The secondary marketplace for used reverse-osmosis plants.
Inland brackish-water operators who switch to the Desalus zero-waste service often retire good RO plants years before end of life. UsedRO is where that proven capacity finds a second home — with buyers in seawater and high-recovery applications who genuinely need RO.

How it works
From listing to offtake in four moves
UsedRO is brokered end-to-end by Desalus, so both buyer and seller deal with one accountable party.
List
Sellers submit plant specs, service history and photos. Desalus verifies and publishes a clean, comparable listing.
Match
Buyers filter by capacity and feed type and inquire. We pair real needs to the right remaining-life asset.
Inspect
An independent inspection confirms membrane condition, run hours and integrity before any money moves.
Offtake
Decommissioning, logistics and recommissioning are coordinated. Seller recovers capital; buyer gets capacity fast.
Why these plants come available
Good RO plants retire early when inland sites switch to Desalus.
Conventional RO was built for the sea. Inland — at 5,000–50,000 mg/L TDS — every liter it can't recover becomes brine to pond, haul or inject, at rising cost and regulatory risk. When those operators move to the Desalus zero-waste service, their RO plant still has years of useful life. Rather than scrap it, they recover capital by selling it here.
- Desalus economics: Desalus funds, builds, owns and operates the treatment — you pay only for clean water at an attractive rate per 1,000 gallons. Desalus recovers and sells the farm-grade fertilizer, which is how it keeps your water price low.
- Environmental win: no evaporation ponds, no disposal liability, and a working asset redeployed instead of landfilled.
- Your gain as a buyer: proven, well-maintained RO at a fraction of new-build capex and lead time — ideal where Desalus isn't a fit, like seawater desalination.
The two-sided value
One switch. Two winners.
Seller
Recovers stranded capital from an RO plant they no longer need — and eliminates brine for good with Desalus.
Buyer
Acquires vetted, remaining-life RO capacity for seawater or high-recovery duty, faster and cheaper than new.
Where Desalus fits, waste disappears. Where it doesn't, the RO still serves someone who needs it.
Sellers & inland water stewards
Switch to Desalus — and recover the value in your RO assets.
If you treat inland brackish water (5,000–50,000 mg/L TDS), send Desalus a full-panel water quality and volume report. You'll get a site-specific model of recovery, your attractive clean-water rate per 1,000 gallons and the capital and disposal costs you avoid — plus a path to list your freed-up RO plant on UsedRO and recover capital.
No obligation. The water report drives the switch model; listing is handled by the same Desalus team.
- Your attractive clean-water rate per 1,000 gallons — zero capital outlay, Desalus funds, builds & operates it all
- Zero brine, zero ponds, zero disposal liability after the switch
- Capital recovered from RO plants you no longer need
- One Desalus team handles the switch and the listing end-to-end
Buyers
Need RO capacity? Acquire proven plants for less.
Tell Desalus your required capacity, feed type and TDS range. We'll match you to a vetted remaining-life plant, arrange independent inspection and coordinate offtake. Mention "UsedRO inquiry" so it reaches the right desk.
Questions
What buyers and sellers ask first
Why are good RO plants for sale at all?
Because inland operators who switch to the Desalus zero-waste service no longer need their reverse-osmosis plant — yet it often has years of useful life. Conventional RO leaves brine to pond, haul or inject inland, while Desalus recovers over 99% of the water with zero brine and turns dissolved salts into farm-grade fertilizer. Rather than scrap a working asset, sellers recover capital by listing it on UsedRO.
How are listings vetted?
Each plant comes with documented service history, run hours and membrane configuration. Before any sale completes, Desalus coordinates an independent inspection to confirm membrane condition, integrity and remaining life — so buyers acquire capacity they can trust.
I need RO — is this for me even if Desalus isn't?
Yes. UsedRO exists precisely for buyers where Desalus isn't the right fit — for example seawater desalination or other high-recovery applications. You get vetted, remaining-life RO at a fraction of new-build capex and lead time. Send a buyer inquiry with your capacity, feed type and TDS range.
How do I list my plant or get a switch model?
Send Desalus a full-panel water quality and volume report through the contact form. Desalus capitalizes, builds, owns and operates the treatment; you pay only for clean water at an attractive rate per 1,000 gallons, and Desalus recovers and sells the resulting fertilizer to keep that rate low. You'll receive a site-specific model of recovery, your clean-water rate and the capital and disposal costs you avoid — and the same team will list your freed-up RO plant on UsedRO so you recover capital.
