Since its launch in 2007, “Inorganic Membrane Brine Refining and Filtration Technology” has undergone multiple enhancements, and so far, Over 20M tons/yr of China’s caustic soda capacity employs this technology, renowned for its concise process, low investment, little footprint, precise filtration, and durable membranes. It ensures high-grade brine for stable electrolysis plant operations, fostering efficient, stable ionic membrane cell performance.

Nanjing Feit High-tech Co., Ltd. has devised the original “FTM-High Flux”and “FTM-Concentration High Extraction”brine refining technologies, grounded in solving enterprise challenges, cost reduction, efficiency gains, low-carbon development, and mutual benefit. These advancements has effectively and completely solved the big problems of the original “Inorganic Membrane Brine Refining and Filtration Technology”, which requires circulating pumps to provide large flow rate of brine circulation, low solid content of the concentrated liquid discharged from the refining and filtration technology system, and large discharge flow rate.
