  1. Wastewater Workshop in Nairobi 29-th August till 03-th September 2011 Optimization ofWastewater Disposal Dr.- Ing. Rainer-Werner Abendt Nuremberg Contact: rainer.abendt@gmx.de Rainer Abendt

  2. Energy Schematic Flow Chart Optimization of Wastewater Disposal Minimization of Sources of energy Demand for energy Energy consumption Wastewater Wastewater Sludge / Gas Wastewater Wastewater Sludge / Gas Treatment plants Biomass / Co-Digestion Biomass / Co-Digestion Sewer system Sewer system Waste treatment plants Sludge (Mono / Co) Sludge (Mono / Co) Waste Waste Waste, Biomass Waste, Biomass Rainer Abendt

  3. Energy Chart Optimization of Wastewater Disposal Sources of energy Wastewater Waste River • Sludge incineration • Waste incineration • Digestion of biomass waste • Use the gas of the dump • Use of the wastewater heat • Potential power addition to the WW treatment plants • Anaerobic waste water processing • Energy generation by digestion of the sludge/ gas • Energy generation with biomass Co-digestion • Hydro Electric power • NAWARO Model used to • Calculate data. • Geothermal Power Rainer Abendt

  4. Co-digestion of Waste at WWT plantMode of operation Treatment plant Waste from Optimization of Wastewater Disposel Sludge Biological waste Contaminated materials Preparation Mixer Storage Electricpower Digester Heat Storage Wastwater Dewatering Utilization Rainer Abendt

  5. Examples of Co-Substrates Optimization of Wastewater Disposel Vegetable residue (Biomass) Grease trap material Rainer Abendt

  6. More Examples of Co-Substrate Optimization of Wastewater Disposal Food waste Frying fat Rainer Abendt

  7. Phosphorus removel by sludge Process Using Denitrification ! Water Treatment No dissolved O2! Bacteria take O2 from inside a macromolecule and use to make CH4 and CO2 Nitrogen (gas) Dissolved Carbon particle N-ox PO4 is converted to PO3 and energy is released Rainer Abendt

  8. Treatment 3. Step: 2. Activated Sludge (N) (low loaded) Water Treatment Pressed Air Denitrification Nitrification Recirculation Carbon Substrate Sludge recirculation Gravity Thickeners Secondary Claryfiers Activated Sludge Rainer Abendt

  9. Water Treatment Air Rainer Abendt

  10. Use of the water heat out of the sewer or the treatment plant Uses of Wastewater Include: • Use of the water heat outside the sewer or the treatment plant for heating or conversion to electricity • As an alternative energy source for the treatment plant • In Anaerobic wastewater processing • For agricultural use through irrigation by farmers • Treated water for recycling in industrial processes • Energy generation of sludge digester (Methane gas) • Energy generation of biomass, or organic wastesimilar with the sludge in the digester • Dried Sludge for fertilizing in agriculture • Sludge incineration for heating energy Optimization of Wastewater Disposal Rainer Abendt

  11. Optimization of Wastewater Disposal Thank you for your attention Rainer Abendt
