Abstract
To present a membrane element in an immersion type membrane separation apparatus capable of filtering efficiently by holding a uniform filtering capacity on the whole of the membrane surface if clogging occurs in a part of the membrane surface. The membrane element A is composed of a filtration chamber forming part C arrayed by dividing filtration chambers into a plurality in a vertical direction, water collecting transverse groove forming parts B forming transverse grooves (4) for collecting filtered water from each filtration chamber in a lateral direction by connecting with the filtration chamber forming part C, and a water collecting route (10) by connecting with the water collecting transverse groove forming parts B for collecting the water flaker in the lateral direction from each transverse groove (4) and discharging to outside.
