1 YOUR FLUSH, OUR ENERGY FULL SCALE DEMONSTRATION OF ENERGY POSITIVE SEWAGE TREATMENT PLANT CONCEPTS TOWARDS MARKET PENETRATION Christian Loderer Kompetenzzentrum Wasser Berlin ggmbh , NEREUS Inspiration day, Saint-Omer Funded by the Horizon 2020 Framework Programme of the European Union Grant agreement No

2 Innovative reuse of water, nutrients and energy recovery in Europe

3 3

4 WWTP + energy consumers 4

5 5

6 WWTPs are the highest energy consumer in a municipality! 6

7 WWTP the Energy consumer 7

8 BUT WWTPs try to improve themselves! 8

9 Energy-positive WWTP a DREAM? Is there a potential by treating your Pooh to become energy-neutral or energy-positive as WWTP? (without using external renewable sources) Are energy-positive WWTPs without external renewable sources still a DREAM? 9

10 We as a consortium say NO it s no dream, energy-positive WWTPs are possible! 10

11 Less aeration 175 kwh/pe*a 4 kwh/m³ (120 g COD/pe*d, 120 L/pe*d, 1000 mg/l COD) 105 kwh/pe*a 2.4 kwh/m³ More biogas 53 kwh/pe*a 1.2 kwh/m³ 42 kwh/pe*a 0.96 kwh/m³ 17 kwh/pe*a Waste heat 17 kwh/pe*a 0.38 kwh/m³ Theoretical energy potential in wastewater organics WWTP: 60% of COD in sewage sludge Digestor: 50% of COD into biogas Methane yield: 320 L CH 4 /kg COD CHP plant: 40% electrical efficiency 11

12 The POWERSTEP Technologies 12

13 The POWERSTEP case studies 13

14 Results within Awareness Concept level Technological level 14

15 Results within POWERSTEP Technological level Stable operation with an enhanced carbon extraction over 2 years Succesful implimention of a advanced nitrogen control 15

16 Results within POWERSTEP Technological level First comparison of a full-scale 1-stage & 2- stage mainstream anammox process under real wastewater conditions New important finding concerning both processes from a operation as well as microbilogy point of view 16

17 Results within POWERSTEP Technological level On-off tests resulting in high transformation rates within short minutes Holistic concept how to use also waste products (e.g.: heat, oxygen and metabolic by-water) in the WWTP 17

18 Results within POWERSTEP Technological level Successful start-up and test of a Heat2Power pilot integrated in a CHP unit Creating an energy model calculating revenues using different valorization scenarios 18

19 Results within POWERSTEP Technological level Nitrogen recovery is possible & it can end up in a successful business model Implementation of nitration & building a decision support tool for SDE treatment technologies 19

20 Results within POWERSTEP Concept level Nowadays energy-neutral & energy-positive WWTPs are possible with state-of the art technologies In the near future energypositive (up to 170%) are possible with advanced technologies Carbon-neutral WWTPs still stay a dream also with advanced technologies 20
