Problem

Nitrification is an aerobic biological process in which ammonium is oxidized over nitrite to nitrate by two groups of bacteria.  The process only takes place if sufficient nitrifying bacteria are available.  These bacteria are extremely sensitive to temperature fluctuations and inhibitory compounds.  An insufficient amount of nitrifying bacteria leads to exceeding discharge limits.
