Ultrafiltration membrane (UF) has broad application prospects and my country’s industrial structure needs to be optimized

Ultrafiltration membrane (UF) is a microporous filtration membrane with a rated pore size ranging from 1 to 100 nanometers. The pore size is between microfiltration membrane (MF) and nanofiltration membrane (NF). Ultrafiltration membranes are mostly asymmetric membranes, usually composed of three parts: a cortex, a support layer, and a bottom cortex. Ultrafiltration membrane is a polymer semipermeable membrane made of ceramics, metals, polyethersulfone (PES), polyvinylidene fluoride (PVDF), polysulfone, polyvinyl chloride (PVC), etc. The product structure is divided into tubular types , roll type, curtain type, hollow fiber type, etc.

Ultrafiltration membrane is one of the earliest developed membrane materials. It has been widely used in water treatment, environmental engineering, medicine and health, industrial production, seawater reverse osmosis and other fields. Ultrafiltration membrane is an important water treatment technology. Compared with other water treatment technologies, ultrafiltration membrane has the advantages of strong versatility, high separation efficiency, high chemical stability, and simple maintenance. As environmental protection supervision becomes increasingly strict, large-scale The scale of water treatment projects will continue to increase, and the ultrafiltration membrane market has broad development space.

According to the “China Ultrafiltration Membrane Industry Market Analysis Research Report 2023-2027” released by the Industrial Research Center, ultrafiltration membrane applications The field is wide. In recent years, driven by policies, the water treatment industry has developed rapidly, and the ultrafiltration membrane market has expanded rapidly. In 2021, my country’s ultrafiltration membrane market will reach about 9.14 billion yuan. It is expected that from 2023 to 2027, the ultrafiltration membrane market will expand rapidly. The membrane market size will grow at a compound annual growth rate of more than 6.0%.

Ultrafiltration membranes can be divided into two categories: organic membranes and inorganic membranes. Inorganic ultrafiltration membranes mainly include ceramic membranes, metal membranes, etc. Due to the short development time, inorganic ultrafiltration membranes are currently rarely used in the market. In terms of preparation process, ultrafiltration membrane preparation processes include solid particle sintering method, sol-gel method, sintering method, stretching method, track etching method, phase inversion method, etc.

The technical threshold for ultrafiltration membranes is relatively high, and the high-end market is mainly occupied by companies from the United States, Europe and other regions. my country is a major producer of ultrafiltration membranes in the world, but there are few large-scale production companies in the industry, and mainly small and medium-sized enterprises. Due to limitations of technology, research and development and other factors, domestic ultrafiltration membranes are mostly concentrated in the mid- to low-end fields. Specifically, in the international market, the main suppliers of ultrafiltration membranes include Asahi Kasei Industries, Suez Environmental Group, Koch, Evoqua, DuPont, Toray, Mitsubishi and other companies. In China, ultrafiltration membrane manufacturers include Zhejiang Kaichuang, Hainan Lisheng et al.

Industry analysts said that ultrafiltration membranes have excellent performance and a wide range of applications. Under the background of carbon neutrality and carbon peak strategies, The ultrafiltration membrane market has broad development potential. my country is a major producer of ultrafiltration membranes. However, due to technical limitations, domestic ultrafiltration membranes are mostly concentrated in the mid- to low-end fields and do not have competitive advantages in high-end fields. In the future, against the background of demand upgrades, the structure of my country’s ultrafiltration membrane industry needs to be further optimized. .
