    Recently, Cao Yiming's team at Dalian Institute of Chemical Physics of the Chinese Academy of Sciences developed a technology for the removal of high concentrations of ammonia nitrogen from hollow fiber membrane contactors in PTFE. Wastewater treatment capacity of 50 tons / day, water ammonia nitrogen concentration of 2000 to 5000 mg / liter, the design of ammonia nitrogen concentration of 10 mg / liter.
    industrial projects by the Institute and Nanjing Biding New Film Technology Co., Ltd. to provide PTFE membrane components and process design, Panzhihua Biyuan Technology Co., Ltd. is responsible for engineering design and manufacturing and on-site implementation of .
    After 72 hours of on-site operation, the concentration of ammonia nitrogen in the water was stable at 2 to 7 mg/L, meeting the requirements of the National Standard for Pollution Emissions (10 mg/L) and the National Standard for Sewage Discharge Level 1 A (8 mg/L), which is the first successful example of industrial application of PTFE hollow fiber membrane in the field of high ammonia nitrogen wastewater.
    researchers say that due to the excellent hydrophobic and anti-pollution properties of the PTFE membrane material, the process uses cheap lime instead of liquid alkali to regulate pH, significantly reducing operating costs. The system has the advantages of low energy consumption, high efficiency of ammonia nitrogen, long membrane life, compact device and simple operation.
    It is learned that Cao Yiming team in 2012 developed a high-performance PTFE hollow fiber membrane core technology, successfully applied to Petrom corporation's international development and cooperation pilot project of natural gas de-CO2, this time in the high ammonia nitrogen wastewater treatment successfully implemented, is PTFE hollow fiber membrane contactor technology in the field of application another important breakthrough.
