The present invention has the advantage that the cage has a smooth outer surface and is inserted into the bag with an X-bracing structure to provide improved support for the bag compared to the prior art during backwashing pulses, and at the same time, there is no unevenness on the outer surface, so that it is easy to handle when inserted into and removed from the bag. In addition, if the cage wire mesh is weaved with the same mesh with the material of the same wire diameter, it is possible to save the wire mesh material of the X bracing structure of the present invention compared to the conventional Ramen structure weave in horizontal and vertical ten characters, and there is an effect of making it lighter. .
