Abstract
This invention concerns a method for desalination of sea water and a design and construction of a centrifugal filter for desalination of water. The process uses the filter developed based on reverse osmosis technology as a fundamental component that uses hollow fiber membrane modules arranged in a spiral manner around a central support pipe and distributed in concentric rings around the periphery of the rotating section to favor the formation of Dean vortices. Wherein the membrane is built with a structure of an aromatic polyamide as the first layer, followed by a layer of polyestersulfone and a support layer of polyester; applying the material Kevlar 49 in position 1 and 4 on the aromatic chain structure to increase the structure and resistance of the membrane.
