13. Example project Flow: 1000 m3/d COD: 4000 ppm  4000 kg COD/d
No specific requirements for discharge
(Bulk COD removal (80%), < effluent charge)
Biological treatment system
Aerobic (activated sludge, MBBR, MBR, etc.)
Anaerobic (UASB, EGSB, Biobulk or lagoon type)

14. Results* Anaerobic Aerobic Energy consumption 224 kWh/d 2240 kWh/d
Sludge production 96 kg/d kg/d
(Euro!) (Costs!)
Biogas production Nm3/day -
(ca. 340 kJ/s, nett)
Chemical dosing lime, nutrients, -
* Based on 80% COD removal, general figures

15. Loading rates (kg COD/m3) Aerobic vs. anaerobic
Aerobic: Volume *
Activated sludge 0.5 – 1 kgCOD/m3  m3
MBBR 2 – 3 kgCOD/m3  1070 m3
MBR 3 – 4 kgCOD/m3  800 m3
Anaerobic:
Biobulk/Lagoon 3 – 5 kgCOD/m3  640 m3
UASB 8 – 12 kgCOD/m3  270 m3
EGSB 15 – 25 kgCOD/m3  130 m3
* Based on 80% COD removal, general figures

16. Anaerobic limitations
Applicability Anaerobic Technology
Organic components anaerobic biodegradable
Bulk COD removal step
No N and P removal
Minimum required temperature is 25 Degree Celsius
Minimum COD required is approx ppm
Minimum COD load is approx kg/day
