摘要:

介绍了采用PX能量回收装置的膜法海水反渗透系统的典型工艺流程,重点讨论了此系统低压提升泵的设计应用及注意事项,并探讨无低压提升泵的海水反渗透系统的运行要求,为系统设计提供参考。

关键词: 海水淡化, 反渗透, 低压提升泵, PX能量回收装置

Abstract:

The typical process flow of reverse osmosis membrane method desalination system with PX energy recovery device was introduced. The design, application and precautions of low-pressure lifting pump in this system were discussed emphatically. In addition, the operation requirements of reverse osmosis desalination system without low-pressure lifting pump are also discussed for reference.

Key words: desalination, reverse osmosis, low-pressure lifting pump, PX energy recovery device
