The efficiency of nitrification has a great influence on the effect of removing nitrogen from wastewater. Problems with the process are associated with reducing the age of activated sludge, lower temperatures of wastewater in aeration chambers, rapid changes in the amount and composition of wastewater containing toxic substances or inhibiting the oxidation of ammonia nitrogen. The research concerned the possibility of cultivation and storage of the nitrifying bacteria biomass, which could be added to the activated sludge in case of a drop of nitrification efficiency. The study showed that even a four-year-old storage of nitrifying bacteria does not result in their complete destruction.
