 5-7, 2025, at Shanghai New International Expo Center, aiding Asia-Pacific water tech exchange. TANGENT, a 30-year inorganic membrane leader, offers ceramic membrane solutions for food, petrochemicals, pharma and wastewater, meeting green goals and EU PFAS rules. It will exhibit at Booth E6D46 with engineers for custom solutions, inviting visitors.

The Seminar on Technological Innovation and Industrial Application of High-Performance Separation Membranes was held in Suzhou on September 20, 2025, hosted by Beijing University of Chemical Technology’s New Materials Alumni Association. It brought together membrane sector experts, scholars and executives to discuss cutting-edge tech, applications and industrialization. TANGENT’s CEO Larry gave a speech on ceramic membranes’ chemical industry applications, highlighting their high-temperature/corrosion resistance and separation performance, plus their latest uses in chemical links like catalyst recovery. This showed inorganic membranes’ role in green chemical development. The event boosted TANGENT’s industry cooperation and showcased its strength; TANGENT will further develop ceramic membrane tech to drive the sector and green chemical/environmental progress.

As Europe edges closer to a potential full ban on Polyvinylidene Fluoride (PVDF) membranes due to their association with toxic PFAS chemicals, the industrial wastewater treatment sector is on the cusp of a significant transformation. This article explores how ceramic membranes are emerging as a viable and sustainable alternative, highlighting the regulatory push, the environmental and health concerns surrounding PVDF, and the advantages of ceramic membranes.

Nanjing Tangent Fluid Technology Co., Ltd. (TANGENT), a 32-year experienced inorganic membrane tech leader, showcased its innovative CRM series inorganic ceramic membranes at the 17th WATERTECH CHINA 2025 in Shanghai. Popular at the world’s largest water treatment exhibition, these membranes solve separation/purification in complex fluids, excel in harsh chemical industry conditions, and serve sectors like petrochemicals and pharmaceuticals. The company vows to advance R&D for sustainable fluid solutions.

The 12th International Chlor-Alkali Technology Conference & Exhibition, organized by Euro Chlor, commenced on 13 May in the dynamic city of Barcelona. TANGENT's "Ceramic Membrane for Primary Brine Purification in Caustic Soda Production" technology emerged as a focal point

From April 21st to 24th, the 26th China Environmental Expo opened in Shanghai, with 2,279 enterprises from 22 countries and regions participating. Spanning 200,000 square meters, it focused on multiple environmental areas. TANGENT's CRM ceramic membrane stood out due to its unique features and wide applications. The expo promotes industry development.

Customers paid a visit to Tangent 's factory this week. They toured the facilities and engaged in in-depth discussions with our team around facility and membrane filtration equipments. The conversations delved deep into the applications of ceramic membranes in the industrial field. Both parties are eager to explore more opportunities for collaboration, aiming to leverage membrane technology to contribute to sustainable development. We're excited about the potential partnerships and look forward to jointly creating greater value in the future.
