Hydrophis helps
industry
buy less water.
We turn industrial wastewater into water for reuse and minerals to sell.
We use CO₂ as the process acid to recover water and calcium and magnesium minerals from industrial brine, ash and residue streams.

Use the water again.
Recover what is in it.
Industry already pays to buy, move and treat water. We recover water from its waste streams so it can be used again, and separate calcium and magnesium into mineral products.
Wastewater in
Desalination wastewater, ash rinse water and industrial residues.
Water back
Recovered water for reuse in the industrial process.
Minerals out
Separate calcium and magnesium products with value.
Six pilot campaigns between 2023 and 2026 on a 30 m³/day continuous rig at a full commercial scale seawater desalination plant and a fly ash reclamation plant in South Australia.
Explore the pilot programmeQuantitative XRD on filter-press cake measured calcium carbonate at 97%, magnesium carbonate at 99% and magnesium hydroxide at 98% purity by weight.

Start with the material.
Follow the evidence.
We start with what is actually on a site.
What we do
The process, the feed types, and what comes out.
The technology
and the patent
Chemistry, pre-concentration, and why it outperforms earlier brine-mineralisation methods.

Every project starts
with what is there.
- 01
Characterise
Characterise the material to establish exactly what is in the stream or the deposit, and the variables across it.
- 02
Design
Design the plant to the feed, adapting the chemistry and water system to the site's conditions.
- 03
Recover
Recover what has value by separating the useful minerals and recovering water for reuse.
