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 Corporation Camden NJ USA Biothane Corporation Camden NJ USA Biothane Systems International International The Netherlands Biothane Systems International International The Netherlands Biothane Systems United Kingdom Biothane Systems United Kingdom Biothane Systems ChinaShanghai ChinaShanghai Biothane Asia PacificIndonesia PacificIndonesia Biothane Systems Russia Russia To date: > 475 references in > 30 countries

4 Anaerobic vs. Aerobic

5 COD value vs. effluent charge

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

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

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* AnaerobicAerobic Energy consumption224 kWh/d2240 kWh/d Sludge production96 kg/d640 kg/d (Euro!)(Costs!) Biogas production1120 Nm3/day- (ca. 340 kJ/s, nett) Chemical dosinglime, 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/m m3 MBBR2 – 3kgCOD/m m3 MBR3 – 4kgCOD/m3 800 m3 Anaerobic: Biobulk/Lagoon3 – 5 kgCOD/m3 640 m3 UASB8 – 12 kgCOD/m3 270 m3 EGSB15 – 25kgCOD/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
