With the increasingly strict environmental regulations and the improvement of sustainable development requirements, efficient treatment of industrial wastewater has become an important issue that many enterprises must face. Among them, tubular ultrafiltration membrane technology, because of its unique advantages, has shown excellent results in the treatment of various complex components and high concentration of industrial wastewater.

Firstly, chemical wastewater is a kind of typical wastewater widely used in tubular ultrafiltration membrane technology. This kind of wastewater usually contains a lot of organic matter, inorganic salts, heavy metal ions, microorganisms and chemical reaction by-products, etc., its composition is complex and varied, and direct discharge will cause serious damage to the environment. With its microporous structure and efficient retention capacity, tubular ultrafiltration membrane can effectively separate suspended particles, colloids, partially dissolved organic matter and small molecular pollutants in wastewater, significantly reduce the COD (chemical oxygen demand) and ammonia nitrogen content in wastewater, so as to meet or close to the prescribed discharge standards.

Secondly, electroplating wastewater contains toxic and harmful metal ions and complex agents and other difficult to degrade substances, conventional treatment process is difficult to completely remove. The use of tubular ultrafiltration membrane technology, through the selection of appropriate membrane materials and pore size, can accurately intercept these pollutants, while ensuring the passage of water molecules, to achieve the recycling of water resources, and significantly reduce the impact of pollutants on the environment.

In addition, wastewater from the paper industry is rich in lignin, slurry and other organic impurities, and traditional treatment methods are inefficient and unable to fully recover resources. Tubular ultrafiltration membranes also excel in this area, concentrating solids in wastewater and efficiently separating them, thereby increasing resource recovery and contributing to the development of a circular economy.

In summary, tubular ultrafiltration membrane technology is particularly suitable for the treatment of high-concentration, multi-component industrial wastewater produced by industries including but not limited to chemical industry, electroplating and paper making, which not only solves the problems faced by traditional treatment methods, but also greatly improves the economic and environmental benefits of wastewater treatment.
