An important consideration in the selection of reverse osmosis membranes: environmental friendliness

Release Date:



When choosing reverse osmosis membrane technology, consideration of environmental friendliness is an inevitable requirement for the close integration of modern water resources treatment and environmental protection. With the increasing global awareness of environmental protection and the concept of sustainable development, it has become an important development trend in the water treatment industry to ensure that the whole process of reverse osmosis membrane materials from production to use to waste disposal to reduce the impact on the ecological environment as much as possible.


First of all, when evaluating the environmental friendliness of reverse osmosis membranes, we must first examine the degree of greenness of its production links. The ideal membrane material should be manufactured using a production process with low energy consumption, low emissions and low carbon footprint, avoiding or minimizing the production of harmful chemicals or large amounts of waste during raw material extraction, synthetic processing and finished product manufacturing. In addition, high-quality environmentally friendly reverse osmosis membranes should use renewable resources as a source of raw materials, and pay attention to energy recycling in the production process, in order to meet internationally recognized environmental standards and sustainable development goals.

Secondly, the environmental impact of reverse osmosis membrane in the practical application stage can not be ignored. High-quality environmentally friendly reverse osmosis membranes should have good chemical stability and anti-pollution performance, and will not release harmful components due to contact with different kinds of pollutants in long-term operation. At the same time, for the old film that needs to be replaced or disposed of after the end of its service life, it should be considered whether it is easy to safely degrade or harmless treatment to avoid becoming a new environmental hazard. For example, some membrane materials may produce microplastics or other hard-to-degrade substances after waste due to aging, breakage or excessive contamination, which need to be fully considered and avoided at the beginning of the design.

In addition, the trend of reverse osmosis membrane selection under the concept of circular economy tends to those products with high recycling efficiency. Advanced membrane recycling technology and remanufacturing process enable waste reverse osmosis membranes to be properly treated and effectively recycled, not only reducing the consumption of raw materials required for new membrane production, but also reducing the environmental pressure brought by traditional disposal methods such as landfill or incineration. Through the construction of a complete membrane life cycle management chain, the maximum utilization of resources and the minimization of waste are realized, and the coordinated development of water resources protection and environmental protection industry is further promoted.


In the process of selecting a reverse osmosis membrane, it is important to pay full attention to the environmental impact of its entire life cycle from production, use to disposal. Only by deeply implementing the concept of green environmental protection and actively selecting those reverse osmosis membrane products with small environmental burden and strong recyclability can we meet the needs of high-quality water treatment, effectively fulfill our social responsibilities, and make substantial contributions to the construction of a beautiful China and global ecological environmental protection.
