1 Industrial high rated anaerobic waste (water) treatment
Daniël Piet (The Netherlands) 2007

2 Contents Introduction Biothane Group Aerobic vs. Anaerobic
Anaerobic technologies Biothane® UASB Biobed® EGSB Practical example + some references

3 Biothane group Biothane Systems United Kingdom Biothane Systems Russia
China Shanghai Biothane Systems International The Netherlands Biothane Corporation Camden NJ USA Biothane Asia Pacific Indonesia To date: > 475 references in > 30 countries

4 Anaerobic vs. Aerobic

5 COD value vs. effluent charge

6 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

7 Full-scale Anaerobic reactors based on granular sludge technology
BBiobed® EGSB BBiothane® UASB

8 Granular sludge (1-3 mm)

9 Full-scale Biothane UASB

10 Full-scale Biobed EGSB


12 Biobed® MP

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

17 Aerobic vs. Anaerobic
