Global Water Experiment

Global Water ExperimentInternational Year of Chemistry 2011American Chemical Society

SponsorsLive Webcast with NASA September 22, 2011 @ 10:00amACS and NASA partnered to launch a live webcast on NASAs 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 NASAs International Space Station.

Lab Water: No Dirt, No GermsPossibly the biggest chemistry experiment ever.

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

ResearchThis lab will explore the role water has in society and the environment.

Water: No Dirt, No GermsUse household materials to build a water filtration unit and identify the efficiently of different filtration materials

BackgroundBy 1911, water treatment was becoming common in Europe and North America.

Waterborne diseaseIn 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.

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.Natural Disasters

Waterborne diseaseWaterborne 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.

Number of cases of waterborne disease

Waterborne disease in USA

Transmission of disease through water

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

Lab No Dirt, No GermsThis lab will replicate two main steps of drinking water treatment:ClarificationDisinfection

ClarificationTo remove solid debris from natural or waste waterInvolves four steps:AerationCoagulationSedimentationFiltration

Clarification Step 1: AerationAeration: adds air to waterAllows gases trapped in water to escape.Adds oxygen to the water

Clarification Step 1: AerationDone by shaking and pouring water back and forth between two containers

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

Clarification Step 2: CoagulationDone by adding ALUM and stirring for 5 minutes

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

Clarification Step 3: SedimentationDone by letting ALUM treated water sit for 20 minutes.

Clarification: Step 4 - FiltrationFiltration: sand and pebble filter removes most impurities that remain in the water

Filtration Unit

Clarification: Step 4 - FiltrationDone by pouring the top of the untreated water into a filter and collecting the treated water.

DisinfectionDisinfection: Drinking water chlorinationA small amount of chlorine is added to large volumes of drinking water.Destroys germs (Bacteria & Viruses).

DisinfectionDone 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

DisinfectionChlorine test strips detect the chlorine residual.
