Nanomembrane Pervaporation


  • Descriptive Overview
    This is a nanomembrane pervaporation technology which can be used to separate water from solid and liquid contamination.
  • Use Case Details
    Household: Designed as a self-contained, household unit up to 10 users per day Multi-unit: Core processing technology could be scaled for school, or public/ community application
  • Regularly Scheduled Required Maintenance
    Membranes should be cleaned four times per year.
  • Use Cases
    • Single-stall Toilet
    • Multi-stall Toilet
  • Users per Day (Expected)
    Current design supports up to 10 users/day, but could be scaled to larger capacity
  • Users per Day (Maximum)
  • Type of Waste Treated
    Liquids Processing
  • Core Processing Technology
    Membrane Filtration
  • Processing Overview
    A hydrophobic membrane separates clean water from the contaminated urine. The clean water is then sent to a storage tank for later use.
  • Processing Capacity
  • Processing Parameters
    The pass through and efficiency of the pervaporation process increase when the pre-treated liquid stream is heated. Membrane is off-the-shelf. Specifications: Temperature: 70 deg C Pressure: 1 bar Heat Source: Process Heat Final Storage Volume: 22 L
  • Power Systems Overview
    Separate power system required. Residual heat from other processes is used to increase efficiency.
