There are many types of hollow fiber ultrafiltration membranes, and foreign brands have strong competitive advantages.

Hollow fiber ultrafiltration membrane is an asymmetric semipermeable membrane made of high molecular polymer as the main raw material. It is the most advanced and mature membrane element. The working principle of the hollow fiber ultrafiltration membrane is to use the pressure difference on both sides of the filter membrane as the driving force to make the raw water pass through the microporous membrane composed of hollow fiber tubes, thereby effectively intercepting bacteria, colloids, suspended solids, microorganisms, etc. in the water, mainly including internal There are two structural forms: pressure type and external pressure type.

Hollow fiber ultrafiltration membranes are made of various materials, including polysulfone (PS), polyethersulfone (PES), polyethylene (PE), polypropylene (PP), polyvinylidene fluoride (PVDF), and polyvinyl chloride (PVC). Among them, hollow fiber ultrafiltration membranes made of polyvinylidene fluoride (PVDF), polyethersulfone (PES), and polypropylene (PP) are more common.

The upstream of the hollow fiber ultrafiltration membrane industry chain is the supply of high-performance composite materials such as polysulfones, polyesters, and polyolefins; the midstream is the production and production of different types of products; due to its small size, large water flux, and good filtration effect With other advantages, its downstream is widely used in sewage purification and water treatment in municipal, food, petrochemical, electric power, biopharmaceutical and other fields.

According to the “In-depth Market Research and Investment Analysis Report on the Hollow Fiber Ultrafiltration Membrane Industry in 2023” released by the Industrial Research Center, with the With the continuous development of social economy and the intensification of environmental pollution, problems such as water pollution and soil pollution have seriously endangered the country’s economic development and the safety and health of the people. In addition, the country’s emphasis on environmental protection continues to increase. Hollow fiber ultrafiltration membranes are an effective way to treat water pollution. In this way, demand will continue to grow and the market size will continue to expand. It is expected that the demand for hollow fiber ultrafiltration membranes in my country will exceed 139 million square meters in 2029, and the market size will exceed 7.7 billion yuan.

There are currently a large number of hollow fiber ultrafiltration membrane manufacturers on the market, and competition in the industry is fierce. Foreign brands have strong competitive advantages in production technology, innovation capabilities, brand influence, etc., and occupy the majority of the market share in the high-end market. There are a large number of domestic hollow fiber ultrafiltration membrane manufacturers, but most of them are small and medium-sized enterprises. The industry concentration is not high, capital investment is insufficient, independent innovation capabilities and R&D capabilities are weak, and they are mainly concentrated in the middle and low-end markets.

Currently, foreign hollow fiber ultrafiltration membrane manufacturers on the market include Suez Environmental Group, Mitsubishi Rayon Co., Ltd., Koch Industries, Siemens AG, Toyobo Co., Ltd., etc. Domestic manufacturers include Ningbo Qingshuifang Environmental Protection Technology Co., Ltd., Shandong Zhaojin Film Sky Co., Ltd., Weifang Jinwei Membrane Material Technology Co., Ltd., Beijing Bishuiyuan Technology Co., Ltd., etc.

Industry analysts said that the country attaches great importance to the development of green manufacturing projects. “Made in China 2025” issued by the State Council proposes to organize and implement special technological transformations such as energy efficiency improvement, cleaner production, water conservation and pollution control, and recycling in traditional manufacturing industries, implement plans to improve clean production levels in key regions, river basins, and industries, and solidly promote atmospheric pollution. , water and soil pollution source prevention and control special projects. As an effective means of water pollution treatment, hollow fiber ultrafiltration membrane has good development prospects.
