Hollow fiber forward osmosis membrane

摘要

Provided is a hollow fiber forward osmosis membrane that, when permeating a dilute water such as fresh water into seawater via an osmosis membrane, is able to increase the forward osmotic pressure energy obtained by osmosis and increase generating efficiency in forward osmosis power generation. The relationship between optimal conditions for the inner diameter d and length L of the hollow fiber osmosis membrane to be used in forward osmotic pressure power generation by permeating a dilute water such as fresh water into seawater via the hollow fiber osmosis membrane to increase the flow on the seawater side with said forward osmotic pressure energy and generate electricity with the increased flow, is as in Equation 11 in the range of d = 50 to 200μm, L = 0.5 to 2 m and permeating water volume J = 1.7 x 10
