ABSTRACT:
A module for a UASB (upflow anaerobic sludge blanket) reactor for anaerobic waste water treatment comprises an overflow threshold for the treated waste water that determines the water level in the module. Several immersed collection domes are provided for the digester gas which are staggered over the entire module cross-section and possess a drain into a collection pipe and an upper evacuation line for the waste air collecting above the water level. All walls, covers and installation parts of the module are made of plastic, if necessary reinforced with steel profiles, and are welded to each other. Also, all drains end at a narrow side of the module where they are connected in a gas-tight manner with discharge ducts which have been installed there along several modules and which may be closed off in sections.
