Elgin Equipment Group 316b solutions

  1. 1. EEG Water 316(b)
  2. 2. Summary of 316b There are 544 U.S. power plants and several other facilities that will be affected by 316(b). These facilities withdraw at least two million gallons per day of cooling water. The national requirements will be implemented through National Pollutant Discharge Elimination System (NPDES) permits. It requires that existing facilities that withdraw at least 25% of their water from an adjacentwaterbody exclusively for cooling purposes reduce fish impingement.
  3. 3. EPA 316(b) The EPA gives generators seven options for meeting “best technology available (BTA)” requirements for reducing impingement: • Closed cycle cooling • Velocity caps • Modified traveling screens • Seasonally deployed barrier nets
  4. 4. EPA 316(b) Closed Cycle Cooling Modified Traveling Screens Seasonally Deployed Barrier Net Velocity Caps Drum Screens Tee Screens Flat Panel Screens Aquatic Filter Barrier
  5. 5. Cook Legacy 316(b) Scope Product Description Highlights Materials Jacquelyn Coating Permanent metal coating that resists bio-fouling Effective, safe for the environment, permanent solution. Less expensive than temporary coatings or building from other materials. TIG-Welded Wedge Wire Durable, strong, & flat wedge wire Tougher & stronger than resistance weld, better for stringy debris & ice than profile bar Solutions Tee or Drum Screen Cylindrical screens that don’t clog or kill fish New flow modifier is most efficient on the market, and can be scaled for specific site. HemiScreen Half cylinder screen for shallow water Offers good performance, and no moving parts AirBurst System to deliver a controlled burst of air to clean screens Our experience ensures a system that works “out of the box” rather than costly mechanical integration IceBreak System to deliver intermittent air near the intake to prevent icing Integral add-on to the airburst system is more cost effective than stand-alone. Our IceBreak algorithm supports efficient mixing. Debris Jet System to deliver sparge of air to halt debris Bring screens to shallow water Bubble Meter Monitors head loss across a screen Ensures that the screen is free of debris Flow Blade Induces sweeping velocity in stagnant water Supports fish passage in estuarine or intermittent flow environments
  6. 6. Cost Comparison Technology Site-Specific Cost (Million USD) Wedge Wire Screens $3.5-$144 Aquatic Filter Barriers $9-72 Barrier Nets $0.1-$14 Modified Traveling Screens $0.3-$44
  7. 7. EPA 316(b) Meeting impingement standards with Wedgewire screens: 1. Lower design velocity 2. Sensitivity analysis & standard orientations go here.
  8. 8. EPA 316(b) Make it easy to install Traveling screens - fit with civil work Wedgewires - fit in the water body
  9. 9. Traveling Screen Considerations • Velocity & resulting screen quantity • Civil work for screen fit • Civil work for additional bypass • Ongoing operation & maintenance
  10. 10. Wedgewire Screen Considerations • Velocity & resulting screen quantity • Water body • Water quality
  11. 11. Important Details: Flow modification Old Flow Modifier Velocity comparison
  12. 12. Feature Description Ingersoll Rand Air Compressor Reliability of with industry leader RAMA™ Control System and easy-to-use HMI Monitor and control the system in an intuitive manner Icebreak™ System Control ice Bubbler System Monitor head loss AirBurst Systems
  13. 13. Literature Review • Testing has been performed on wedgewire screens for decades • Alden Lab performed study of 0.5 and 1.0mm slot wedgewire screens on behalf of EPRI • Egg and larvae were excluded in most cases considered • The screen performance in estuarine environments was impacted by the maximum slot velocity & the ratio of maximum to slot velocity
  14. 14. Gunderboom MLES MLES™ Aquatic Filter Barrier | Gunderboom Basic System : • Full-water-depth filter curtain comprised of treated polypropylene/polyester fabric • Suspended by floatation billets on the water's surface • Patented systems
  15. 15.

  18. 18. Case Study:Traveling Screen Retrofit Project: Cooling water intake system Problem: Fish concerns & maintenance on traveling screens Solution: New wedgewire screen with low velocity to avoid clogging. AirBurst™ System Installation Payback: 24 months
  19. 19. Case Study: RawWater Intake Project: Raw water supply for a complicated waterway Problem: The system required complicated screen:pump interaction Solution: Turnkey design led by the pump team performed the conceptual design, site design, modeling, and execution Benefit: Fast project performed under planned budget
  20. 20. Case Study: Flat Panel Wedgewire Array Project: Fish Passage Screening Problem: A hydro project required fish friendly screening for a fish attraction facility Solution: A bank of wedgewire screens with a custom airburst system Benefit: Successful project with “best screens USACE had ever seen” ahead of schedule
  21. 21. Case Study: 316(b) for Oil & Gas Project: Oil & Gas Terminal Problem: An Oil & Gas developer was preparing an offshore terminal. Solution: A CFD analysis of the site & development of an innovative sensor scheme. Also provided technical & communication strategy support. Benefit: Practical & constructable modification to the screen to comply with regulations.
  22. 22. Case Study:Thermal Power Hatchery Intake Project: Thermal Power Intake Problem: A regional power utility needed to modify their intake structure to comply with regulation. Solution: A turnkey equipment package including screens, piping, and an airburst. Benefit: Successful project integrated with existing work ahead of schedule
  23. 23. Case Study:Aquatic Filter Barrier Project: Fish protective filter for art project Problem: Fish concerns for public art project Solution: Aquatic filter barrier system to protect fish eggs & larvae Benefit: Enabled project to progress
