AQUA-RNX
AQUA-RNX is a physical pre-treatment solution that acts before reverse osmosis, reducing the salt load of the water and enabling significant energy savings.
It does not replace existing technologies, but rather enhances them—helping to reduce membrane wear, extend system lifespan, optimize overall plant operation, and even capture atmospheric CO₂ during the process—all without the use of chemicals.
What is AQUA-RNX?
AQUA-RNX is a physical pre-treatment solution that acts before reverse osmosis, reducing the salt load of the water and enabling significant energy savings.

Active CO₂ capture during the process
Reduced volume and concentration of brine discharge
Easy integration into existing or new plants, with no major modifications needed
AQUA-RNX – A New Chapter in Desalination
A physical pre-treatment solution designed to enhance existing desalination systems
Developed by RNX Water Systems in collaboration with PROMETE Srl, a spin-off of the National Research Council of Italy (CNR), AQUA-RNX applies an innovative physical process that not only facilitates desalination, but also promotes carbon uptake through a low-energy reaction.
The technology is protected by industrial patent no. 102022000020472.
AQUA-RNX integrates seamlessly into existing infrastructures, improving energy efficiency and environmental performance — without the use of chemical additives.
