  • Patent number: 5489380
    Abstract: A process for the biological purification of sewage is specified, with which sewage (AW), containing dissolved pollutants, and air (LT) are fed together to a reactor (1) via at least two mutually separate nozzles (3,4). To achieve a high substance exchange in the reactor (1), the streams of the two-substance mixture emanating from the nozzles (3,4) are conducted such that they make impact with each other in the said reactor in an impact zone (PZ). The sewage (AW) is passed from the reactor (1) into Pa settling tank (8), in which bio sludge settles.
    Type: Grant
