  1. Reinventing the toilet

  2. Gates Foundation challenge

  3. Condensing nanobeads Waterless flush system Nano-sprayer Hollow fibre membrane Pathogen free water

  4. Action

  5. Hollow fibre membrane

  6. The membrane

  7. Membrane data highlight

  8. Condensing nanobeads Pathogen free water

  9. Condensing

  10. Condensingresults Initial data sets benchmarking standard glass media have shown ~ 40 % water capture from the vapour stream

  11. Drainage rate (or passive collection) 32 . 0 ° 32˚ 67.7˚ 78.7˚ Increased hydrophilicity apparently enhances moisture retention Does hydrophobicity govern drainage efficiency? • Synthetic urine vapour. Flow rate (4 LPM), BV (0.13 L), v (2.9 m/min), EBCT (1.95 s), temperature differential (< 2°C)

  12. Nano-sprayer

  13. Weetabix challenge After 2 months at room temperature: dewatered and mould free

  14. Next steps...
