  2. Presentation Outline • Problem Statement • Objectives • Background Research • Final Design • Validation • Recommendation • Acknowledgements

  3. Problem Statement • 1 billion people live without access to improved drinking water (WHO). • Solving this problem for the Maasi tribe would be a step toward solving the world problem. • This is an engineering problem. Our team is looking for a solution to the problem.

  4. Objectives • A filtration system in which Maasai can take ownership. • Design, Build and Test a Slow Sand Filter. • Create an instruction manual to build a SSF. • Provide direction to assemble inexpensive water test kit. • Conduct Artemisia research to characterize Artemisian content in different species.

  5. Background Research • Darcy’s Law • Ceramic Filtration • Ceramic Manufacturing • UV light • Slow Sand Filtration • Kenya Research

  6. Background Research • Design Concepts: Ceramic Filtration Slow sand filtration UVC process

  7. Background Research • Concept Selection

  8. Final Design • Slow Sand Filter

  9. Final Design • Filter Specifications:

  10. Final Design • Test Kit Specifications:

  11. Final Design • Filtration Process

  12. Validation • Flow rate - 1. 66 L/min • Coliform - Absent • Bacteria Count - • Cost - 10 USD = 70KSH • Construction - < 1 Day • Schmutzdecke development time Three Weeks • Life • Sand = 5 years • Schmutzdecke – clean when flowrate drops

  13. Validation

  14. Validation

  15. Recommendations • The filter works and should be implemented.
