Added value Development in waves Production Reuse Treatment 1900 1980 2000 2020 2040 6-10-2014
First wave 1900-1980 First priority: health Treatment of municipal and industrial effluents Focus on effluent quality (BOD, SS, N, P) Primary treatment, secondary treatment, tertiary treatment 1960-1970 Surface water discharge legislation 6-10-2014
Anaerobic Process COD CH 4 + CO 2 + BIOMASS CH 4 + CO 2 75 Anaerobic methanogenic biomass Low growth rate Production of reusable methane (green energy) Low sludge production (& biomass is asset rather than waste) Granular biomass 100 20 Effluent 5 5 Anaerobic sludge Anaerobic biomass
Major Challenges of today Reduce carbon footprint (global warming, depletion fossil fuels) Reduce water footprint (water scarcity) Reclaim resources 6
Paques Vision and Mission Revitalizing Resources 7
About Paques Leading in biological wastewater & gas treatment Family owned business, Founded in 1960 Number of employees : 375 Number of Operating Companies : 4 (NL, China, India and Brazil) + Sales offices in US and Canada Worldwide presence through network of 20 partners Innovative biological applications for wastewater and gas > 1800 reference plants worldwide > 60 countries 8
Paques services Research & Development Laboratory services Pilot testing Consultancy and services Process design Basic and detailed engineering Manufacturing Contracting Construction 9
How it started Tower Storage for farms BIOPAQ manure digestion and WindPAQ 10
First granular sludge application Full scale UASB reactor: SK Roermond Papier Installed in 1983 11
BIOPAQ IC (Internal Circulation) 1. Industrial wastewater enters reactor and is mixed with granular anaerobic biomass 2. Organic components converted into methane (biogas) 3. Biogas collected in lower phase separator, generating as gaslift 4. Water is forced upwards in riser 5. Gas leaves reactor in liquid/gas separator 6. Water returns through downer into distribution system 7. Effluent is polished in second, upper compartment 8. Biogas from second compartment is collected 9. Effluent exits the reactor 12
Paques references More than 1,800 reference plants in more than 60 countries in the following industries: Pulp and Paper Beer and Beverages Food Distilleries Chemical industry Metal and Mining Oil and Gas Municipalities 13
Worldwide BIOPAQ Ton COD/d per industry Installed base 22595 ton COD/d 14
