A mesh variable-typed scale filtering device is provided to improve installation space problems of a separate facility, and to prevent increase of using cost of a separate backwashing pump. A mesh variable-typed scale filtering device includes a cylindrical filter housing(10), a filtering part, a driving part(30), and a control part(60). The filter housing has an upper side in which a wastewater inlet is formed. The filtering part includes an inner filter(24) and an outer filter(22). The inner filter having an opened side is combined on an inner upper side of a filtering housing. A mesh(22a,24a) is formed on an outer circumference of the inner filter at a constant interval. The outer filter has the opened side to be combined with the inner filter. The outer filter has the mesh which is the same with the mesh of the inner filter. The driving part is combined on one side of the outer filter to be moved separately. The control part controls size of the mesh by operating the driving part.
