Alfa Laval and Hydros have implemented Italy's first Zero Liquid Discharge (ZLD) system at Tecnoparco Valbasento for treating highly polluted industrial wastewater. The ZLD system recycles approximately 98% of the wastewater, converting it into steam and other industrial uses, while only generating a crystallized salt byproduct.

The project was initiated under a contract awarded by Tecnoparco Valbasento to Hydros, which handled engineering and installation, while Alfa Laval provided the evaporator and decanter centrifuge. The system operates at an efficiency of approximately 9 cubic meters per hour using 2,800 kg/hour of low-pressure steam, marking a significant advancement in sustainable water management in industrial applications.
