WATER INNOVATION SUMMIT 2023 | Sessione 5-Sudati B

This document describes a project between Iren, an Italian utility company, and Kando, an Israeli technology company. Iren was experiencing high organic pollutant loads at its Valpolcevera wastewater treatment plant that were impacting operations. With Kando's monitoring technology, Iren was able to identify four local industries as the sources of the pollution. Iren then worked with the industries to create corrective plans, resulting in reduced pollution discharges, improved wastewater treatment plant processes, and estimated energy cost savings of 120,000-140,000 euros annually for the plant. The collaboration helped enforce regulations and change factory behaviors to reduce pollution levels in the area.

The utility wanted to manage and find the sources of organic pollutants which impacting Valpolcevera WWTP, including sludge quality, sewage network and effects on the environment
