A dialogue through science

Here you can learn about the scientific results gained in our projects as explained by our researchers. Check out the topics and dive into an interesting theme for 10-15 minutes. If you are left wondering, contact us.

The research results have been generated in three projects funded by the Regional Council of South Savo, Finland

Nutrient recovery from municipal waste water by capacitive deionization

Capacitive deionization is based on the movement of ions induced by applying an electric current and it can be used to recover nutrients from an aqueous stream. In this presentation, we explain how different operating parameters and the electrodes influence the separation.

Nutrient recovery from municipal waste water using electrodialysis

Electrodialysis makes use of two techniques: electrochemical and membrane separation. It allows us to recover nutrients from aqueous streams. In this presentation, we explain how different operating parameters influence the separation.

Membrane bioreactor and oxidation for the removal of emerging pollutants

The membrane bioreactor is an advanced water treatment technology. It can be further combined with advanced oxidation techniques to remove emerging pollutants from waste water. In this presentation, we explain how different operating parameters influence the separation of various emerging pollutants from water.

Municipal sludge as a water treatment solution

Large quantities of municipal sludge are generated as a result of municipal waste water treatment. The sludge can be used for fertilizing purposes but it could also be formulated into an adsorbent capable of recovering rare earth metals from aqueous solutions. In this presentation, we explain the use of a sludge-based adsorbent for metal recovery.

Drying of municipal sludge using infrared and microwave irradiation

Municipal sludge contains large quantities of water and the further dewatering of the sludge is quite difficult. In this presentation, we explain our conclusions on dewatering sludge using infrared and microwave irradiation. Additionally, we explain what kind of avenues microwave irradiation opens for the recovery of phosphorous.

Biogas production from ensiled hay

Ensiled hay is a potential raw material for biogas production. In this presentation, we explain more about the biogas potential of ensiled hay and the biogas production based on laboratory experiments.

Pharmaceuticals and the digestion of municipal sludge

Municipal sludge contains multiple pharmaceuticals, whose effect of biogas production is unknown. In this presentation, we explain what pharmaceuticals are present in municipal sludge and what kind of indication on their effect in biogas production can be found in scientific literature.

Raw materials and digestates in biogas production

Biogas can be produced from multiple raw materials, whose composition varies. Equally, the composition of the resulting digestate varies, that can have an effect on the further use of the digestate. In this presentation, we describe the composition of several industrially used raw materials and the digestates generated in biogas production.

Anaerobic membrane bioreactor: biogas production and effluent quality

An anaerobic membrane bioreactor could possibly be used for the production of biogas. In this presentation, we explain more about the operation of such a reactor and our experimental results on various waste waters.
