Air

In this paper, hydrogel membrane techniques used for CO2 removal from air were introduced. Firstly, the PVDF hollow fibers were prepared by dry-jet wet-spinning phase-inversion process, then membrane module was made of them as a CO2 removal equipment. PVDF hollow fiber membranes modified by alkali,

The humidification–dehumidification process (HD) is an interesting technique adapted for water desalination when the demand is decentralized. This technique presents several advantages such as flexibility in capacity, moderate installation and operating costs, simplicity, possibility of using low te
