  1. Solar Chlorine Generator Sponsored by Dow Chemical Fall 2012 Nick Lubenetski, Kelly Helfrich, Brittany LaBadie, David Blyton

  2. Big Picture Problem: Every year there are millions of deaths resulting from contaminated drinking water Our goal: Is to make a simple cost effective water purification device that can be operated by a common person in Morocco

  3. Project Goals • Research and understand project background (solar, chorine generation, filtration) • Understand previous design failures and successes • Design a prototype for SUNU • Build first round prototype • Test and modify prototype • Write instruction sheet/video to be sent over with prototype • include safety information • Include a detailed final report with what we found and why we chose design • all research included

  4. Last Semester’s Project • What was accomplished • Prototype built • Sealed the container • Researched Scrubber systems

  5. How it works • Brine Water Used • Electrolysis • Chlorine generated reacts with harmful bacteria

  6. Positives of This Model • Cheap Method • All supplies are Accessible • Easy to Use • Generates Chlorine from Brine water

  7. Problems with Current Design • The current model is not solar • Release of very harmful chlorine gas • Purified water is not accessible • Installing Scrubber System is complicated

  8. What needs to be addressed • The release of harmful chlorine gas • Accessing the purified water • Making the system solar powered

  9. Research Our water How to purify it Bleach Carbon Filtration Chlorine Generation

  10. Our Water • Three basic categories • Protozoa • Bacteria • Viruses

  11. Bleach • Add specified amount of bleach • Wait 30-60 minutes until water is clear • Can purify 5,460 gallons for $4 • Only kills bacteria • May also need to be filtered

  12. Carbon Filtration • Activated carbon • What it’s best at removing • What it’s not good at removing • Silver or KDF-55 used to prevent bacteria growth

  13. Carbon Filtration Use • Water passes through mesh/screen filter • Passes through activated carbon filter • De-ionizing filter used

  14. Chlorine Generation • Effects of chlorine • Salt used for reaction • Forms hypochlorite • Used for water filtration

  15. New Design • Purpose • Application • Constraints • Bleach design

  16. Solid Works Design Bleach Storage Mixing Tank Carbon Filter Storage tank

  17. Addition of Bleach • Manual addition one time a month • Drains via gravity • Small amounts added • Calculations

  18. Mixing Tank • Continuously stirred • Feed streams (bleach/water) • Assumptions & calculations

  19. Storage Tank/Filtration • Storage tank • Stores purified water waiting to be filtered • Size • Underground to maximize space • Carbon Filtration • Pumped up from underground storage tank • Removes contaminants and dirt just before use or consumption
