Sewage Treatment Pilot By Nitrification – Denitrification – Dephosphatisation
Teaching Objectives of
Sewage Treatment Pilot By Nitrification – Denitrification – Dephosphatisation
- To understand the degradation phenomena of organic and chemical pollutants by the action of the micro-organisms in an aerobic environment followed by a physico-chemical treatment.
- Operation of a treatment plant according to sampling and daily analyses.
- Characterization of the nitrification – denitrification – dephosphatisation stages.
Technical specifications
- An anoxia tank with stirrer
