Common contaminants

Here you’ll find an overview of the most common types of contaminants we encounter in our projects.

Those of us working with water treatment often see the same types of contaminants — but in different forms and contexts. They may originate from water flows at construction sites, industrial areas, or hard surfaces, and need to be addressed before the water can be discharged. On this page, we present information about some of the contaminants we come across most often. Here you can learn more about how they arise, why they are problematic, and which methods are used to manage them.

The purpose is to provide a clear and consolidated picture of the contaminants we at Swedish Hydro Solutions most frequently encounter in our work. Our aim is to offer a place where you can explore these topics in more depth and gain a clearer understanding of what water treatment actually involves in practice.
