<p>The invention relates to a method for treating process waste waters highly charged with ammonium in waste water systems, wherein the waste waters are treated with nitrifying microorganisms (nitrifying bacteria) in the presence of a suspended silicated carrier with a specific surface > than 20 m2/g and optionally denitrifying the nitrified waste waters with denitrifying microorganisms (denitrifying bacteria). According to one variation of the method, a fine particle carbon-containing material with a surface pH value of around 6 to 9 is used instead of the silicated carrier.</p> |
