4 Advanced Biological Nutrient Recovery (ABNR ) November, 2015

5 5 The Challenge The Challenge: Advance innovative technology through multiple stages of development Validation of techno-economics at a qualified scale Managing expectations of a large number of stakeholders The Approach: Engage stakeholders in a collaborative process of development Work from the problem back Does it work, is it economical and can it scale to meet restricting nutrient regulatory compliance? Long-term solution vs short term fix Continuous improvement Paragraph 3.4, page 74

6 Technology Development Roadmap Research & Develop Company established with the interest to pursue a biological method for phosphorus and nitrogen recovery Prototype and bench scale design demonstrate excellent performance and bolt on capability Contract awarded pulp and paper wastewater treatment pilot study (Inland Empire Paper Company IEPCo) Pilot Gen I Preliminary process patent filed Northwest muni pilot for low level phosphorus recovery (0.05 mg/l TP or less) at Post Falls, ID Performance level exceeds expectations averaging less than mg/l TP Process patent awarded # Demonstration & Gen II Development Gen II Implementation Integration and automation of mechanical and biological processes Technology Optimization Process (TOP) focused on reducing costs and improving efficiency Northeast muni pilot awarded: Upper Blackstone Listed in WEF Technology Roadmap Great Lakes muni pilot awarded: Perrysburg, OH First EPA 319(H) project Integration of outputs from TOP into fully integrated solution Transition from an emerging technology to full production and implementation Validate performance under changing conditions (weather, plant operating cycles, etc.) Demonstrate, Optimize and Commercialize 6

10 Total Phosphorus Total Phosphorus Feed Permeate Total Phosphorus, mg/l IEP PNW Muni Blackstone Perrysburg EPA 319(H) Feed Permeate Consistent phosphorus recovery across size and application 10

11 Next Steps Partner and assist to fund biological and sustainable solution from TDL 2 3 to TDL 3 4 Conduct a fully integrated Gen II demonstration program Integrates process optimizations from the internal TOP process for: Process automation Process enhancements (ie. Lighting, Seasonal Kinetics) Continuous harvest / wasting Gen II Demonstration 12 months program treating 450,000 gallons per month Estimated cost $475,000 LIFT contribution: $350,000 Clearas contribution: $125,000 Low level phosphorus recovery to <0.04 mg/l 11

13 Fertilizer Recovery from Urine and High Strength Waste Streams Harold L. Leverenz, Ph.D., PE University of California at Davis Russel M. Adams, PE Advanced Organic Methods LLC George Tchobanoglous, Ph.D., PE University of California at Davis Webinar with LIFT P-Recovery Focus Group 3 November 2015

14 Topics Significance of urine in wastewater Description of present technology Performance metrics Next steps

15 Chemical Properties of Urine Constituent Concentration, g/l COD 2-10 Nitrogen 7 10 Alkalinity (as CaCO 3 ) Phosphorus Potassium Sulfur Sodium 3-4 Chloride Heavy metals Low Trace constituents High Adapted, in part from: Maurer et al. (2006) Treatment processes for source separated urine. Water Research,

16 User Interface for Source Separation Current concept is a urinal or split bowl toilet Dual flush, micro-flush, dry toilets with urine capture 16

17 Rationale for Separate Management of Urine Enhance the effectiveness of wastewater treatment, meeting permit requirements Potential to recover / recycle nutrient content Reduce amount of energy used for nutrient removal in wastewater treatment Reduced TDS in effluent (reduce energy for RO/potable reuse; meet effluent TDS limits) Control salt accumulation in near zero-discharge water recycle systems Reduced pharmaceuticals and chemicals in the environment Support developing green building movement

18 Ammonium, phosphate, potassium recovery

19 Automated nutrient recovery skid

21 Struvite forms

22 5 to 15 percent N

23 Steam Distillation Performance (preliminary) 23

24 Energy Related to Nitrogen Cycle Energy to fix nitrogen from atmosphere (N fix) 40 to 50 MJ/kg N * Energy to nitrify / denitrify (N lost) 10 to 40 MJ/kg N Energy for sidestream anammox (N lost) 18 MJ/kg N * (limited potential) Energy for steam stripping (N recovered) 50 MJ/kg N (N recovered) * from Mark van Loosdrecht (2014)

25 Application Satellite and Decentralized Local-scale fertilizer production More effective wastewater treatment Isolate problematic constituents 25

26 Vacuum System for Urine Collection 26

27 Current performance metrics Urine > 95 percent ammonium recovery > 98 percent phosphate recovery potassium recovery under investigation Digestate side-streams (esp. thermophilic) 98 percent ammonium recovery Diary wastewater Not yet tested

28 Next steps Addressing commercial inquiries Green buildings, thermophilic digesters Developing business case for nutrient recovery Organic certification of fertilizer Use of fertilizer on farms Continued refinements in energy efficiency Strategies for potassium recovery Characterization of phosphate precipitates, ABC Impacts on wastewater treatment processes Management of process bottoms

34 Discussion and Next Steps Future calls and meetings Use a different platform to allow for open discussion with all participants; WERF looking into AdobeConnect Topic discussion ideas for next call? Please share with Peter, Christine, and Jeff Christine to send out doodle poll to schedule next call for Jan- Feb 2016 Consider having a face-to-face meeting at the WEF/IWA Nutrient Removal and Recovery Conference next Jul 2016 Looking for new vice-chair Thanks to Steve Reusser for serving as Co-Vice-Chair! Good luck on your retirement, Steve! Paul Zimmerman is Co-Vice-Chair Looking for a new 2 nd Co-Vice-Chair. If interested, please contact Peter, Christine and Jeff

35 Discussion and Next Steps (cont) Dewaterability of Bio-P sludge Who is interested in this topic? Expanding the scope of this Focus Group Is N, ammonia recovery something we d like to consider for this group? Airprex pilot studies Is anyone involved in this? Would like to invite those who are working on pilot study to share experience on next conference call. Will also invite Airprex President, Gerhard Forstner, to present on next call. Two technology providers Will send out a survey to see who is interested in learning more of the technologies presented on today s call
