ULTRON Liquid Processing Technology


  • Descriptive Overview
    CalTech has built on their existing electrochemical reactor (ECR) technology to develop the ULTRON system for urinal retrofits or liquid disinfection. Both the urinal retrofitting kit and the portable disinfection system contains a number of ECRs connected in parallel in order to reach the desired flow rate and application.
  • Use Cases
    • Single-stall Toilet
    • Multi-stall Toilet
  • Frontend Description
    Can be retrofit with a urinal for urine processing, or connected to other frontend configurations
  • Users per Day (Expected)
    Scalable; modules can be connected in parallel for increased flow rate. Maximum users per day of 50 is estimated based on likely use-casel for the ULTRON ECR. Larger systems in are in development with other partners to serve several hundred users per day.
  • Users per Day (Maximum)
  • Type of Waste Treated
    Liquids Processing
  • Core Processing Technology
  • Processing Overview
    An electrochemical system oxidizes the urine and flush water at a semiconductor anode and water is reduced at the metal cathode to form H2.
  • Processing Capacity
    10 L/hr for portable liquid disinfection; 30 L/hr as a urinal retrofit
  • Power Systems Overview
    Requires grid power
  • Currently in Active Development
  • Commercialization Status
    Seeking Licensees
  • Commercialization Activities
    Commercialization partners to license as a component, or to bring technology to market
