Hydrovolta develops modular and project-engineered systems for brackish groundwater, hard water, and saline sources. Our systems recover more usable water with significantly lower residual brine than conventional membrane treatment. Where the concentrate has the right chemistry, we evaluate brine valorization pathways for selected chemical and mineral recovery.

Each of the following constraints has an active Hydrovolta deployment behind it.
RO strips nitrate and everything else — including calcium and magnesium the output still requires. When the target is NO₃¯ compliance without full demineralisation, selective electrodialysis is the answer RO cannot give you.
At silica above 60–80 mg/l combined with high hardness, RO membranes foul before the economics can be demonstrated. Acoustic cavitation prevents scaling at nucleation — before chemistry establishes itself on the membrane.
RO produces 25–50% brine. Inland sites with no coastal or river discharge face a disposal liability that kills the business case before technical evaluation begins. At 2–5% residual brine, the constraint changes character entirely.

SonixED™ combines electrodialysis reversal, ultrasound-assisted scaling control, and a proprietary selective membrane coating. Developed through institutional research partnerships over eight years. Patent granted 2021. Projects, pilots and pipeline across four continents.
Electric potential drives selected ions through membranes. Polarity reversal cleans membranes without chemical intervention. Stable output under variable feed TDS.
Acoustic cavitation at the membrane surface prevents silica and hard-water scaling. 50–90% reduction in CIP cycles in validated operating contexts. Extended membrane lifespan.
Custom membrane coating removes nitrate, sodium, chloride, fluoride while retaining calcium and magnesium. Mineral-balanced output. No post-treatment remineralisation required.
A walkthrough of active Hydrovolta equipment — from the SalinBloc™ containerised unit to the treatment stack inside.
Projects are labeled accurately by maturity. Hydrovolta has active equipment generating operational data, a contracted utility pilot, and signed LOI and MOU-stage pipeline across four continents.
Seawater-intruded coastal aquifer at approximately 7,000 ppm TDS. SonixED™ delivering saline water desalination with integrated downstream brine valorization. Funded by the Flanders Climate Action Program. Hydrovolta’s primary integrated reference site.
Selective nitrate and salinity removal across three public utility sites — supplying clean water for drinking, irrigation, agriculture, and livestock. Cloud telemetry and regulatory monitoring active. Hydrovolta’s primary utility reference internationally.
Development-stage project for nitrate and salinity co-contamination at a remote site. High-recovery treatment and minimal brine disposal are central to the technical and economic case.
Development-stage opportunity for selective ion recovery from deep brackish groundwater and brine streams. Pilot design in progress. MOU signed.
Hydrovolta works with organisations that control a brackish groundwater source or process water stream, face a concrete water quality challenge, and need a solution that has been technically validated before full capital commitment.
We understand how projects are funded — through development bank financing, climate action programmes, bilateral aid, or industrial capital budgets. We have navigated all of these pathways in Belgium, Morocco, and Australia.
For government and public authority buyers: We are familiar with the reporting, governance, and milestone structures of development finance institutions and government climate programmes.
Submit source water chemistry, TDS, target use, flow requirements, and any brine analysis. Our engineering team will assess whether SonixED™ or a brine valorization pathway is the right answer for your application — and tell you honestly if it is not.
No commercial obligation. All assessments are based on submitted water chemistry data.
