Take the brine stream off your mine site.
Contact water, RO reject from your existing plant, pit-dewatering concentrate — anything in the 5,000 to 50,000 mg/L TDS band that currently ends up in a pond, a truck or an injection well. Desalus funds, builds, owns and operates the treatment that closes the circuit at 99%+ recovery and holds your discharge compliance — you simply buy back clean water at an attractive rate per thousand gallons, with zero brine and zero reject left on site.
Your reject stream is the line item that never stops growing.
Every mine water circuit ends somewhere. Contact water and pit dewatering keep coming, your existing RO plant tops out and hands you a concentrate, and that concentrate has nowhere to go inland but a pond, a tanker or a deep well — each one a cost, a permit and a liability that scales with production.
- Disposal is recurring opex, not a one-off — hauling rates, pond liners, injection fees and monitoring climb every reporting period.
- Recovery collapses as influent TDS approaches 50,000 mg/L, so your plant cycles the same water and still rejects volume you have to move off site.
- Scaling, fouling and unplanned downtime on the reject end put discharge compliance — and the mining licence behind it — at risk.
What your reject really costs per tonne hauled
The harder your water gets, the more it costs to truck out what RO can't take. Desalus removes the reject stream that drives the curve.
This isn't a bigger membrane. It's the end of the disposal stream.
Desalus runs as a full treatment service built around your mine water circuit — taking the streams your plant rejects and closing them out so there is no concentrate left to handle.
99%+ recovery, no reject
Treat contact water and RO reject to near-total recovery and eliminate the concentrate entirely. No ponds, no liners, no tankers, no injection wells.
Lower water cost, zero capital
No capital outlay and no operating burden. Desalus funds, builds and runs everything — you pay only for clean water delivered, at an attractive rate per thousand gallons that beats your current all-in treat-and-dispose cost.
Compliance held, not chased
No brine means no discharge consent to defend and no pond to monitor — predictable zero-liquid-discharge operation that keeps your licence clean.
Built for 5k–50k mg/L
Engineered for the inland brackish-to-brine band where alternative designs and standard RO lose recovery — exactly your hardest streams.
Water back to the community
Recovered water and locally produced fertilizer leave a positive footprint around the operation — water and food security for the region.
Operated to your uptime
Desalus delivers treatment as a managed service — configured, run and optimized around your flows, your TDS and your availability targets.
Built for the streams that stall your existing plant
From mildly brackish dewatering to near-saturation RO reject and process brine, Desalus is designed for 5,000–50,000 mg/L total dissolved solids — the band where your recovery flatlines and the reject volume you have to move off site climbs.
The highlighted band is the Desalus operating window — precisely where mine water circuits get stranded today.
What happens to your reject stream
Same contact water and concentrate, three very different operating outcomes.
| On the operation | Desalus | Evaporation ponds | Conventional RO |
|---|---|---|---|
| Water recovery | 99%+ | Low — lost to evaporation | Stalls at high TDS |
| Reject / brine stream | None | Permanent pond | Yes — hauled or injected |
| Capital you outlay | None — Desalus owns & operates | You fund & build | You fund & build |
| What you pay for | Clean water, per 1,000 gal | Disposal, forever | Power + disposal |
| Recovered salts → fertilizer | Desalus recovers & sells | None | None |
| Discharge compliance | ZLD — held | Pond risk | Consent under pressure |
| Your all-in water cost | Lowest & predictable | Highest | High |
From water report to a closed circuit in four steps.
It runs on your numbers. Send Desalus a full-panel water quality and volume report for your contact water, RO reject or dewatering concentrate, and you'll get a site-specific picture of recovery, your clean-water rate per thousand gallons, and the capital and disposal costs you avoid.
Start with your water reportSend your full-panel report
Submit water chemistry and flows for each stream through the Desalus contact form. The fuller the panel, the tighter the design.
Get a site-specific model
Desalus quantifies recovery, your clean-water rate per thousand gallons, and the capital, haulage and disposal costs you avoid for your exact water.
Desalus builds & operates it
Desalus capitalizes, installs and runs the KNeW Process, Zix-Zak ion exchange and No-Briner systems around your circuit and uptime targets — no capex or operating burden for you.
Buy back clean water, waste-free
You purchase clean water at your agreed rate per thousand gallons, the reject stream never forms, and the recovered salts become farm-grade fertilizer Desalus markets — which is how your water price stays low.
Raise profit. Eliminate waste. Flourish community.
The award-winning systems behind the Desalus service take your hardest mine water streams and turn an open-ended disposal liability into reliable, affordable clean water — with nothing left to waste.
What mine water managers ask first
Can this take the reject from my existing RO plant?
Yes — that's a primary use case. Desalus treats the concentrate your plant already produces, along with raw contact water and dewatering streams, recovering 99%+ of the water and eliminating the reject. You keep your front-end plant; Desalus closes out the stream it can't.
How does the Desalus model work — what do I actually pay?
Desalus capitalizes, builds, owns, operates and maintains the treatment plant on your site. You don't buy equipment or run anything — you simply purchase the clean water Desalus produces, at an attractive rate per thousand gallons. Because Desalus recovers and sells the resulting farm-grade fertilizer, we can price your water below conventional haul-and-dispose alternatives while leaving zero brine and zero reject. The fertilizer revenue is Desalus'; your benefit is cheaper, predictable water and no disposal or tailings liability.
Is this seawater desalination?
No. Desalus is built for inland brackish water and brine at 5,000–50,000 mg/L TDS — mine sites with no ocean outfall and nowhere to put a reject stream. That constraint is exactly what makes a zero-liquid-discharge result valuable on a mine.
How does it affect my discharge compliance and uptime?
With no brine to pond, haul or inject, there is no reject-driven consent to defend and no pond to monitor. Desalus runs as a managed service designed around your availability targets, so the treatment that protects your licence is operated to a defined uptime.
What do I need to get a number for my site?
A full-panel water quality analysis and the flows for each stream — contact water, RO reject, dewatering concentrate. Submit them through the contact form on desalus.com and Desalus returns a site-specific model of recovery, your clean-water rate per thousand gallons, and the capital and disposal costs you avoid.
