ABSTRACT:
An apparatus for aerobic biological treatment of waste water is described, in which a great number of carrier members having a large surface area to which microorganisms adhere are movably set in a cylindrical reactor within a given range of height, and the carrier is horizontally moved substantially continuously so that a part of the carrier is cleaned with cleaning air. The partial cleaning system eliminates the disadvantages associated with intermittent cleaning of the whole carrier.
