Subsamples of 10 and 25 mL of the fixed samples were settled in a sedimentation chamber for 24 h and counted according to the Utermohl technique with an inverted microscope at 200 x and 400 x magnifications (Utermohl, 1958; HELCOM

Since 30% of the TN removal is achievable if the biological treatment process functions normally and operates properly without enhanced nitrogen removal (such as nitrification-denitrification process)  and considering HELCOM
recommendation (Table 1), the effluent concentrations for TN are calculated as 30% reduction of concentration of WWTPs' inflow (Table 2).
Despite the actions undertaken by HELCOM
countries, the overall eutrophication status of the Baltic Sea is still unacceptable (HELCOM
