Alfa Laval and Hydros Develop Italy's First Zero Liquid Discharge System at Tecnoparco Valbasento
Alfa Laval and Hydros have created Italy's first Zero Liquid Discharge (ZLD) system at Tecnoparco Valbasento, designed to treat highly polluted industrial wastewater while recovering reusable water and solids. The system can recycle up to 98% of the wastewater, producing only a crystallized salt as a byproduct. This initiative aims to enhance water circularity and promote sustainability in industrial processes.

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.
