  1. Global Reflections on Small-Scale Systems

  2. Agenda • End of the semester details • Where to go from here… • Your reflections on what you learned • Flow control design project

  3. End of the semester details • Team evaluation form (due 12/8) • Course evaluation form (due 12/8) • Flow control report (due 11:59 pm 12/8) • Presentation (12/17 at 9:00 AM)

  4. CEE 332: Hydraulic EngineeringSpring 2005 • “The application of fluid mechanics and other science and engineering disciplines in the development of structures, projects, and systems involving water.” • Will include pipeline design, pipe network, transients, pumps, open channel flow • Design project will be a small community water supply transmission line and distribution system

  5. CEE 452: Water Supply EngineeringFall 2005 • Analysis of contemporary threats to human health from water supplies • Criteria and standards for potable-water quality • Water-quality control theory • Design of water supply facilities

  6. Additional Opportunities • CEE 492: ESW Cornell Chapter Project: Turbidity removal technologies for Honduras • Organizations

  7. M. Eng. Program • Currently there are 3 distinct Environmental Engineering M. Eng. programs at Cornell • Water Quality • Environmental Fluid Mechanics and Hydrology • Environmental and Water Resources Systems Engineering • I am hoping to design a more flexible M. Eng. curriculum…

  8. Small Scale Water Treatment for Turbid Surface Water (05-06) • Selection, evaluation, and improvement of particle removal technologies for small scale community and/or household water treatment • Collaboration with Agua Para el Pueblo in Honduras • Will likely involve pilot scale evaluation (lab testing)

  9. Topics in Review • Public Health and Water • Multiple barriers, Multiple exposures • Sedimentation/coagulation • Filtration theory • Disinfection • Creative design process • Flow control • Technology Selection • Staged Sustainable Space

  10. Oral Report Topics • Alternative coagulants • Ceramic filters • Arsenic removal • Biosand filters • Cochabamba • SODIS • Ethics of Aid

  11. What did you learn in this course? • Each person (10 minutes) • write down 3 to 10 things that you learned in this course • In groups of 3 or 4 (10 minutes) • Share what you learned • As a class • Each person shares their top 1 or 2 concepts • Open for comments/reflections • Collect cards

  12. Creative Design Process • How have you used what you learned about the creative design process?

  13. Flow Control Design Project:Device Works… • Test it with clean water • Test it with turbid water • Plot flow rate vs. time • Report should include all design calculations and performance measurements as well as proposals for improving the device • Include photos and detailed drawings • Show in detail how this device would be used as part of a treatment process

  14. Flow Control Design Project:Device Fails… • Document why the device fails • Document changes you made to the device to improve its performance • Include data that shows the failure • Include design equations and analysis of the failure mode • Propose methods to improve the device or explain why this device isn’t a viable solution • Include photos and detailed drawings

  15. Flow Control Future • It is very likely that the best ideas from the class project will be incorporated into the alum feed unit that is being design for a community in Honduras • I hope to see you often in the next days as you work on your designs!

  16. Sustainable Water: currently only exists as a brainstorm
