The pollution load to the biofilter is 240 000 PE and the plant capacity is 72 000 m³/d. With the new stage in the treatment process, the amount of nitrogen polluting the Baltic Sea will decrease by 350 tonnes per year. With each euro spent, 87 grams of nitrogen is kept from entering the Baltic Sea each year.
