generally, in the final stage of water purification in sewage treatment process, reverse osmosis (RO) membrane is required before ultrafiltration (UF) membrane filters out small particles. In the reverse osmosis process, water is pushed through the precision membrane under high pressure to separate water molecules from residual pollutants. These pollutants are very small, 1000 times smaller than the width of human hair, such as salt, heavy metals and toxic chemicals such as benzene. This high water pressure, usually more than 10bar, means a lot of energy consumption

the patented technology of Nanyang Technological University, nano filtration hollow fiber membrane, can be applied in ultrafiltration and reverse osmosis, which can combine the two processes. It only needs 2bar water pressure (which is equivalent to the pressure of a domestic pressure cooker) to filter out the same type of pollutants. The water it produces is almost as pure as the water through the reverse osmosis process

Nanyang Institute of environment and water resources of Nanyang Technological University in Singapore has spent two years to develop this breakthrough technology. At present, this technology is being commercialized by m, a derivative company of Nanyang Technological University. The company has 12 sewage treatment plants in Vietnam and Singapore, and will build a pilot plant in Singapore to manufacture this new membrane

Wang Rong, director of the membrane technology center of Nanyang Institute of environment and water resources and the raw materials will move in the pipeline at the required temperature, led the research team to design a new nano filter membrane. He said that this technology is mature and can enter the commercialization stage

"the current reverse osmosis process is energy intensive and needs to be shut down for maintenance, which is also one of the main challenges facing the sewage treatment industry," Professor Wang explained. "Our new membrane is very easy to manufacture. It only needs to use low-cost chemicals. It is 30 times cheaper than the traditional chemical system while expanding the market and increasing the investment of single vehicles, which makes it suitable for large-scale production."

executive director of Nanyang Institute of environment and water resources Ng Wun Jern, Professor of Nanyang Technological University, said: "With the acceleration of urbanization and the rapid growth of global population, more cities and communities will face unprecedented challenges in meeting the growing demand for clean water and sewage treatment. What the world needs is an innovative technology such as Nanyang Technological University's new nano filtration hollow fiber membrane, which enables us to treat sewage and produce clean water at a low cost. Moreover, this technology also has high reliability and ease of use The benefits of maintenance. "

m company, said that this new membrane filled the current market gap in sewage treatment. He said: "we have seen in the laboratory that when the new nano filter membrane is used to treat industrial wastewater, the quality of clean water produced can be comparable to that of the reverse osmosis process, and only a very low pressure is required, thus reducing the cost. Such an effective and efficient technology has great market potential and can be applied to many M projects, including "Materials, design and processing are so closely interwoven in this area, including the treatment of industrial wastewater."

it is understood that before the technology is put into mass production, M company will carry out practical application and test in its own factory to verify its effectiveness and work efficiency
