The company designs, manufactures, and integrates ceramic membranes, organic membranes, and lithium adsorbent materials, and delivers full EPC membrane separation systems across four application areas: salt lake and brine lithium extraction, industrial fluid separation, water treatment and resource recovery, and industrial waste acid recycling. Its technology portfolio includes alumina, silicon carbide, titania, and zirconia ceramic membranes; spiral-wound RO/NF/UF, hollow fiber, and PVDF tubular organic membranes; and aluminum-based and titanium-based lithium adsorbents, with the fourth-generation adsorbent launched in 2024. The company operates a smart manufacturing facility in Nanjing Pukou recognized as a Jiangsu Province Intelligent Manufacturing Demonstration Workshop, plus a wholly-owned Tibet Jiuwu subsidiary in Golmud with 6,000 tons/year of lithium adsorbent capacity.

Jiuwu sells to enterprise and government customers through direct field sales, project-based competitive bidding, strategic partnerships with engineering contractors (e.g., CAMC for Bolivia), and selective BOT operating models. Revenue streams span one-time membrane materials sales, EPC/turnkey membrane integration projects (the dominant 2023 stream at 757 million RMB), BOT/operations services, and technical/after-sales support. Notable customers include Qinghai Salt Lake Industry, Zijin Mining, SDIC Lop Nur, Shengxin Lithium, Jinhai Lithium, Tibet Mining, plus long-tenure industrial accounts such as Sanyuan Chlor-Alkali, Coca-Cola, Budweiser, Yunnan Baiyao, and Nine Dragons Paper, with international projects spanning 40+ countries.

The company has accumulated 178+ invention patents and 132+ utility model patents, led the development of national industry standards for ceramic microporous membrane elements and devices, and received four National Science and Technology Progress Awards plus one National Technical Invention Award. It is designated a national 'Specialized, Refined, Distinctive, Innovative' Little Giant Enterprise, a National Manufacturing Single Champion for ceramic filter membrane and complete equipment, and co-leads the National High-Performance Membrane Materials Innovation Center with Nanjing Tech University. R&D intensity has averaged 5-8% of revenue, with 24.83% of headcount in R&D roles, supporting continuous product generations from first-generation ceramic membranes (2000) through fourth-generation lithium adsorbents (2024).

Revenue model

1. Membrane Materials and Components Sales: Sale of ceramic membranes (tubular, plate-type, high-filling column), organic membranes (spiral-wound, hollow fiber, tubular PVDF), and lithium adsorbents (aluminum-based, titanium-based). One-time product sales with recurring replacement demand as membranes require periodic replacement.
2. Membrane Integration Technology Solutions (EPC/turnkey projects): Complete membrane system design, equipment manufacturing, installation, and commissioning services. Projects include brine lithium extraction, industrial wastewater zero-discharge, tap water treatment, and industrial fluid separation. 2023 revenue: 757 million RMB.
3. BOT/Operations Services: Company operates projects on a BOT (Build-Operate-Transfer) model, such as the 2000-ton/year chloride lithium pilot production line project at Bangeguo Cuo salt lake. Also operates Shanghai titanium dioxide waste acid BOT project generating tens of millions in annual resource recovery revenue.
4. Technical Services and After-sales Support: Process design, technical consulting, on-site technical guidance, and after-sales services for membrane systems.
