Since July 2020, the wastewater of 1,700 students and staff in the new building of Hogeschool Howest in Kortrijk has been treated in a Phytoair® system from Rietland.

This is therefore a demand-driven system: only the water that is effectively reused is purified. Read more about it in this article.
