Modular seabed seawater desalination system

摘要

The present invention relates to a modularized seabed desalination system. The subsea desalination template includes a subsea desalination module section 41 and a modular fluid coupling 46. The freshwater outlet is in fluid communication with the module fluid coupling 46 in the subsea desalination module section. The subsea desalination module 5 with the reverse osmosis cartridge 23 is in fluid connection with the subsea template fluid coupling 47, the seawater inlet section and the concentrated seawater outlet section. The delivery pump assembly 48 for fresh water of the pump module 17 is in fluid connection with the subsea desalination template 1 and the desalination module 5. The seawater circulation pump 49 is fluidly connected to the seawater side of the at least one reverse osmosis cartridge 23. The freshwater pipeline 2 conveys fluid from the freshwater delivery pump assembly 48 to a location above sea level. Furthermore, the present invention relates to a method of exchanging the subsea desalination module 5 and the subsea desalination module 5 in need of service.
