Impurities reduction in the relevant technological compartments is as follows:

• At the bar rack – 20% reduction of the coarse materials;
• In the anoxic compartment – 20 % reduction of BOD5 and 85 % reduction of nitrogen (anaerobic reduction of the nitrates, transferred there from the aerobic compartment);
• In the aerobic compartment – 95 % reduction of BOD5, 95 % reduction of ammonia, 75 % reduction of phosphorus (by chemical precipitation) if required and suspended solids reduction down to 15 mg/l;
• In the disinfection chamber – 99,9 % reduction of the bacterial impurity (in respect to Esherihia Coli).
