Technical Support on Danube Nutrients
To derive cost efficient measures it has to be taken into account that emissions are modified via their transport from the area of emission to the area of discharge (denitrification, adsorption). Emissions from waste water treatment plants are mainly in the form of dissolved Phosphate which is immediately highly available for algae production. P-emissions via erosion are mainly in particulate form which is only partly available for algae-production. Particulate P- emissions provide a potential P-source which can be partly mobilised in the case of anaerobic conditions in the waters which are a result of eutrophication.
