Transcription

1 aqua consult Ingenieur GmbH Independent Consulting and Planning Engineers for Water, Wastewater, Solid Waste and Environmental Protection Technology Worldwide From the last 35 years of our activity we have more than 1,500 references worldwide aqua consult head office, Hannover Municipal waste water treatment WWTP Halberstadt, 60,000 PE Biogas production 4 MWel from agricultural products Solid waste treatment Mechanical-biological stage

2 aqua consult Ingenieur GmbH Consulting and engineering for Environmental Protection Industrial wastewater Municipal wastewater Solid waste management Sewerage Systems Water supply Biogas-Projects Cost and fee calculation Plant operation Project management Turn-Key-Projects WWTP Wilhelmshaven, PE - pre-denitrification - WWTP Hannover-Gümmerwald Nitrogen and phosphat removal, 800,000 PE Research projects for optimization Inlet structure of Final Clarifiers

3 aqua consult Ingenieur GmbH References in the field of municipal sewage treatment plants from more than 300 projects worldwide Experiences with the design and operation with many different technologies: - biological nitrogen phosphorus removal - aerobic/ anaerobic technologies - optimisation, also by using simulation models - co-fermentation/ biogas projects - sludge water treatment, desintegration aqua consult is represented in the main German expert groups for the preparation of guidelines. Training for designer, operators, authorities (e.g. training for governmental appointed engineers from River States) WWTP Hannover-Gümmerwald, PE - predenitrification and biological phosphorous removal - WWTP Colakli/ Turkey, PE aqua-compact-system WWTP Athens Nitrification reactor, depth 9,50 m

4 aqua consult Ingenieur GmbH Over 700 references in the field of industrial wastewater treatment tanneries dairies and cheese olive products slaughterhouses potatoe sweets fruitdrinks vegetable/ canning chemical industry paper wood rubber industrie oil and coal textile and many other branches High-loaded paper factory waste water, biofilm system, Plattling/Germany Flotation for pre-treatment, Rheda-Wiedenbrück, Germany Wastewater treatment fruit juice industry, Becker`s Eisleben/ Germany Mixing- and equalization tank for Jam production, Göbber/ Germany

5 aqua consult Ingenieur GmbH Biogas technology for municipal and industrial wastewater, sludges, residues and for solid waste Biogas production has the following advantages: - Usage of the energy of the residues - small space required - economic and efficient technologies Anaerobic high loaded reactor - fruit juice production - Anaerobic reactors (2 x 4,000 m 3 ) Anaerobic Treatment of brewery wastewater (UASB), inner-city Anaerobic Treatment of solid waste residues, Wiefels/ Germany

6 aqua consult Ingenieur GmbH Over 250 references in the field of solid waste treatment and management Feasibility-Studies Solid waste management concepts Pre-planning, planning supervision of erection, start-up support Optimization of treatment plants Turn-key projects solid waste collecting and transport mechanical-biological treatment anaerobic treatment biogas production/ used for electricity generation, cooking, CNG production of refined compost and fertilizers landfill technologies leachate treatment Solid waste treatment center Hannover, Sorting, biogas, compost, incineration, landfill. Capacity 2,5 Mio PE Lechate Treatment, Herford/ Germany Solid waste sorting plant, Vorketzin/ Germany Mechanical-biological solid waste treatment, Ennigerloh/ Germany, t/a

11 Pilot Plant Reactors 4 x 80 l Volume

12 Aerobic 2-stage Wastewater treatment Anaerobic treatment of the sludge

13 Sludgedrying Anaerobic sludge Digestion + primary sludge storgae + thermal hydrolysis + Co-Fermentation = energetic autark operation

14 Thermal Hydrolysis Hydrolyse T = 165 C P = 4 bar + Biogasproduction + Dewaterability - Sludge load

15 Co-fermentation Project Shijiazhuang 5 Mw el (surplus sludge, organic production residue)

16 Co-fermentation Project Shijiazhuang 5 Mw el (surplus sludge, organic production residue) Co-fermentation of the residues from the 7-ACA production (that is a raw material for the production of penecillin) The resiude is biotoxic But if we start the digester with sewage sludge, with a slow increasing dosage of the residue, then the biomass is trained (adaption) and we can treat the residue in the reactor
