The downstream demand for microfiltration membranes is strong and national policies provide a good development environment for them.

Microfiltration membrane refers to a porous solid continuous medium with a pore size of 0.1-10 μm, highly uniform, and characterized by screening and filtration. It is mainly used to intercept particles, bacteria, pollutants, etc. from the liquid or gas phase, thereby achieving concentration, The purpose of separation and purification. Microfiltration membranes can be roughly divided into organic polymer membranes and inorganic membranes according to different materials. Organic polymer membranes can be divided into natural polymer membranes and synthetic polymers. Inorganic membranes mainly include metal membranes and ceramic membranes.

The upstream of the microfiltration membrane industry chain supplies raw materials such as polyamide, polycarbonate, cellulose acetate, ceramics, and metals. Representative companies include Northern Chemical Industry Co., Ltd., Guochu Technology (Xiamen) Co., Ltd., and Exxon Mobil Corporation. , Wanhua Chemical Group Co., Ltd., etc., with a large number of related companies and sufficient supply of raw materials; the midstream is the production of different types of microfiltration membranes; the downstream is widely used in food processing, pharmaceutical sterilization, sewage treatment, seawater desalination, and biological preparations and other fields.

According to the “Microfiltration Membrane Industry In-depth Market Research and Investment Strategy Suggestions Report 2023-2027” released by the Industrial Research Center, from In terms of membrane technology application fields, industrial water treatment accounts for more than 30% of membrane technology applications, ranking first, followed by the energy industry and industrial wastewater treatment, both accounting for about 20%. In recent years, with the gradual recovery of the national economy, the level of industrial development has continued to improve, the demand for industrial water has continued to grow, and the aging process in our country has continued to accelerate. The demand for medicine and biological agents has continued to grow. The downstream demand for microfiltration membranes has been strong, and the market size has continued to expand. In 2022, my country’s microfiltration membrane market size will exceed 25 billion yuan.

Membrane technology is an important technical means for sewage treatment and an important component of environmental protection. It is also a high-tech strategic industry in my country. In recent years, the country has continuously increased its emphasis on environmental protection, and has introduced a number of policies to promote the construction of sewage treatment, seawater desalination and other projects, providing a good development environment for the membrane industry. In January 2022, the National Development and Reform Commission and other departments issued the “Guidance on Accelerating the Construction of Urban Environmental Infrastructure”, proposing to increase sewage treatment capacity by 20 million cubic meters per day by 2025, and to add and transform sewage collection pipe networks. 80,000 kilometers, with a newly built, renovated and expanded reclaimed water production capacity of no less than 15 million cubic meters per day. In April 2022, the Ministry of Ecology and Environment released the “14th Five-Year Plan for Environmental Protection Action Plan for the Improvement of Black and Odorous Water Bodies in Cities”, proposing that by 2025, we will promote the basic long-term control and long-term cleanup of black and odorous water bodies in urban built-up areas at the prefecture level and above; at the county level; Black and odorous water bodies in urban built-up areas have been basically eliminated. As one of the effective means of sewage treatment, microfiltration membrane has good development prospects.

Industry analysts said that the foreign microfiltration membrane industry started earlier and has relatively high technical level, research and development capabilities, and production scale. Strong competitive advantage, occupying the main high-end market. The domestic microfiltration membrane industry started late. After a period of development, the gap between it and the international advanced level has gradually narrowed, but there is still room for technology upgrades. At present, domestic microfiltration membrane manufacturers include Hangzhou Kaifiltration Membrane Technology Co., Ltd., Tianjin Dadong Microfiltration Membrane Technology Co., Ltd., Beijing Beishuiyuan Technology Co., Ltd., Ningbo Changqi Microfiltration Membrane Technology Co., Ltd., etc.
