DEPTH EXPOSED MEMBRANE FOR WATER EXTRACTION

摘要

A DEMWAX~ water treatment system includes membrane modules (102) and a co llection channel (104). The membrane modules (102) are submerged at depth an d tethered to one or more anchors (100) on the ocean floor. A breathing tube (106) extends between the collection channel (104) and a buoy (108) floatin g on the surface of the ocean to expose the collection channel to atmospheri c pressure. A pump (110) pumps the permeate from the collection channel (104 ) to shore through a permeate pipe (112). One or more permeate storage tanks (114) can optionally be disposed within the system, for example, as part of or extending from the collection channel (104), to provide extra storage.
