- Stage 2 surface area (m²): 60 m²
- Needs:
Two stage reed bed filters fed with raw sewage have become very popular in France for the treatment of waste water in rural areas. However, they have a rather large footprint as far as surface area is concerned. In the case of Escurolles, available surface area was limited, so a more compact solution had to be found
- Solution:
The foot print of the plant was reduced in substituting the second stage reed bed though a recirculating trickling filter for polishing and nitrification.
- Benefits:
The advantage of r treatment of raw sewage and sludge in a French type reed bed could be maintained while making the system more compact
