  • No energy needed – gravity driven
  • No chemicals needed
  • Simple & robust
  • No or nearly no maintenance needed
  • Operational even for illiterates
  • Easily transportable, even hands-free as a backpack
  • Designed to help in emergencies and disasters

Filtration Technology

  • gravity driven dead end filtration with vertical flat sheet membranes
  • ULP-UF: ultra low pressure ultrafiltration: max. 0.08 bar
    – pore blocking: close to zero
    – cake layer removal: by gravity (sinks to the bottom and then to be removed)
    – process: pressure operated (instead of usual flow driven process)
  • ≈ 10 m2 membrane surface area, lifetime 10+ years
  • Min. capacity 1,200 L/d, practical measurements from 2,000 to 6,000 L/d
  • no spare parts necessary

Capacity

Although PAUL is known for a minimal capacity of 1,200 l/d, in-the-field measurements show a reasonably higher daily capacity, as can be seen PDF.
