Recently, the high-throughput and high-rejection nanofiltration membrane produced by Yanshan Petrochemical Hi-Tech Co., Ltd.'s 40,000 nanofiltration/reverse osmosis membrane device has passed the authoritative testing and certification of the Tianjin Institute of Seawater Desalination and Comprehensive Utilization of the Ministry of Natural Resources. The product performance Reach the international advanced level.
Nanofiltration membranes are mainly used in water softening, micro-pollution desalination, and industrial pure water manufacturing. With the rapid development of new energy, medicine, environmental protection and other industries, the demand for domestic high-performance nanofiltration membrane products is increasingly urgent in the domestic market. Yanshan Petrochemical High-Tech Co., Ltd. established a joint production, sales and research team to continuously optimize the production process and formula, carry out many experiments and researches, find out key parameters, and produce nanofiltration membrane products with both high water flux and high desalination rate, realizing the first continuous The production area is 7000 square meters.
