The LG hollow fiber membrane has an asymmetrical structure in which the size of the pore decreases from the inner to the outer surface of the fiber, which helps the formation of an even and thick membrane, increases permeability and an efficient elimination of turbidity. • On the outer surface, the pore size is evenly 0.1micro meter, enhancing the elimination of floating matters, while a few micro meter of inner surface pore size maximizes permeability. • Uniform 250micro meter thick separation membrane layers are formed, offering strong product stability against external shocks.
LG’s hollow fiber manufacturing process is under thorough quality management utilizing the Six Sigma process across all processes from fiber production to module assembly. The deviation of flux among membrane modules is minimized, providing stability and reducing uneven membrane fouling and flow distribution in actual sites.
