Salher solutions to reduce the water footprint of artificial intelligence

Behind every AI model lies a complex supply chain that begins with the extraction of critical minerals such as copper and lithium. These processes involve intensive water use, as well as the generation of waste and direct impacts on ecosystems and local communities.

The wastewater generated by the mining industry is typically loaded with heavy metals, sulfates, and extreme acidity (low pH). To treat this type of industrial wastewater, Salher recommends physicochemical processes such as clarification and sedimentation, which remove suspended solids and heavy metals through coagulation and flocculation. Solutions include Dissolved Air Flotation (DAF) systems like VESPA and XCORPIO, as well as neutralization and precipitation systems designed to adjust pH levels and remove dissolved metals.

For projects requiring higher water quality standards, Salher offers advanced treatment technologies such as biological treatment systems, reverse osmosis, nanofiltration, and ion exchange. These solutions are designed to remove salts, dissolved metals, and chemical contaminants, ensuring compliance with strict discharge or reuse requirements.

In addition, Salher develops tailor-made solutions incorporating water recirculation through evaporation and crystallization systems. These advanced processes enable zero liquid discharge (ZLD), allowing water recovery and the generation of dry solid waste. This approach facilitates the reuse of process water and minimizes freshwater extraction.
