Our disruptive, patented technology enables the intelligent use of contaminated water

It offers multiple applications with positive benefits for the environment and society.

A single process

A single, continuous physical process of evaporation and crystallization, without chemicals or consumables and with low energy consumption <20kWh/m³.

It is carried out in 6 steps:

The fluid enters the preheated system
It is introduced at sonic speed into the evaporation chamber
Flash evaporation occurs and the solids precipitate by gravity
The steam produced is compressed and fed back into the system
The condensed steam finishes drying the concentrate, obtaining dry solids
The condensed water preheats the input fluid (step 1)

Two by-products of the treatment

Water suitable for all uses
- Purified 5-250µS/cm
- Suitable for human consumption
- Suitable for industrial use, irrigation or H₂V

Dry solids: <15%
- Valuable as fertilisers or raw materials (mineral salts, metals, etc.)

Efficient in energy consumption <20kWh/m³

Plant with a design adaptable to all renewable energies

Energy cost of ~10kWh/m³ with residual heat

Scalable and modular

No flow limit (from 50m³/day or higher than 2,000m³/day)
Installation in squid or containerized (plug & play in container)
Reduced footprint

Automation and remote control

Software developed for each type of fluid
Remote control operations and alarm management
Automated process, corrects variations
