The sewage tank membrane structure is commonly referred to as the sealed cover installed over sewage tanks, as it utilizes advanced membrane structure technology. Based on different classification methods, sewage tank membrane structures can be divided into various types: steel-supported reverse-hanging membranes, cable-suspended reverse-hanging membranes, and frameless sealed gas-collecting covers. These are respectively supported by steel structures, suspension cables, and air pressure. Among these, the steel-supported reverse-hanging membrane has the widest range of applications.

Characteristics of sewage tank membrane structures: excellent corrosion resistance, high landscape value, fast construction and installation speed, good fire resistance, a wide variety of installation shapes, low cost, and more.
