Function

Operational procedure:

  • 25 litre of untreated water is poured into the top of the unit, also called the dirty water container
  • The pre-filter removes coarse particles larger than 0.080 mm
  • The hollow-fiber ultrafiltration membrane cartridge then stops all suspended particles and pathogens larger than 20 nanometres
  • Particles and microbes larger than 20 nanometres stay on the dirty side of the membrane and clean/purified water passes through the membrane
  • Purified water can be collected from any of the four taps
  • The backwashing handle allows semiautomatic backwashing; when it is pulled down and released, pathogens and dust particles on the dirty side of the membrane are lifted by back pressure and then flushed out into the red backwash container.
