摘要： A hollow fiber membrane laminate that includes a plurality of hollow fiber membranes wound to form a plurality of layers in a cylinder shape. The hollow fiber membranes are wound around a central axis while reciprocating a feeding point of the hollow fiber membranes along a central axis. Hollow fiber membranes adjacent to each other in each respective layer are separated by a predetermined separation distance. A speed differential z is reduced for successive layers approaching an outer side of the cylinder to maintain the predetermined separation distance. The speed differential z has a value obtained by dividing a pitch of the hollow fiber membranes within a respective layer by a traverse reciprocating distance.

摘要： 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.
