Transcript

  • 1. 1<br />Reverse Osmosis Design: Designing Effective Reverse Osmosis Equipment for Industrial and Power Generation Applications<br />www.LayneWater.com<br />1<br />
  • 2. 2<br />Reverse Osmosis Equipment for Power Generation<br />Primary power generation Reverse Osmosis application is boiler feed water pre-treatment<br />Downstream of clarification and filtration<br />Upstream of demineralization polishing<br />Reverse Osmosis equipment performance directly impacts demin performance and acid/caustic usage. <br />www.LayneWater.com<br />
  • 3. 3<br />Reverse Osmosis Equipment Definitions<br />Osmosis<br />Pure water diffuses from the dilute side to the concentrated side of a semipermeable membrane.<br />Reverse Osmosis<br />High pressure is applied to the concentrated side of the membrane and pure water flows to the dilute side. <br />Net Driving Pressure<br />The pressure applied to the membrane to create the reverse osmosis. Typically 200 – 450 psi.<br />www.LayneWater.com<br />
  • 4. 4<br />Designing Reverse Osmosis Equipment for Power Generation<br />Four main components to an RO system<br />Element<br />Array<br />Stage <br />Pass<br />www.LayneWater.com<br />
  • 5. 5<br />Reverse Osmosis Equipment for Power Generation<br />RO Element types<br />Spiral wound<br />Hollow fiber<br />Large tube<br />Flat plate<br />www.LayneWater.com<br />
  • 6. 6<br />Reverse Osmosis Equipment for Power Generation<br />RO Array<br />How the elements are grouped together<br />Series<br />Parallel<br />www.LayneWater.com<br />
  • 7. 7<br />Industrial Reverse Osmosis for Power Generation<br />RO Stage<br />A series of elements linked together such that the reject (concentrated) water from stage 1 becomes the feed water for stage 2.<br />This is done to reduce wastewater and to increase the total recovery from the RO array.<br />www.LayneWater.com<br />
  • 8. A Two Stage RO System for Power Generation<br />www.LayneWater.com<br />
  • 9. Reverse Osmosis for Power Generation<br />RO Pass<br />An arrangement of elements where the permeate from pass 1 becomes the feed water of pass 2.<br />This is done to produce a final product that is more pure than what can be achieved using only one pass.<br />9<br />www.LayneWater.com<br />
  • 10. A Two-Pass Two-Stage RO System <br />www.LayneWater.com<br />
  • 11. 11<br />Using Multiple Passes to Improve Permeate Quality in a Power Generation Example<br />Note: Calculated results. Field efficiencies will likely be lower.<br />www.LayneWater.com<br />
  • 12. Using Multiple Stages to Reduce Wastewater in a Power Generation Example<br />Note: Calculated results. Field efficiencies will likely be lower.<br />12<br />www.LayneWater.com<br />
  • 13. 13<br />Critical Next Step!<br /> Download and read the complete whitepaper while it is still available:<br />Reverse Osmosis Design for the Power Generation Industry- What You Need to Know<br />http://www.laynewater.com/landing_ro_powerind.html<br />www.LayneWater.com<br />
  • 14. 14<br />Why Choose Layne for your Power Generation Reverse Osmosis Applications?<br />Total Water Expertise from Source to Discharge!<br />1. Complete filtration options – From large municipal to light industrial Layne has the technology<br />2. Hydrology – Layne can locate, quantify and compare all of your water source options <br />3. Well drilling – No water available? We can access water sources that are beyond the reach others<br />4. Pipeline Construction – 10 miles from a water source? Not a problem!<br />Get the whole story here!<br />www.LayneWater.com<br />
