RECOVER

Evaporative cooling is the most water-efficient option.

NONA RECOVER is a cooling water recovery system that lets data centers keep evaporative cooling and stop dumping water. It eliminates 90% of wasted water on site with an MIT-patented alternative to reverse osmosis.

Cooling a data center takes an enormous amount of water.

1,150,000 tons

Water a 50 MW data center's cooling system consumes every year, about 300 million gallons.

Air cooling trades that water for significantly more electricity to reject the same heat. Liquid cooling is where new data centers are heading, but most facilities today still run evaporative towers, and that blowdown is still going down the drain.

    Modular tower retrofit

    A skid-mounted unit designed to connect to the cooling tower blowdown line. Tie-in requirements and installation schedule depend on the site.

  2. 02

    Recover liquid blowdown

    RECOVER is designed to return 90% of treated cooling tower blowdown to the loop. Evaporation and other site water uses are separate.

  3. 03

    Keep the cooling design

    RECOVER treats blowdown alongside a cooling tower. For hybrid sites, wet-mode duty determines how much blowdown is available. Confirm controls and tie-ins with the site team.

Nona RECOVER uses ICP technology.

ICP uses an electric field and ion-selective membranes to separate dissolved ions while bulk water moves through a low-pressure flow channel. Unlike reverse osmosis, it does not force bulk water through a filtration membrane. Fit depends on blowdown chemistry, pretreatment, and the required return-water quality.

How does ICP compare?

For cooling tower blowdown, RECOVER is designed to return 90% of the treated liquid stream to the loop. The September 2026 technical sheet specifies a 5–30 PSI operating range; system energy and the practical recovery rate depend on feed conductivity and treatment targets. Compare site chemistry, pretreatment, concentrate handling, and operating cost before selecting ICP or reverse osmosis.

Not a lab concept. Proven where it counts.

RECOVER isn't a benchtop prototype. It's hardware that has been demonstrated at a renewable power generation site, with recovery rates that are measured, not modeled.

Massachusetts Institute of Technology

MIT-patented ICP

ICP, Ion Concentration Polarization, was invented and patented at MIT, then engineered into deployable recovery hardware by the Nona team.

U.S. Army

Backed by the U.S. Army

The U.S. Army funded the development of ICP for field water production, where reliability and low maintenance are non-negotiable.

Start with your cooling tower size.

RECOVER is designed for operating evaporative cooling towers, including the wet side of a hybrid system when it uses a tower. Enter one scale input for a first estimate, then confirm wet-mode duty, measured blowdown, and chemistry in a technical review.

Screening figures only. Charges avoided exclude RECOVER energy, maintenance, and capital costs. Confirm tower flow, chemistry, and wet operating hours before using these as site savings.

Site recovery assessment

Move from product fit to a site-specific review.

Share the project stage and what you know today. Nona's technical team will review fit, identify missing inputs, and recommend the next engineering step.

A screening review is not a final design. Actual results depend on cooling load, water chemistry, operating duty, climate, and local rates.
