Driven by market segments, the output value of the separation membrane industry is expected to continue to increase

The separation membrane is a membrane material with selective permeability. According to different material properties, separation membranes can be divided into polymer membranes, metal membranes, and inorganic membranes; according to different application scopes, separation membranes can be divided into microfiltration membranes, ultrafiltration membranes, nanofiltration membranes, reverse osmosis membranes, and pervaporation membranes. Ion exchange membrane, etc. The separation membrane can realize material separation while maintaining the original biological system environment. It has the advantages of high separation efficiency, simple process, convenient operation, and low energy consumption. It is widely used in industry, food, beverage, medicine, energy, sewage treatment and other fields. widely.

Wastewater treatment is currently the largest application market for separation membranes. Against the background of continuous development in the fields of municipal sewage treatment, industrial wastewater treatment, recycled water recycling and other fields, the market demand for separation membranes continues to increase, which in turn drives the continuous expansion of its output value. According to data from the China Membrane Industry Association, the total output value of my country’s separation membrane industry in 2020 was 254 billion yuan.

Reverse osmosis membranes and nanofiltration membranes are currently the mainstream products in the domestic separation membrane market, accounting for a total of 52% of the domestic market share; followed by ultrafiltration membranes, microfiltration membranes and electrodialysis membranes, accounting for a total of 30%; the remaining 20% ​​market share Occupied by gas separation membranes, inorganic ceramic membranes, breathable membranes and other types.

In recent years, against the background of the continuous development of domestic chemical industry, machinery, electronics and other fields, industrial wastewater discharge has continued to increase. In 2021, my country’s industrial wastewater discharge will be close to 76 billion tons. As an important component of industrial wastewater treatment, reverse osmosis membranes will have market demand that will continue to expand in the future as industrial wastewater discharge continues to increase. At present, the domestic reverse osmosis membrane market is still dominated by foreign companies such as Dow Chemical, Hydra Energy, Nitto Denko, and Toray. In the future, domestic companies will need to continuously improve their technology research and development capabilities and accelerate the pace of domestic substitution.

At present, under the background of the rapid development of the domestic new energy industry, the market demand for lithium carbonate is increasing. Metal lithium and its compounds mainly exist in salt lake brine. Lithium extraction technologies from salt lakes in my country mainly include adsorption methods, calcination methods, membrane separation methods, and solvent extraction methods. Among them, membrane separation methods have high efficiency, low energy consumption, and simple operation, and are currently the main method for lithium extraction from salt lakes. Nanofiltration membrane can efficiently separate magnesium lithium ions and is the main carrier of salt lake lithium membrane separation technology. In recent years, its market demand has been increasing. According to the released “2022 Separation Membrane Material Industry In-depth Market Research and Investment Analysis Report” shows that in the future, reverse osmosis membranes and sodium Driven by the two major market segments of filter membranes, it is expected that the total output value of domestic separation membranes will be close to 400 billion yuan in 2023, and the industry has broad development prospects.

Industrial analysts said that in recent years, against the backdrop of increasing domestic industrial wastewater discharge and the rapid development of the new energy industry, reverse osmosis The market demand for membranes and nanofiltration membranes continues to increase, which in turn drives the domestic separation membrane production value to continue to expand, and the industry has good development prospects. In the future, as domestic environmental protection efforts continue to increase and cleaner production rapidly advances, the application fields of separation membranes will continue to expand, the market scale will continue to expand, and the industry has broad prospects for development.
