Industrial rooftop cooling towers with a Nona RECOVER unit installed alongside the piping

Don't let cooling water cap your data center's growth.

NONA RECOVER treats the liquid blowdown your cooling tower would send to drain. Its MIT-patented Ion Concentration Polarization (ICP) process returns treated water to the loop without replacing the tower. We size recovery from your measured flow and water chemistry.

01

Easy to retrofit

A modular retrofit for an existing cooling tower. Confirm piping, controls, and the installation schedule at the site.

02

Modular

Units can be configured to treat a site-specific blowdown flow. Nona's RECOVER technical sheet gives a nominal 10 GPM feed rate for a unit.

03

Built tough

Developed from Nona's seawater work for mineral-rich cooling tower blowdown. Feed chemistry still determines treatment fit.

04

Energy efficient

The electric-field process runs at low pressure. Energy use varies with feed conductivity and the required return-water quality.

05

High recovery

Designed to return 90% of treated cooling tower blowdown. Compare actual water chemistry and concentrate handling before selecting a recovery system.

Estimate what RECOVER saves your site.

Screen potential blowdown return and water and sewer charges avoided. This estimate uses assumed duty and recovery, not measured site flow or net operating cost.

Your Cooling Tower

Cooling Tower Size (TR)The total cooling load of your facility, measured in nominal tons of refrigeration (TR). 1 ton ≈ 12,000 BTU/hr.5,000 TR
Current CoC for OperationHow many times minerals concentrate in the circulating water before blowdown. Higher CoC = less blowdown, but harder water. Typical range: 2–5.4
Water + Sewer Cost ($/kgal)Combined makeup water and sewer discharge cost per thousand gallons (kgal). Check your utility bills for local rates.$20.00 / 1,000 gal

Assumes 60% annual operation duty (approx. 5,256 hrs/yr).

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.

Request a review of these assumptions

Our team can ask for measured blowdown and water chemistry before estimating site savings.

Screening estimate only. Assumes 60% annual wet operation and 90% treatment recovery of modeled blowdown. Charges avoided are gross water and sewer charges, not net OpEx; they exclude unit energy, maintenance, and capital costs. Confirm measured flow, water chemistry, rates, and wet hours before using a site savings figure.

Not reverse osmosisA different path for the water

Reverse osmosis pushes water through a filtration membrane. ICP uses ion-selective membranes and an electric field while bulk water flows through a low-pressure channel. Both approaches need a site-specific chemistry review.

Water can become a hard limit on data center growth.

Water availability, infrastructure, and operating conditions vary by site. Transparent water accounting helps developers, utilities, and communities evaluate demand, discharge, and practical reduction options without relying on one national average.

Desalination science aimed at AI's water waste.

Nona Technologies applies cutting-edge desalination science to cooling water recycling. Spun out of MIT, our patented Ion Concentration Polarization process was built to turn seawater into drinking water — now it closes the loop on industrial cooling water, recovering what facilities would otherwise pour down the drain.

What is data center cooling water recovery?

Cooling water recovery treats liquid blowdown so it can return to the cooling loop instead of being discharged. NONA RECOVER continuously demineralizes that water on site using Ion Concentration Polarization (ICP), an MIT-patented alternative to reverse osmosis.
