01
Sodium degrades the soil
Saline irrigation water degrades soil structure and reduces crop yield. The damage accumulates over seasons, and it is the sodium rather than the total salinity that does most of it.
Irrigation water
Brackish water for irrigation, without wasting most of the well.
Saline irrigation water degrades soil structure and reduces crop yield. Reverse osmosis will desalinate it and send a quarter to a half of the borehole to a disposal problem you may not have. SonixED™ removes sodium and excess TDS selectively, keeps the calcium and magnesium your soil wants, and leaves far less behind.

The problem
Saline groundwater irrigation costs you twice.
Once in the soil, once in the water you never get to use.
02
Demineralised water is not better water
Calcium and magnesium are beneficial to soil chemistry. A process that removes everything leaves you irrigating with water that has to be corrected before it is useful.
03
In arid geographies, waste is the constraint
Reverse osmosis typically sends 25–50% of the feed to brine. Where the borehole is the whole supply, that fraction is not a disposal line item — it is the limit on irrigated area.
Reference
Morocco — desalination for agriculture, in operation.
Morocco is Hydrovolta’s flagship active project: the first commercial demonstration of the integrated SonixED™ desalination and downstream brine valorization model.
Seawater-intruded coastal aquifers at approximately 7,000 ppm TDS. SonixED™ delivers saline water desalination for irrigation and drinking water supply. Residual concentrated brine is processed through downstream valorization for chemical recovery. Funded by the Flanders Climate Action Program.
Site data
Irrigated area served [PLACEHOLDER ha] · product TDS [PLACEHOLDER ppm] · recovery [PLACEHOLDER %] · in operation since [PLACEHOLDER].
The mechanism
Take out the sodium. Leave in the soil chemistry.
SonixED™ is electrodialysis reversal with ultrasound-assisted scaling control and a selective membrane coating.
SEL
Selective, not total
The membrane coating determines which ions move. Sodium and excess TDS are removed; calcium and magnesium are retained, so the water arrives at the field already suited to the soil.
REC
More of the borehole reaches the crop
Recovery of up to 98% in suitable applications, with 2–5% residual brine in selected cases. In an arid geography that difference is irrigated hectares.
US
Scaling does not stop the season
Acoustic cavitation prevents scaling at nucleation. Hard, silica-laden groundwater is the normal case in irrigation, not the exception, and it is what defeats conventional membranes.
Fit
Where this works, and where it does not.
Strong fit
Brackish boreholes in the 1,500–20,000 ppm TDS range. Sodium-dominated salinity damaging soil structure. Arid sites where disposal is constrained and every cubic metre counts. Schemes that want a pilot before committing capital.
Not the primary use case
Full seawater, where SWRO is typically preferred. Sources whose problem is organic or microbiological rather than ionic. Schemes that genuinely want demineralised water, which is a different process.

Engineering Assessment
Send the water data. We assess the fit.
TDS, sodium, hardness, target flow and irrigated area are enough to start. We tell you honestly when SonixED™ is not the right answer for your source.
