2 Ways Your Facility Can Overcome Water Scarcity

  1. 1. 2 WAYS YOUR FACILITY CAN OVERCOME WATER SCARCITY 4 Next Steps To Get You Started+
  2. 2. Fresh, quality water is a scarce resource.
  3. 3. source: droughtmonitor.unl.edu NO DROUGHT 35% ABNORMALLY DRY TO EXCEPTIONAL DROUGHT 65% of the population live in abnormally dry to exceptional drought areas. 65% POPULATION BY DROUGHT CATEGORY
  4. 4. contained a contaminant from a geologic or manmade source at a level of potential concern for human health source: http://water.usgs.gov/nawqa/pubs/prin_aq/ | 6,600 Wells were sampled for this study 1 5of every groundwater samples
  5. 5. › Reduced surface and groundwater supplies in many areas › Inadequate local supplies and changing regional distribution › Municipalities taking senior water rights from long-standing industries › Plants going idle or shutting down › More regulations driving up production costs (e.g., Clean Water Act Section §316(b), EPA Effluent Limitation Guidelines (ELG) and Air Quality Regulations) What are the Impacts?
  6. 6. “WHEN THE WELL'S DRY, WE KNOW THE WORTH OF WATER.” - Benjamin Franklin
  7. 7. 2 RESPONSE OPTIONS Investigate Alternative Water Supplies 1 Optimize Existing Water Resources 2 2
  8. 8. Investigate Alternative Water Supplies 1
  9. 9. › Municipal wastewater › Other industrial wastewaters › Produced water from oil and gas fields Recycled Water Sources
  10. 10. Thermal Desalination › Steam or hot water used to effectively boil seawater › Commercial Types: Multi-Stage Flash Evaporation and Multiple Effect Distillation Membrane Desalination Technology › Use of semi-permeable membranes (Reverse Osmosis) to produce fresh water › Commercial Types: Sea Water Reverse Osmosis (SWRO), Brackish Water RO (BWRO) Desalination
  11. 11. Optimize Existing Water Resources 2
  12. 12. Wastewater Treatment and Recycle Opportunities › Cooling tower blowdown reuse › Steam generator blowdown and condensate recovery › Softener and filter backwashes › Slurry line flush waters › Storm water › Reverse osmosis reject
  13. 13. Desalination Facility Optimization: Develop A Water Management Plan › Treat and recycle internal process wastewater › Capture and treat storm waters › Minimize water consumption/wastewater production › Prevent contamination of water sources
  14. 14. NEXT STEPS Perform a vulnerability and resiliency assessment Conduct a water audit Perform process integration Determine water reuse or recycling + + + +
  15. 15. Vulnerability & Resiliency Assessment + Key metrics include changes in: • Supply water quality • Supply water availability • Discharge limits • Discharge volume Other assessment metrics to consider: • Sustainability • Sustainable return on investment analysis (SROI)
  16. 16. Water Audit • Perform site familiarization and permit review • Identify water processes and confirm water flow diagram • Evaluate water data and flow measurement to identify water saving opportunities • Conduct sampling/testing +
  17. 17. Process Integration • Perform sources and sinks evaluation for improved process efficiency • Conduct water pinch analysis and process evaluation for improved water-use efficiency reporting +
  18. 18. Water Reuse or Recycling? • Evaluate treatment options leading to process reuse • Perform bench/pilot testing for technology prove out +
