Anaerobic vs. Aerobic

COD value vs. effluent charge

Anaerobic vs. aerobic Anaerobic Aerobic (classic) Energy consumption Low Biogas production 0,07-0,1 kWh/kg COD 0,03-0,05 kg/kg COD Value High rate Compact design Aerobic (classic) High Air input 0,7-1 kWh/kg COD 0,2-0,6 kg/kg COD Disposal costs Low rate Big footprint Energy consumption Sludge production Surface area

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)

Results* Anaerobic Aerobic Energy consumption 224 kWh/d 2240 kWh/d Sludge production 96 kg/d 640 kg/d (Euro!) (Costs!) Biogas production 1120 Nm3/day - (ca. 340 kJ/s, nett) Chemical dosing lime, nutrients, - * Based on 80% COD removal, general figures

Loading rates (kg COD/m3) Aerobic vs. anaerobic Aerobic: Volume * Activated sludge 0.5 – 1 kgCOD/m3  3200 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

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. 1200 ppm Minimum COD load is approx. 500 - 1000 kg/day
