The ClearFlow project, coordinated by Water Challenge, aims to validate a hybrid solution for treating contaminated water from mining. Over a period of 30 months, this international project will develop a system that combines electrocoagulation with patented ASEC technology to achieve advanced, efficient purification and generate recoverable waste.
The initiative is co-financed by the Eureka/Eurostars program, with support from the European Union, and involves Hofitech (Slovakia), a technology partner specializing in metal separation and electrochemical process optimization.
The system has been designed to obtain high-purity water, free of dissolved metals and salts, along with dry solid waste that can be commercially exploited, especially for its content of heavy metals, rare earths, and other strategic elements.
The project is structured in three phases: characterization of mining effluents, integration of technologies, and validation of the prototype in a real industrial environment in collaboration with the Slovak partner.
ClearFlow represents a step toward a circular economy in the mining sector by preventing polluting discharges, reducing waste volume, and recovering both water and valuable materials contained in these effluents.
