    THE UASB PRINCIPLE

    The UASB reactor is a reactor type that is frequently used in anaerobic water treatment.

    The reactor contains a sludge blanket which consists of anaerobic micro-organisms in the form of pellets. These pellets are an essential characteristic of the UASB principle. The reactor is flowed through from the bottom to the top.

    Biogas which mainly consists of methane and carbon dioxide is produced during the anaerobic degrada-tion. A separation system is installed at the top of the UASB reactor. It separates biogas from treated water. In addition it guarantees that the pellets (biomass) remain in the reactor.
