Sterner AS

Ever since the early 1990’s our focus has been on water treatment. We know that water is a common resource. It is borrowed from nature. We are obliged to return it in as pure a state as when we removed it from nature. This is Sterner’s main goal.

Delivering water treatment to four markets; aquaculture, municipal, marine and industry, we use several process technologies which we combine to develop sustainable solutions while focusing on clean and safe water.
