The Waternet Datalab team aims to execute projects that are actually implemented. A robust MLOps workflow is essential for this. As part of the Datalab team, we have set up the MLOps workflow and maintain it. This includes an MLFlow model registry, CI/CD templates, and the implementation of code and models into production. We have developed an ML model to minimize nitrous oxide emissions at the wastewater treatment plant. Currently in development is a model to limit the use of iron chloride in the pre-treatment of river water for drinking water production.
