Discussion on the design and application of low-pressure lifting pump in membrane method desalination system

doi:10.11894/iwt.2020-0034

Abstract

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

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。
