Recently, Henan Xinxiang Lifelte Filter Co., LTD. (hereinafter referred to as "Lifelte") independently developed Double linked microporous precision filter in the field of biochemical water treatment has made a major breakthrough, providing a new technical solution for pharmaceutical, medical, biochemical and other high standard water treatment industries. With its unique double-hole structure design and micron-level filtration accuracy, the product successfully solved the efficiency bottleneck of traditional filters in biochemical water treatment, marking China's precision filtration technology to the international leading level.
The two-hole microlinkage structure breaks the filtration efficiency barrier Lifeldt two-hole microlinkage precision filter adopts the "two-hole parallel microlinkage filtration" technology to achieve hydrodynamic optimization through the staggered micron-scale two-hole matrix. Compared with conventional single-hole filters, this technology increases the filtration area by 40% and the flux by 30%, while effectively reducing fluid resistance and reducing energy consumption. Its core filter material is imported modified PVDF membrane, the filtration accuracy can reach 0.1 micron, the retention rate of microorganisms, colloids, suspended particles is as high as 99.9%, to ensure that the treated water quality meets the "Biopharmaceutical industry wastewater discharge standard" (GB 219072020) and the EU EN 12460 standard. "The design of the two-hole microlink is inspired by honeycomb biomechanics, and by simulating the fluid channel pattern of the honeycomb, we achieve efficient collaboration of the filter units." "The two-hole channels of each filter unit can operate independently or be switched together. When the pressure rises due to the accumulation of impurities in one channel, the system automatically activates the standby channel to ensure the continuous and stable operation of the equipment and greatly prolong the maintenance period," said Zhang Gong, technical director of Liffert.
In the wastewater treatment project of a biopharmaceutical enterprise in Henan province, Lifeldt double-hole micro-linked precision filter successfully replaced imported equipment, achieving a leap-forward improvement in treatment efficiency. The daily processing capacity of the project is 500 cubic meters, and the traditional ceramic membrane filter was originally used. Due to the problem of microbial blockage, it needs to be shut down and cleaned three times a month, and the single maintenance cost is 20,000 yuan. After replacing the double-hole micro-filter, the operation cycle of the equipment is extended to 6 months, the maintenance cost is reduced by 60%, and the effluent COD (chemical oxygen demand) index is reduced from 120mg/L to 35mg/L, reaching the direct emission standard. "Liffert's products not only solve our cost pain points, but also give us a significant advantage in environmental compliance." Manager Wang, head of environmental protection of the company, said, "The automatic filter switching function greatly reduces the frequency of manual intervention, and the intelligent monitoring system can also warn the status of the filter material in real time, providing a reliable guarantee for the continuity of the production line."
Market response: Technological innovation-driven industry upgrading Since the double-hole micro-linked precision filter was put into the market in May 2023, it has served more than 30 biochemical water treatment enterprises, covering multiple segments such as pharmaceutical, medical, food fermentation, and genetic engineering. Customer feedback data shows that the average service life of the equipment is 5 years, which is 2 years longer than that of similar products, and the comprehensive cost is reduced by 25%. Li Feng, general manager of Lifelt, pointed out at the industry forum: "The stringent requirements for filtration accuracy and stability of biochemical water treatment have prompted us to break through the physical limits of traditional filtration technology. The double-hole microcoupling technology not only solves the contradiction between "efficient" and "long-term", but also realizes the rapid expansion and customized adaptation of equipment through modular design, providing flexible solutions for biochemical projects of different scales.
At present, Liffert has started the next generation of research and development of double-hole microlink technology, focusing on nanoscale filtration accuracy and intelligent self-cleaning function. The company plans to establish a joint laboratory with a number of universities in China to explore the performance optimization of filter materials in extreme biochemical environments. At the same time, Liffert will increase the layout of overseas markets, and promote China's precision filtration technology to the world through the EU CE certification and North American NSF standards. "Water treatment is the basic guarantee of life science and the core link of green development." Li Feng said, "Lifeldt will continue to be driven by technological innovation, provide more efficient, smarter and more environmentally friendly solutions for the biochemical water treatment industry, and help China's biotechnology industry towards high-quality development."
Today, with the continuous iteration of biochemical water treatment technology, Lifelter double-hole micro-coupled precision filter has redefined the standard of precision filtration with its breakthrough structural design and excellent performance. This innovation not only fills the domestic technology gap, but also provides Chinese wisdom for global biochemical water purification, highlighting the strong reality of China's environmental protection technology enterprises in the field of high-end equipment manufacturing
