China Water Net, June 28: Filtration membranes mainly include microfiltration membranes, ultrafiltration membranes, nanofiltration membranes, and reverse osmosis membranes.  Among them, the microfiltration membrane (MF) refers to a filter pore size of 0.1-1 micron.  Between the filter membrane.  The microfiltration membrane can pass through macromolecules and soluble solids, trap bacteria, suspended solids and macromolecular colloids, etc., and can be used in the field of liquid separation and filtration.  Microfiltration membrane is the earliest type developed and applied in filtration membrane products.

According to materials, microfiltration membranes can be divided into two categories: inorganic membranes (such as ceramic membranes, metal membranes, etc.) and organic polymer membranes (such as natural polymer membranes, synthetic polymer membranes, etc.);  Filter membranes can be divided into tubular membranes, roll membranes, flat membranes, hollow membranes and so on.  The microfiltration membrane has high surface porosity, thin membrane thickness, and the medium is not easy to fall off.  When in use, it has the advantages of high filtration accuracy, high separation efficiency, low loss of the filtered medium, no secondary pollution, and high reliability.

Microfiltration membranes can be widely used in the fields of medicine, food, beverages, wine making, chemical industry, biotechnology, water treatment, and environmental protection.

Since the 21st century, countries around the world have paid more and more attention to environmental protection, and the demand for microfiltration membranes in the field of water treatment has continued to increase.  my country’s environmental protection policies are becoming increasingly stringent and residents’ requirements for tap water quality continue to increase.  In this context, my country’s tap water purification, industrial and domestic sewage treatment, landfill leachate treatment and other fields have an increasing demand for microfiltration membranes.  The market space for microfiltration membranes growing.

According to the 2021-2025 Microfiltration Membrane Industry In-Depth Market Research and Investment Strategy Recommendation Report issued by the Xin Sijie Industry Research Center, the market demand for microfiltration membranes in my country is showing a continuous growth trend.  In 2012, the scale of my country's microfiltration membrane market was about 4.2 billion yuan, and it grew to 19.1 billion yuan in 2019, with an average annual compound growth rate of 24.2%, showing a rapid upward trend. My country's microfiltration membrane industry started late.  At this stage, the main production companies include Beijing Bishuiyuan Technology Co., Ltd., Tianjin Motian Membrane Technology Co., Ltd., Ningbo Changqi Microfiltration Membrane Technology Co., Ltd., etc., mainly focusing on the low-end market competition , The overall competitiveness is weak.

Industry analysts in Xinsijie said that microfiltration membranes are one of the main product types of filtration membranes.  In my country, its market share is second only to reverse osmosis membranes, and the market share of ultrafiltration membranes is about 10%.  The demand for microfiltration membranes in the field of water treatment and environmental protection is growing, and the market scale is expected to continue to expand.  However, my country's microfiltration membrane industry is not competitive in the high-end market, and foreign companies are in a dominant position.  In the future, the core competitiveness of my country's microfiltration membrane industry needs to be continuously enhanced.
