Proshare - Pioneers in Membrane Technology Revolution Team's Groundbreaking Achievements in the Next Generation of Reverse Osmosis Membrane Technology
Proshare Innovation Suzhou Co., Ltd. is a national high-tech enterprise specializing in the R&D and industrialization of third-generation thin-film nanocomposite (TFN) membranes for reverse osmosis (RO), nanofiltration (NF), and material separation applications. Founded in 2017 by a team of overseas-returned doctoral experts led by Dr. Lin Xiaofeng, a recipient of national-level talent programs, the company has emerged as China's sole domestic manufacturer of TFN membranes.
Technological Innovation: Pioneered the application of TFN technology to nanofiltration membranes, achieving fully independent R&D and localized production of both membranes and manufacturing equipment.
Intellectual Property: Holds over 31 patents, with membrane performance reaching internationally leading standards and replacing monopolized foreign products.
Production Capacity: Operates a 2,000 m² R&D facility and a 15,000 m² production base.
Funding: Completed Pre-A Round (2023) and A Round (January 2025) financing, backed by Suzhou Industrial Park Science Innovation Fund and Yong Sheng Capital.
Market Recognition: Designated as a preferred supplier for listed environmental engineering firms and state-owned enterprises.
Leadership:Dr. Lin Xiaofeng, a Ph.D. graduate from the University of Strasbourg (France), has been recognized with provincial and national talent awards (e.g., Suzhou Leading Talent, Jiangsu Dual Innovation Talent) and leads the company's R&D breakthroughs in TFN membrane industrialization.
