On September 23, 2025, the "2025 Suzhou Drinking Water New Pollutant Monitoring and Treatment Technology Seminar", hosted by Tsinghua Suzhou Environmental Innovation Research Institute and other organizations, was grandly inaugurated. This seminar was held on a grand scale, gathering nearly 100 authoritative industry experts, leading enterprises, and water management units. Through various forms such as thematic reports, technology exhibitions, and scientific research dialogues, a high-standard and efficient industry exchange platform was built on site. Zhuhai 9TONE Water Service Inc. (hereinafter referred to as "9TONE Water"), as a well-known enterprise in China's water industry, was invited to attend this grand event and share its cutting-edge insights and practical achievements in new pollutant control with industry peers. Mr. Zhang Liangchun, the Chairman of the company, not only delivered a keynote speech as an invited expert but also undertook the important task of presiding over part of the agenda of the main venue.

01 Focus on New Challenges and Jointly Discuss New Strategies for Drinking Water Safety

With social development, emerging pollutants in water have become increasingly complex. Professors Zhang Xiaojian and Chen Chao from Tsinghua University served as the Honorary Chairman and Chairman of the conference to jointly address this challenge. This conference focused on discussing detection methods and treatment processes for new pollutants and odor-causing substances in water environments, such as disinfection by-products (DBPs), per- and polyfluoroalkyl substances (PFASs), pharmaceuticals and personal care products (PPCPs, including antibiotics, etc.), and endocrine-disrupting chemicals (EDCs). Centering on the monitoring and treatment technologies of new pollutants, the conference exchanged cutting-edge progress, discussed practical engineering challenges, and effectively promoted the technological upgrading and innovative practice of the industry.

02 Deliver Thematic Report and Share Cutting-Edge Innovation Achievements

In the highly anticipated keynote speech session of the conference, as the Director of the Guangdong Provincial Engineering Technology Research Center for New Pollutant Control Innovation, Mr. Zhang Liangchun, Chairman of 9TONE Water, delivered a thematic report entitled "Mechanism and Short-Process Technology for In-Situ Degradation of Odor-Causing Substances and New Pollutants in Water". The report comprehensively and accessibly elaborated on 9TONE Water's breakthroughs in the research on the mechanism of efficient degradation of new pollutants, and focused on introducing an efficient and energy-saving new short-process treatment technology. Addressing the pain points such as limited removal efficiency of specific new pollutants, this technology provided an innovative solution, which triggered enthusiastic discussions and high attention from experts and scholars present due to its significant technical advantages and application potential.

Chairman Zhang Liangchun stated: "Faced with increasingly complex water quality challenges, developing efficient and low-carbon short-process technologies is an inevitable trend in the development of the industry. Our research aims to fundamentally understand and solve the problem of removing odor-causing substances and new pollutants, and this research achievement is expected to provide a new path for improving water quality efficiency and upgrading water treatment facilities."

03 Remarkable Technological Achievements and Lively On-Booth Exchanges

After Chairman Zhang's report, 9TONE Water's booth immediately attracted a large number of participants to stop and communicate. The technical team focused on showcasing an integrated solution supported by the core technology mentioned in the report — an innovative short-process technology combining horizontal tube sedimentation separation technology and catalytic ceramic membrane technology.

9TONE Horizontal Tube + Catalytic Ceramic Membrane for Efficient Degradation of Odor-Causing Substances

9TONE Water has developed the "Horizontal Tube Sedimentation Separation Device combined with O₃ and Catalytic Ceramic Membrane Short-Process Technology", which can efficiently remove 2-Methylisoborneol (2-MIB) and Geosmin (GSM), enabling tap water to meet the requirements of the new national standard, enhancing high-quality water supply and empowering a high-quality life.

Through on-site simulation display of process models and professional explanations, the integrated water treatment solution supported by core technologies was intuitively presented. This exhibition relied on the core horizontal tube technology and innovatively integrated catalytic ceramic membrane technology, vividly demonstrating a set of efficient integrated water treatment system solutions, enabling participating guests to have a more comprehensive understanding of 9TONE Water's innovative strength and technical depth.

04 Deepen Industry Exchanges and Empower the Future of Water Utilities

By participating in this conference, 9TONE Water not only demonstrated its solid technological innovation capabilities and solution strength to the industry but also grasped the latest technological trends through in-depth exchanges with top institutions such as Tsinghua Suzhou Environmental Innovation Research Institute and peer experts. 9TONE Water will continue to uphold the spirit of innovation, deepen cooperation with top scientific research institutions such as Tsinghua Suzhou Environmental Innovation Research Institute, continuously transform cutting-edge technologies into practical applications, and make sustained contributions to safeguarding drinking water safety and promoting technological progress in the industry.
