Tertiary treatment - IRIDRA's solutions
For the tertiary treatment, IRIDRA proposes the following technical solutions
Classical constructed wetlands
- Constructed wetlands with horizontal subsurface flow (HF)
- Constructed wetlands with free water surface (FWS)
- Hybrid constructed wetlands (HF + FWS)
Intensified constructed wetlands (Constructed wetlands 2.0)
Integrated additional solutions
