An atmospheric water generation (AWG) prototype that works in almost all humidity conditions to generate potable water.

With more than 1.9 billion people living in water scarce areas, the need for a reliable, sustainable source of clean water is imperative. CSIRO scientists have developed a device that can harvest potable water from straight out of the ambient air, using metal-organic frameworks (MOFs).

Atmospheric water generation prototype

This technology stands out as it can operate in the majority of humid conditions found on the globe. Optimal operational range starts at 30 per cent Relative Humidity upwards, with more limited performance down at the very dry 15 to 20 per cent RH. It has been designed to maximise energy efficiency per litre of water produced. Its operational versatility means that it can be scaled to suit the required need from small litre quantities to larger volumes.

We have a patent for the material production at the heart of the device, which is licensed to a local Australian manufacturer. The AWG prototype is also protected through a provisional patent.

We are exploring options to establish a spin out company to produce and sell devices based on this technology. Interested investors are encouraged to contact the commercialisation team to explore potential investment.

Technology

  • A polymeric coating is added to the respirator's wool fibres. This creates a permanent surface charge on the fibre surface that destroys microbes' cell walls. The coating is incompatible with human cells and doesn't harm them
  • The electrostatic filter material comprising biocidal wool fibres and clean polypropylene fibres also contain extremely high levels of electrostatic charge, which produce extraordinarily good filtration performance
  • Positive charges on wool fibres and negative charges on polypropylene fibres are evenly split between the two components, however the highly charged material feels totally charge-free because the net charge of positive minus negative charges is exactly zero
  • Charges from the biocidal treatment and the electrostatic charging co-exist in the material to form a highly effective biocidal fine particle filter. This is not commonly the case and represents the main value of the technology
  • Stored electrostatic charge is not affected by high humidity and regenerates to a large extent after full immersion in water as the material dries. It is therefore suitable for garment manufacture and can be washed many times, while biocidal and aerosol barrier properties are maintained.

Applications

  • Air pollution respirators against smog, thunderstorm asthma or propagation of disease pathogens
  • Cabin filters for cars, haulage, public transport or airlines
  • Air-cleaner units and air-conditioning
  • Mattress ticking and bedding
  • Curtain materials
  • Knitwear and clothes.

Intellectual property

A provisional patent covering the combination of biocidal and electrostatic barrier action for wool-polypropylene fibre blends and fabric structures derived from those blends has been examined by the International Patent Office. The International Examiner report considers all claims of the patent to be novel, inventive and suitable for industrial application.
