Hydro2050

Purifying water Naturally

Lake Albert, Wagga Wagga

The lake that closed each summer due to blue-green algal blooms, and the summer it didn't.

Five units in February 2025, and thirteen months of independent testing. The full film is on the page.

Water technology, Australia

Water treated with air, not added chemicals.

Hydro2050 is a self-contained water treatment system. It generates oxygen and ozone from the ambient air and injects these into water through trillions of ultrafine nanobubbles.

Cyanobacteria

182,385 to 936 cells/ml

Lake Albert, Wagga Wagga, New South Wales, over two weeks. No laboratory named.

Industries

Where Hydro solves key water issues

Dams, lakes and ponds

Controls harmful algal blooms, cyanotoxins, E. coli and organic pollutants. Clears odours and low dissolved oxygen, with no toxic chemical residues.

Learn more

Food Production

Stronger roots and higher yielding plants under irrigation. Higher dissolved oxygen for fish, cleaner drinking water for stock, and farm wastewater treated for reuse.

Learn more

Wastewater treatment

Improved aerobic digestion and faster breakdown of organic pollutants. Reduced odours, better solids removal and higher quality water for reuse.

Learn more

Drinking water

Water sanitation and security for remote communities. Chemical free, low enough power to run off grid, and removes odour and taste contaminants.

Case Studies

Evidence

Four of the ten case studies.

  1. Review of Scientific Evidence, Nanobubble Technology

    An independent 2025 review of the peer-reviewed research and case studies on nanobubble technology, by Houd Research Group.

  2. Cyanobacteria Control, Lake Albert

    Cyanobacteria 182,385 down to 936 cells/ml in two weeks. Wagga Wagga, New South Wales.

  3. Algal Bloom Control, Jubilee Lake and Willunga Dam

    Dissolved oxygen 8.1 up to 21.4 ppm in two hours, and nitrate 6.64 down to 0.63 mg/L during treatment. Two South Australian water bodies.

  4. Water Reuse, Coliform, E. coli and Algae Reduction

    E. coli 200,000 down to 380 MPN/100mL, and colony forming units 32,500 down to 33 per ml. Two horticultural facilities.

The evidence behind the process

Research-led, scientifically grounded, independently investigated

Built on science. Proven in practice.

Hydro2050 applies established advanced oxidation and ultrafine bubble technologies that are supported by decades of international research. That work is strengthened through collaboration with leading Australian researchers, universities, and industry partners to ensure solutions are scientifically rigorous, environmentally responsible, and operationally effective.
