  1. Global Water Experiment International Year of Chemistry 2011 American Chemical Society Sponsors

  2. Live Webcast with NASA – September 22, 2011 @ 10:00am • ACS and NASA partnered to launch a live webcast on NASA’s Digital Learning Network (DLN). Pacific High school was selected along with 2 other schools in the United States to participate in a live webcast, with ACS and NASA scientists (located at Johnson Space Center) who explained and answer questions related to water purification processes, the IYC global water experiment, and water purification on NASA’s International Space Station.

  3. Lab – Water: No Dirt, No Germs • Possibly the biggest chemistry experiment ever.

  4. Purpose • To raise awareness of the critical use of chemistry to provide one of the most basic human needs - Safe, Clean Drinking water.

  5. Research • This lab will explore the role water has in society and the environment.

  6. Water: No Dirt, No Germs • Use household materials to build a water filtration unit and identify the efficiently of different filtration materials

  7. Background • By 1911, water treatment was becoming common in Europe and North America.

  8. Waterborne disease • In developing countries 4 out of 5 illness are caused by waterborne diseases. • 1.1 billion people still lack access to improved drinking water. • 2,213,000 deaths annually.

  9. Natural Disasters • After Tsunami in 2004 and Japan in 2010 and Hurricanes like Katrina, there is always large increase in water bourn diseases such as cholera, Hepatitis A, Typhoid fever, Malaria, and Dengue Fever.

  10. Waterborne disease • Waterborne diseases such as typhoid fever and cholera are still around, killing thousands of people each year, even though chemical technology tools for clean water are available.

  11. Number of cases of waterborne disease

  12. Waterborne disease in USA

  13. Transmission of disease through water

  14. Eliminating Waterborne Disease • With simple household materials, water can be filtered and disinfected to produce clean safe drinking water for the world, virtually eliminating waterborne disease.

  15. Lab – No Dirt, No Germs • This lab will replicate two main steps of drinking water treatment: • Clarification • Disinfection

  16. Clarification • To remove solid debris from natural or waste water • Involves four steps: • Aeration • Coagulation • Sedimentation • Filtration

  17. Clarification – Step 1: Aeration • Aeration: adds air to water • Allows gases trapped in water to escape. • Adds oxygen to the water

  18. Clarification – Step 1: Aeration • Done by shaking and pouring water back and forth between two containers

  19. Clarification – Step 2: Coagulation • Coagulation: removes dirt and other floating solid particles by chemically sticking them together in FLOCS (clumps of Alum and sediment).

  20. Clarification – Step 2: Coagulation • Done by adding ALUM and stirring for 5 minutes

  21. Clarification – Step 3: Sedimentation • Sedimentation: gravity pulls particles of FLOC to bottom of container. • Clear water remains at top and is drained and filtered.

  22. Clarification – Step 3: Sedimentation • Done by letting ALUM treated water sit for 20 minutes.

  23. Clarification: Step 4 - Filtration • Filtration: sand and pebble filter removes most impurities that remain in the water

  24. Filtration Unit

  25. Clarification: Step 4 - Filtration • Done by pouring the top ¾ of the untreated water into a filter and collecting the treated water.

  26. Disinfection • Disinfection: Drinking water chlorination • A small amount of chlorine is added to large volumes of drinking water. • Destroys germs (Bacteria & Viruses).

  27. Disinfection • Done by adding enough chlorine (bleach) to destroy germs, plus a little more to fight new germs that water may encounter before water reaches your home. • Extra chlorine is called “chlorine residual”

  28. Disinfection • Chlorine test strips detect the chlorine residual.
