Self-contained Toilet Wastewater Treatment

  1. Frontend - Eram Scientific eToilet with self-cleaning technology.
  2. Urine/Feces - Active anaerobic bioreactor.
  3. Liquid Processing - An electrochemical system oxidizes the wastewater at semiconductor anodes and water is reduced at the metal cathode to form H2. Chloride from urine is oxidized to reactive chlorine species, increasing disinfection. Final membrane microfiltration may be included for polishing.
  4. Solids Processing - Feces are macerated and the suspended fraction is treated with the liquids. Settled solids are evacuated once a year (approx. 10% volume).
  5. Power System - Solar panels with energy storage in batteries and/or grid electricity.
