Project summary:

Phosphorus removal from Polish wastewater is essential to improve the Baltic Sea environment. Coagulation is an efficient and robust process to remove phosphates, thus will become more popular in Poland.

The cost of coagulants and the chemical sludge are major drawbacks of the coagulation. The University of Warmia and Mazury in Olsztyn and the Norwegian University of Life Sciences are investigating innovative methods to address these issues to make the coagulation process more cost-efficient. A comparative study on conventional and electrocoagulation, a real-time chemical dosing control system together with novel sensors will be studied in the project.

The world’s mineral phosphate reserves are rapidly depleting and phosphates in wastewater sludge is an important resource. The project will study the methods to increase the plant availability of phosphates in coagulated sludge.

The results are anticipated to be valuable for WWTPs, environmental authorities and research communities.
