Space Mission Water Purification Still Challenge

Design a water purification still using lab apparatus to transform wastewater (urine, sweat, breath, coolants, transpiration) into drinking water. Utilize a large beaker, small beaker, kitchen foil, black paper, and rubber bands. Collaborate in pairs to create a solar still design within 15 minutes. Explain the process using terms like solid, liquid, gas, solution, solvent, solute, evaporate, water molecules, and condense.

Presentation Transcript

  1. Long Flight Survival: Water purification How could we get drinking water from the large amounts of wastewater that we generate on this mission?

  2. Where does the waste water come from? • Urine • Sweat • Breath from respiration • Coolants for the many heat generating machines • Transpiration from plants in the spacecraft’s garden

  3. Your challenge is, using this lab apparatus, set up a water purification still which would give you, over enough time, water fit to drink. • Large beaker • Small beaker • 15 x 15 cm kitchen foil • 15x 15 cm black paper • 3 x strong rubber bands In pairs, design a suitable still. You have 15mins to produce a diagram showing how it could be set up

  4. Possible design for a solar still

  5. Now explain how your solar still works. Use the following words • solid • liquid • gas • solution • solvent • solute • evaporate • water molecules • condense
