Through two specific customer case studies, we'll demonstrate the value of Digital Twins in addressing pressing operational challenges. The first study will focus on a municipal wastewater treatment plant (WWTP) in Germany, where the implementation of Digital Twin technology resulted in a 35% reduction in nitrous oxide emissions, a potent greenhouse gas (GHG). The second case, from a <5 MGD WWTP in the Mid-Atlantic region, will show how energy savings were achieved by optimizing aeration setpoints, leading to a 20% power use reduction.
