There are many types of tubular membranes, and the wastewater treatment field is its largest demand end.

Tubular membrane refers to a membrane that is cylindrical or cylindrical in appearance and can place the channels of materials and liquids in a pipe with a certain diameter. Compared with other forms of membranes, tubular membranes have the advantages of high filtration accuracy, difficult channel blockage, strong anti-pollution ability, long service life, and recyclability. They are widely used in many fields such as wastewater treatment, pharmaceuticals, and food processing.

There are many types of tubular membranes. According to different filtration precision, tubular membranes can be divided into tubular reverse osmosis membranes, tubular ultrafiltration membranes, tubular nanofiltration membranes and tubular microfiltration membranes, etc.; according to different raw materials, they can be divided into inorganic tubular membranes and organic tubular membranes. There are two types of membranes; according to different pressure drive forms, they can be divided into two types: external pressure tubular membranes and internal pressure tubular membranes. Different types of tubular membranes have different properties. Taking organic tubular membranes as an example, they can be subdivided into polyvinyl chloride tubular membranes, polyolefin tubular membranes, polysulfone tubular membranes and other types. They have many advantages such as corrosion resistance and good machinability. The scope of application is extremely wide.

According to the “2023-2028 China Tubular Membrane Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center, The field of wastewater treatment is the largest demand end for tubular membranes, including oily wastewater treatment, heavy industrial wastewater treatment, textile bleaching and dyeing wastewater treatment, and chemical wastewater treatment. In recent years, as my country’s environmental protection policies have gradually been implemented and taken effect, the prosperity of the wastewater treatment industry has continued to increase. In 2022, the size of my country’s industrial wastewater treatment market will reach 546.18 billion yuan, setting a record high. In this context, tubular membranes are an important consumable for wastewater treatment, and their application demand will become increasingly strong.

At present, due to factors such as high technical barriers and high production costs, the global high-end tubular membrane market is mainly concentrated in European and American countries, and Chinese companies mainly produce mid- to low-end products. Synder Group of the United States, POREX Company of the United States, Dow Chemical Company of the United States, DeuHuB Aeration Equipment Company of Germany, LOCKE of Germany, etc. are world-renowned high-end tubular membrane suppliers. POREX Company of the United States is a representative enterprise of tubular membranes in the world. The sales volume of its POREX tubular membranes ranks among the leaders in my country and even the world.

In terms of the local market, my country’s tubular membrane industry started late and has a small number of market participants. Representative companies include Jin Membrane Technology, Jiarong Technology, Liaogang Co., Ltd., Sanda Membrane, etc. Jinmembrane Technology has core production technologies for ceramic microfiltration membranes and tubular membranes, and its products have been applied in industrial wastewater treatment, urban sewage treatment and other fields.

Industry analysts said that as a thin film subdivision product, tubular membranes have excellent performance and have broad application prospects in the field of wastewater treatment. In the future, as market demand is gradually released, the development speed of my country’s tubular membrane industry will accelerate. At present, due to factors such as high technical barriers, my country’s high-end tubular membranes still rely on imports. It is expected that in the coming period, as local companies continue to exert their efforts, the localization process of my country’s tubular membrane market is expected to accelerate.
