Abstract
The present invention relates to a submerged hollow fiber membrane module that includes a partition membrane having a slanted slit-shaped opening, and thus capable of not only improving operating efficiency of a hollow fiber membrane module by accelerating the water flow, but also allowing easy discharge of highly concentrated raw water around the hollow fiber membrane to the outside of the module during a reverse wash process.
