We transform waste into resources in a sustainable way

Water Challenge was created to put an end to contaminated fluid discharges, with zero liquid discharge (ZLD) and responding to water scarcity.

What do we do in Water Challenge?

Water Challenge purifies all types of contaminated fluids in a single process and in a sustainable way, recovering 100% of the water suitable for any use and dry solids that can be recovered.

ASEC Technology

Disruptive and patented process of evaporation and crystallisation in a single physical and continuous process, with low energy consumption <20kWh/m3, without chemicals or consumables.

Solutions

ASEC technology treats any type of fluid with a wide range of pH and conductivity, according to each customer's needs.

Projects

Our plants in operation and our innovation projects prove the effectiveness of our patented technology.

A circular economy process

Social and environmental commitment

Water Challenge meets the environmental challenges of the European Union, the Blue Economy and the Green Deal, and the Sustainable Development Goals (SDGs) of the United Nations.

  • Zero discharge: Recovers pure water from any type of fluid and dissolved or suspended raw materials, complying with the principles of circular economy.
  • Environmentally friendly: No impact on the environment as it does not use chemicals or consumables and does not pollute.
  • Reduces water stress thanks to the 100% purification of water after desalination, or any industrial or sanitation process, it is suitable for reuse in industry (zero water footprint) or irrigation.
  • Lowers the carbon footprint CO2 thanks to energy-efficient zero liquid discharge (ZLD) technology, which can be powered by renewable energy or waste heat. No additional emissions, as transport is eliminated by installing the plant close to the fluid production site.
