Zero liquid discharge that pays for itself.
ZLD has a reputation: necessary, but ruinously expensive once thermal evaporators and crystallizers enter the picture. Desalus reaches true ZLD on inland water at 5,000–50,000 mg/L TDS a different way — Desalus funds, builds, owns and operates it all, recovering over 99% as clean water you buy back at an attractive rate per thousand gallons. It pays for itself through a low water rate and no capex or disposal — not through fertilizer you sell.
Conventional ZLD makes you pay to boil your problem away.
When regulators mandate zero liquid discharge, the textbook answer is a brine concentrator followed by a thermal crystallizer — equipment that turns concentrate into solid waste by sheer energy. It works, and it bleeds money every hour it runs.
- Thermal ZLD is an energy sink. Crystallizers consume enormous power and steam to evaporate water you should have kept.
- The output is waste, not value. You spend a fortune to produce a mixed-salt cake that still has to be landfilled.
- Capex and downtime compound. Scaling, corrosion and maintenance make thermal trains some of the most fragile assets on site.
Where the money goes in conventional ZLD
The closer thermal ZLD gets to dryness, the steeper the bill. Desalus reaches ZLD without that climb.
ZLD shouldn't be a penalty. With Desalus it's a profit center.
Same regulatory outcome — zero liquid discharge — reached without the thermal cost and with saleable product on the other side.
It pays for itself
No capital outlay and no operating burden — Desalus funds, builds and runs it all. You pay only for clean water at an attractive rate per thousand gallons, with no disposal or thermal cost, so meeting ZLD costs less than your old treat-and-dispose economics. Desalus sells the recovered fertilizer, which is what keeps your rate low.
No crystallizer required
Desalus reaches ZLD without a thermal evaporator-crystallizer train — eliminating the single biggest energy and maintenance burden in conventional ZLD.
99%+ water recovered
Water leaves as clean product, not steam. You keep nearly all of it instead of paying to evaporate it.
Solids become a product
Instead of a landfill-bound salt cake, the dissolved solids are recovered as pure, farm-grade fertilizer that Desalus markets — funding the service and supporting regional agriculture.
Compliance, locked in
True zero liquid discharge satisfies the mandate cleanly — no outfall, no brine permit exposure, no disposal liability.
Delivered as a service
Engineered, operated and optimized around your effluent — built on the IChemE award-winning No-Briner and KNeW Process.
ZLD economics in the band thermal trains punish most
Between 5,000 and 50,000 mg/L TDS, the gap between economical recovery and brute-force evaporation is widest — and that's exactly where Desalus delivers ZLD that pays.
Right where thermal ZLD gets most expensive, Desalus keeps the economics in your favor.
Thermal ZLD vs. ZLD that pays for itself
Two routes to zero liquid discharge — one drains the budget, one funds itself.
| Outcome | Desalus | Thermal ZLD (crystallizer) | Conventional RO + pond |
|---|---|---|---|
| Reaches true ZLD | Yes | Yes | No — pond remains |
| Energy demand | Low | Very high | Moderate |
| Water recovery | 99%+ | High but costly | Stalls inland |
| End product of solids | Pure fertilizer | Landfill salt cake | Pond residue |
| Maintenance burden | Low — Desalus operates it | Heavy | Moderate |
| Capital you outlay | None — Desalus owns & operates | You fund & build | You fund & build |
| What you pay for | Clean water, per 1,000 gal | Energy + disposal | Power + disposal |
| Your all-in water cost | Lowest & predictable | Highest | High |
From effluent report to self-funding ZLD in four steps.
It starts with your numbers. Send Desalus a full-panel effluent quality and volume report, and you'll see exactly how zero liquid discharge can pay for itself on your site.
Model your ZLDShare your full-panel report
Send your effluent quality and volume data through the Desalus contact form. The richer the panel, the sharper the ZLD model.
Get a ZLD economics model
Desalus quantifies recovery, your clean-water rate per thousand gallons, and the thermal, capital and disposal costs you avoid on your exact effluent.
Desalus builds & operates it
Desalus funds, installs and runs KNeW Process, Zix-Zak ion exchange and No-Briner to reach ZLD without a thermal evaporator-crystallizer train — no capex or operating burden for you.
Comply and buy back clean water
Zero liquid discharge is met and you simply purchase clean water at your agreed rate per thousand gallons. The recovered salts become fertilizer Desalus markets, which is how your water rate stays low.
Raise profit. Eliminate waste. Flourish community.
ZLD doesn't have to be the line item that hurts. The award-winning Desalus systems make zero liquid discharge the line item that pays.
What ZLD decision-makers ask first
How is this different from thermal ZLD?
Conventional ZLD relies on brine concentrators and thermal crystallizers that evaporate water using large amounts of energy, producing a landfill-bound salt cake. Desalus reaches true zero liquid discharge without that thermal train — recovering over 99% of the water as clean water and the dissolved solids as farm-grade fertilizer instead of waste.
What does "pays for itself" mean in practice?
It pays for itself on the cost side, not by selling you fertilizer. Desalus funds, builds and operates the plant, so you outlay no capital and carry no thermal, maintenance or disposal cost — you pay only for clean water at an attractive rate per thousand gallons. Because Desalus recovers and sells the fertilizer itself, it can price your water below your old treat-and-dispose economics, so meeting ZLD frequently costs less overall. Your site-specific model puts numbers to it.
How does the Desalus model work — what do I actually pay?
Desalus capitalizes, builds, owns, operates and maintains the facility — you invest no capital and run nothing. You simply purchase the clean water Desalus produces, at an attractive rate per thousand gallons. Because Desalus recovers and sells the resulting fertilizer, we can price your water below conventional thermal-ZLD and treat-and-dispose alternatives while leaving zero waste. The fertilizer revenue is Desalus'; your benefit is cheaper water and no liability.
Does it really achieve full zero liquid discharge?
Yes. There is no liquid reject leaving the site — no brine, no concentrate, no outfall. Over 99% of the water is recovered and the salts are recovered as product, satisfying ZLD mandates cleanly.
Will it work on my effluent?
Send Desalus a full-panel effluent quality and volume report through the contact form. You'll receive a site-specific model of recovery, fertilizer yield, avoided thermal cost and payback — before any commitment. It's built for inland brackish effluent at 5,000–50,000 mg/L TDS.
