“Hot bubbles” have proven highly effective in the destruction of various solutes, especially viruses and bacteria. Taking advantage of the properties of a bubble column, this low energy, simple solution destroys contaminants without high pressures, chemical additives, or expensive membranes. Using hot gas means energy costs are low and solution temperatures remain relatively low.
Heating water takes more than 3,000 times the energy for the same volume of air, but that’s not even the most significant part. The physical effect of different gases is as, if not more significant. The discovery of CO₂ unique ability to kill viruses and bacteria is a paradigm shift leading a complete reassessment of biological immune and respiratory systems, with implications from water sterilisations through treating COVID-19.
Hot CO₂ bubbles destroy virus and bacteria on contact rendering them harmless and the water sterilised.
Specially designed naturally based surfactants are used to bind heavy metals in a counterflow bubble column. Contaminants are then removed via foam floatation, a simple, low cost and highly scalable solution already used at enormous scale in mining and water treatment facilities globally. Using naturally based surfactants means no environmental concerns.
Heavy metal pollution is often naturally occurring, with the combination of high toxicity and very low concentration making treatment expensive. We have developed a simple process that specifically binds heavy metal ions, allowing safe removal in a simple single stage process. Using only a naturally derived binding compound and air, this foam floatation process is simple, highly efficient and enormously scalable, ideal for large mine or groundwater treatment even in remote locations.
Our specially designed surfactant physically binds the heavy metal ions allowing them to be captured in the resulting foam. Foam is then collected from the surface, collapsed and disposed. Depending on the application, the surfactant may even be reused.
Similar to Heavy Metal removal, a Bubble Column foam flotation process and targeted surfactant is used to remove over 80% of PFAS in a single step. With surfactant and air the only inputs, this process is simple, cheap, and safe operate at large scale. No heat, pressure or toxic chemicals used or produced.
Using the same process as our Heavy Metal removal technology, our specially designed surfactant binds the full range of PFAS molecules and safely floats then off allowing simple, safe disposal. With the only inputs our naturally based surfactant and air, costs are minimised, and no harmful by-products are produced, making this the safest PFAS removal process for both water and soil applications.
Our specially designed surfactant physically binds the PFAS chains allowing them to be captured in the resulting foam. Foam is then collected from the surface, collapsed and disposed.
An extension of the hot bubble water sterilisation process, this platform recycles CO2 twice:
1. First to sterilise water in the bubble column; &
2. A secondary stream of now super-saturated CO2, is then pumped into the greenhouse to boost plant production & watering
High carbon dioxide concentrations during the day make plants more productive because photosynthesis relies on using the sun’s energy to synthesise sugar from carbon dioxide and water. The moisture from the saturated combustion gases condensates on the glass surface of the greenhouse providing the moisture for watering.
This new bubble column greenhouse technology provides a new source of disinfected water for irrigation to primary industries and remote communities, and a source of pure water and CO2 that will boost plant production in greenhouses with virtually no operating costs.
A by-product of this process is pure distilled water which can be utilised for kidney dialysis in remote settings. Indigenous folk can access kidney dialysis in regional settings rather than travelling to Darwin or Adelaide for treatment. Forty litres of distilled water is required for each kidney dialysis treatment.
We identify specific water-related problems in communities, develop tailored solutions, and then scale these solutions for similar communities. Our projects range from water sterilisation to heavy metal removal, and beyond.
