Ecodisk® Denit

The biodisks enable to reach high treatment levels on BOD5, COD, Kjeldhal nitrogen and phosphorus. The process being aerobic, there is no denitrification; therefore, it wasn’t possible to have an advanced treatment on total nitrogen. Yet, the discharge standards are becoming more and more restrictive and the total nitrogen
treatment is commonly requested.

The Ecodisk® Denit process uses totally waterproof biological disks that warrant anoxic conditions in order to favor the effluents denitrification. Different possibilities are available: pre-denitrification, post-denitrification or a combined solution.
