Sewage treatment plants

Experts in water treatment

Stjernholm holds a key position on the water treatment market at public as well as private sewage treatment plants, in sewage systems and at waterworks throughout the country.

We actively apply the latest knowledge and continuously work to implement new, useful knowledge into our solutions.

Our focus is: The solutions that we offer must hold tangible and measurable benefits to the customers. The investment must pay off – and we typically operate with a payback time of between 2 to 5 years on new investments.

Our knowledge and product range cover the entire spectrum from pre-treatment over the process to sludge processing and various solutions to systems “outside the fence”.
