Water Challenge unveils its first pilot plant at the Port of Huelva for zero-discharge dredging treatment

Water Challenge has officially presented its first pilot plant for the treatment of contaminated fluids at the Port of Huelva, marking a key milestone after years of technological development. Located at the Muelle Ingeniero Juan Gonzalo, the plant is the first of its kind capable of recovering 100% of the water from dredging and port waters, with zero liquid discharge and very low energy consumption.

Based on ASEC (Adiabatic Sonic Evaporation & Crystallization) technology, the plant separates purified water and dry solids with commercial potential, without using chemicals or consumables. The system operates below 20 kWh/m³ and has been validated by CSIC and the University of Seville. Its modular container-based design allows for flexible deployment in industrial or port environments.

During the launch event, which welcomed more than 120 guests, Water Challenge CEO Susana García emphasized the strategic importance of the milestone:

"This pilot plant is a tangible example of how technological innovation can deliver sustainable and efficient solutions in key industries. We envision a future where industry is both competitive and clean."

The President of the Port of Huelva, Alberto Santana, highlighted the pioneering nature of the initiative:

"This plant offers an effective and sustainable way to separate water from solids. It’s another step in our commitment to sustainability, improving the management of dredged materials and stormwater."

The event also included representatives from science, government and industry. Milagros Romero, Mayor of Palos de la Frontera, stressed the project’s significance for water management and the region’s sustainable development.

This project has been co-funded by the European Commission through the EIC Accelerator programme, with a maximum investment of €3.5 million.
