ABSTRACT:
There is a disclosed or process for treating industrial waste water highly loaded with ammonium, by treating the waste water with nitrifying microogransims (nitric bacteria) in the presence of a suspended carrier substance with a specific surface area of >20 m2/g and optionally a denitrification with denitrifying microorganisms (denitrifying bacteria). According to a modification of the process, a finely-divided carbon-containing material with a surface-pH value of around 6 to 9 is used instead of the silicate carrier substance.
