(1) Shape of Element
The membrane element is a flat sheet type as shown in Fig.I-4. At the normal filtration
operation, the sludge accumulated on the membrane surface is cleaned up effectively with
upward water stream generated with the scouring air supplied from the air diffusers installed
at the bottom side (Fig.I-5). This mechanism ensures the stable filtration since the membrane
does not easily admit of sludge adherence to its surface.
In addition, thin membrane element which consists of two membrane sheets and spacers in
between makes it possible to have higher membrane packing density in the module similar to
that of a hollow fiber membrane, and also the vibration of elements by scouring air improves
membrane cleaning efficiency.
