膜法海水淡化低压提升泵的设计应用探讨

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

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。

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.
