  1. 1. Trinity College Dublin 2016 Rethinking Resource Recovery From Wastewater An Appetizer Arne Backlund Backlund ApS www.backlund.dk www.facebook.com/backlund.aps www.researchgate.net/profile/Arne_Backlund www.linkedin.com/in/arnebacklund
  2. 2. http://www.iwa-network.org/downloads/1440858039- web%20State%20of%20the%20Art%20Compendium%20Report%20on%20Resource%20Recovery %20from%20Water%202105%20.pdf
  3. 3. - RECOVERY OF RESOURCES FROM WATER STATE OF THE ART - INTRODUCTION - DEMAND, REGULATION AND POLICY AND SOCIAL ASPECTS - INNOVATION, ADOPTION AND GOOD EXAMPLES - CONCLUSIONS, FUTURE TRENDS AND THE ROLE OF THE IWA CLUSTER
  4. 4. Ancient Rome versus Ancient China & Japan
  5. 5. Arne Backlund
  6. 6. Present Human Organized Metabolism - Open-Flow System - Premised on Nature as Indefinite - Exhausting its Sources of Nourishment - Without Paying its Bills Could Human Beings in Politics Reorganize Humanity in Nature & Nature in Humanity?
  7. 7. Main Objectives of Sustainable Sanitation •To Reduce Health Risks related to Sanitation,Contaminated Water and Waste •To Prevent Pollution of Surface and Ground Water •To Prevent Degradation of Soil Fertility •To Optimise Closing the Loop of Human Excreted Nutrients, Organic Material and The Water Cycle Considering Energy & CO2 Balances •Economically and Ecologically Sustainable and Culturally Acceptable Systems
  8. 8. Experienced Problems From Rural Area Work In Eastern Germany 1989 - 1993 •High Subsidies Building CWWTP •Very High Subsidies Establishing Sewers - Up To 95 % •Costs - Up to Euro 50000 to Connect one House •”HOAI” 10 % of Total Cost •Mastering the Art of Tendering •PPP ”Betreibermodelle” & ”Kooperationsmodelle” •Not Supporting Innovation & Visions about Ecological & Economical Sustainable Sanitation
  9. 9. My Way - Innovative Production and Waste Reducing Handling Systems in Garnment Industri
  10. 10. Tentative Holistic Reflection •We Can´t Solve Problems by Using More of the Same Kind of Thinking (Paradigm) we Used Creating Them! •Conventional Waste Water Solution – with Mixing & Dilution – Best Solution to Polution? •Why do Human Beings with Two Outlets Design and Use Toilets with Only One Inlet? •When the Solution is Simple, God is Answering!
  11. 11. Flow or Stream of Material •Human urine contributes to about 80 % of the load of N and 50 % of the P load of conventional domestic wastewater •Human Urine treated conventional requires large amounts of energy producing problematic sludge
  12. 12. Flow or Stream of Materials •We Excrete most of the Nutrients we Consume •Human Urine contributes with only 1 % of the Volume of Household Wastewater but contains 80 % of N, 55 % of P and 60 % of K and less than 0.6 % of Cadmium and 0.06 % of Lead
  13. 13. Phosphorus •One Person Excrete 1 KG P/year. •0.7 KG in Urine and 0.3 KG in Faeces. •Human Phosphorus Returned to Soil Would Cover 80 % of P Demand •In Agriculture Short of Phosphorus Human Excreta could be a Golden Opportunity. •In 100 years Phosphorus Could Be Gone.

  17. 17. 1) The first urine product is urine stabilized by nitrification and destillated resulting in amonium nitrate + P + S with a final water content of 4 %. 2) The second urine product is struvite (MgNH4PO4*6H2O), which precipitates when magnesium oxide is added to human urine. Struvite is mainly a phosphorus fertilizer 3) The third urine product is ammonium sulphate, where ammonia is stripped using sulphuric acid Present research condensing human urine-derived nutrients
  18. 18. Value from Urine - project details • Title: Bio-electrochemically-assisted recovery of valuable resources from urine • Project Acronym: ValuefromUrine • Total Cost: 3.85 million € • EC Contribution: 2.91 million € • Duration: 48 months • Start Date: 01-09-2012 • End date: 31-08-2016 • Consortium: 7 partners from 5 countries

  50. 50. Reduced costs using WW & Sludge application to EWSRP •Reduces Demand for Chemical Fertilizers •By far Most Important Public or Private Cost Reduction - Allocating Nutrient Removal to EWSRP •Cost kg N Conventional N-Removal Often 10 Times Higher than kg N price of Chemical Fertilizer •Primary Cost Reduction Potential related to Establishment •Multifunctional Potential related to Cd uptake
  51. 51. Municipality Task Set Up (Question/Demand) 50 % Reduction in N-Outlet to Enköping Stream Using Alternatives To Conventional N-removal on CWWTP. Consultant Answer/Solution •30 t N/y Removed by Fertilizing 80 ha Energy Willow Plantation at Local Farm •20 t N/y Removed by use of Stored & Hyginized Sludge from Septic & Black Water Tanks + Small WWTP on Local Energy Willow Plantations •10 t/N/y Internal Reductions on CWWTP.
  52. 52. Enköping Municipality, Central WW Treatment Plant, Central Heating Plant and Five Farmers •System improving Closing Local Nutrient Loop from WWTP and Single Households to EWSRP •New Thinking (New Paradigm) about Interaction Between Wastewater Handling, Agriculture and Energy Production to Local CHP •Good Co-Operation with Local Farmers Recycling Nutrients from Wastewater Streams to Cultivated Soil •Environmental Advantages •Economical Advantages Distributed Between Municipality, Energy Company and Local Farmers
