BOD5 (mg/l) <10
- COD (mg/l) <50
- SS (mg/l) <10
- Effluent qualities
Effluent qualities
- BOD5 (%) = 95
- COD (%) = 89
- SS (%) = 96
- The equipment is designed to treat waste water with the following composition: BOD5: 400ppm, COD: 600ppm, SS: 450ppm
Stages of operation:
- 1- Screen (recommended): Coarse solids carried by the water are intercepted by a grate at the inlet of the equipment. For small populations, due to the high variability of the influent, it is recommended to install a decanter upstream.
- 2- Biological oxidation: In the biological reactor, the biological decomposition of organic matter takes place thanks to the supply of air and the generation of aerobic microorganisms.
- 3- Decanting: The sludge resulting from the decomposition of the organic matter is calmed, deposited inside the decanter. The decanted sludge is recirculated back to the reactor by pumping .
