Selection guide for reverse osmosis membrane for seawater desalination

2026-09-27

Desalination is the core means to solve the shortage of water resources and industrial water in coastal areas. As the core component of the equipment, the selection of seawater desalination reverse osmosis membrane directly determines the efficiency, water quality purity, and equipment operation and maintenance costs. High salinity seawater has strong corrosiveness and complex impurities, requiring extremely high salt resistance, stability, and durability of membrane products. Ordinary membrane products are prone to problems such as decreased desalination rate, flux attenuation, damage and pollution.

In response to the pain points in the seawater desalination industry, Shandong Jinxin Membrane Development Co., Ltd. has developed specialized seawater desalination reverse osmosis membrane products. With the technical accumulation of the doctoral team from Tsinghua University, the membrane fiber structure and preparation process have been optimized, greatly improving the salt resistance and corrosion resistance of the membrane products. The product has been modified through special processes to efficiently intercept harmful substances such as salt, impurities, microorganisms, and heavy metals in seawater. The desalination rate is stable and meets the standard, making it suitable for various large-scale seawater desalination projects.

Jinxin Membrane seawater desalination reverse osmosis membrane breaks through the shortcomings of traditional products, maintaining high-throughput operation under ultra-high salinity conditions, with water treatment efficiency far exceeding industry standards, and lower energy consumption, effectively solving the problem of high energy consumption and low water production efficiency of traditional seawater desalination equipment. The product has extremely strong durability, excellent anti pollution and anti-aging performance, and can operate continuously and stably for a long time, greatly reducing the replacement frequency of membrane modules and the cost of equipment operation and maintenance.

The company has an automated production line with an annual output of 10 million square meters. The quality of seawater desalination membrane products is unified and controllable, and the batch supply capability is strong, which can meet the needs of various projects such as large-scale seawater desalination projects, island water supply, and coastal industrial water purification. With excellent product performance, Jinxin Membrane seawater desalination reverse osmosis membrane has been successfully applied in multiple harsh water treatment projects at home and abroad, becoming the preferred domestic membrane brand in the field of seawater desalination.
