Characteristics
Benefits
- Compact water treatment plant.
- Easy installation and maintenance.
Areas of application
- Extended aeration domestic wastewater treatment plant with denitrification step
Manufactured in GRP.
- With a pitch of 10 mm
- Roughing (Recommended)
Anoxic reactor
- Removal of organic matter and nutrients.
Biological reactor
- Removal of organic matter and nutrients.
- Turbine air supply
- Fine bubble air diffusers between 1-3 mm.
Decanter
- Sludge recirculation by pumping
- Sludge recirculation: part to anoxic reactor and part to aerobic reactor
Effluent qualities
- BOD5 (%) = 94
- COD (%) = 79
- SS (%) = 96
- NT (%) = 75
- The equipment is designed to treat waste water with the following composition: BOD5: 400ppm, COD: 600ppm, SS: 450ppm, NT: 50ppm
Stages of operation:
- 1- Screen (recommended): Coarse solids carried by the water are intercepted by a grate at the inlet of the equipment.
- 2- The oxygen in the recirculated nitrates decomposes the organic matter and produces nitrogen gas. The agitator facilitates the release of the gas and the mixing of nitrates with the wastewater.
- 3- Biological reactor: In the aerobic reactor, the biological decomposition of organic matter takes place thanks to the supply of air and the generation of aerobic microorganisms.
- 4- 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 .
