Tecnoparco Valbasentoにおける水循環の加速 ― ZLDシステムによる操業継続の実現
イタリア・バジリカータ州に位置するTecnoparco Valbasentoは、国内でも有数の水資源に恵まれた地域にあります。しかし近年、気候変動の影響により水不足が発生し、この地域で通常行われている事業活動を継続するには十分な水を確保できない状況に直面しました。 そこで導入されたのが、Zero Liquid Discharge（ZLD）システムです。このシステムにより、水を再生・循環させる新たな水フローが生み出され、Tecnoparco Valbasentoは安定して蒸気を生成できるようになりました。その結果、水資源の制約を受けることなく、すべての事業活動を滞りなく継続することが可能となっています。

Welcome to the ZLD Space-Time Lab
Ever wondered what really happens when bold innovation meets the gritty reality of industrial systems? Meet Patrick—one of Alfa Laval’s ZLD experts and challengers, and a regular voice on this blog. In this opening post, Patrick sets the stage for what this blog is all about: inviting you into the messy, inspiring, and often surprising space where big ideas are tested, stretched, and transformed into real-world solutions. He also shares why he’s still captivated by Zero Liquid Discharge, despite a rocky first run, and explores how the lessons hidden in failure can often pave the way for breakthrough success. Welcome to the ZLD Space-Time Lab: where problems are respected, collaboration is key, and innovation thrives between imagination and reality.
What is Zero Liquid Discharge?
Zero Liquid Discharge (ZLD) is an innovative technology equipped to minimize industrial water waste. It enables a circular flow of water, allowing it to be reused multiple times within the same process. The benefits of using a Zero Liquid Discharge system include reduced water pollution, as it prevents harmful pollutants from being discharged into natural water bodies. It also reduces waste volume, minimizing the amount of waste that needs to be managed and disposed of. Additionally, ZLD systems lower fresh water intake by recycling and reusing wastewater, leading to significant cost savings over time. Furthermore, these systems allow for the recovery of valuable by-products from wastewater, which can be reused or sold.
