China Petrochemical News Network reported on May 20 that the dual-membrane device for advanced sewage treatment and reuse of Jinling Petrochemical was operating stably.
This device is an energy-saving and environmentally-friendly device.
This year, the installation personnel specifically tackled key problems for this purpose, focusing on the problems of serious concentration polarization of membrane elements in ultrafiltration and reverse osmosis membrane systems, short operating cycles, and long time-consuming routine chemical cleaning.
After the implementation, the effect was obvious, the device was operating stably, and the single operation cycle reached a record of 75 days.
