  1. Integrated Water ManagementAIChE December 2011 Meeting John Barber, Ph.D. Superintendent Waste Disposal Services Dept. Eastman Chemical Company

  2. Water Scarcity • Increasing worldwide • Previously a developing nation issue • Now Spain, Australia, U.K, U.S. • Quantity and quality concerns • Finite resource

  3. World Water Stress

  4. Disappearing Aral Seain Central Asia

  5. Colorado River-from this to that

  6. South Fork Holston River (8/10/2000)

  7. Global Distribution of Water • 97.5% Oceans • 2.5% Fresh Water • 69.5% Glaciers and Permafrost • 30.1% Groundwater • 0.4% Surface and Atmosphere • 77.5% Lakes, Rivers, Wetlands • 12.2% Soil Moisture • 9.5% Atmosphere

  8. “Many of the wars this century were about oil, but those of the next century will be over water.” – Egyptian Ismail Serageldin, senior World Bank official

  9. Is water the new oil?

  10. Water Footprint Concept www.waterfootprint.org

  11. Water Use in the U.S. • 339 billion gallons/day fresh water withdrawn • 2X population growth for past 200 years • Now 10% less than in 1985, though population grew • Conservation? • Harder to come by?

  12. Water Use in the U.S. • 1300 gallon/person/day withdrawn • 40% for irrigation (78% in California) • 3x average of Europe • US Household use = 100 gal/person/day

  13. World Water Cost and Consumption

  14. Water Conservation – the cheapest gallon of water is one that you don’t have to find, treat, and distribute

  15. Electric Power in the U.S. • Thermoelectric and Hydroelectric • Uses more water than any other single purpose • 131 billion gallons/day • 3% consumed

  16. It takes a lot of water to produce energyIt takes a lot of energy to treat water

  17. Water – Energy Nexus

  18. Energy Intensity of Water Sources

  19. “I am convinced that, under present conditions and with the way water is being managed, we will run out of water long before we run out of fuel.” – former CEO of Nestle, Peter Brabeck-Letmathe in The Economist (2008)

  20. Institutional Structures Sustainable Integrated Water Management Science & Technology to Produce Clean Water for Reuse Management of Water in the Natural and Built Environment Adoption of a One Water Paradigm

  21. “Silo” Management of Water

  22. Integrated Water Management • Reduce demand for freshwater • Increase water recycling and reuse • Turn stormwater into a water supply asset • “Fit for Purpose” – match water quality to end user needs • Green Infrastructure – multi-purposeand multi-benefit • No distinct classes of water • Continual cycle

  23. The Water/Energy/Nutrient Nexus of Wastewater

  24. Wastewater Resource Recovery Opportunities

  25. Example Resource Recovery Center Primary Revenue Ultrapure water for industry makeup and aquifer recharge Peak electricity sales to grid Primary Clarifier or Filter Low Energy Membrane for BOD and TSS Removal Sewage Food waste, misc. organics Electricity Methane Electricity Generation Nutrient Removal and Recovery Anaerobic Digester CO2 Secondary Revenue Irrigation water Fuel savings Inorganic fertilizer Final Filter Algae Conversion to Biodiesel

  26. NPDESNational Pollutant DischargeElimination System

  27. Uses for Recycled Water

  28. Fit for Purpose Water Reclaimed water that has received the most appropriate level of treatment for a specific beneficial reuse

  29. Water Reuse in the FoodProducts Industry • Coca-Cola’s goal  zero water footprint for production • Reduce, recycle, replenish • Partnership with New United Resource Recovery Corporation (Spartanburg, SC) • Move toward total recycle of treated water • Product quality, product safety and public health are paramount

  30. Conversion of Recycled Bottles to Food Grade Plastic • High-speed auto sort • Shred and wash PET • Float bath to remove PVC caps and paper labels • Initial rinse • Chemical treatment and 2nd rinse • Auto visual scan to remove non-spec plastic • Final rinse and dry

  31. Demand and Water Quality Needs

  32. Physical-Chemical Water Reclamation

  33. Manhattan 125 Maintenance Garage

  34. Rainwater and Steam Condensate Harvesting System

  35. The SolaireResidential Tower

  36. Rooftop of The Solaire

  37. Wastewater Managementat The Solaire • On-site blackwater treatment system recycles 100% of building’s wastewater for use in cooling towers, toilets and landscape irrigation • Dual plumbing to accommodate graywaterseparation • Water-efficient fixtures and low-flow toilets • Potable water demand reduced 50% by using recycled wastewater

  38. Rainwater Managementat The Solaire • Water retention layer in rooftop landscaping reduces stormwater velocity and volume • Subsurface infiltration basins remove pollutants from rainwater • Runoff collected in 10,000-gallon basement storage tank with sediment basin and treatment system • Water used for irrigating landscaping and operating the cooling tower

  39. Green Infrastructure • Rain gardens and rain barrels • Porous concrete and permeable pavement • Vegetated swales • Green roofs • Water harvesting • Bioretention and infiltration

  40. Green Infrastructure & the Triple Bottom Line

  41. The $42 Million “Waterless Toilet” Challenge from the Bill and Melinda Gates Foundation
