Sterner AS introduces NP Drumfilter in Norway

Sterner AS ( is a leading company in water treatment in Norway. Sterner has been working with microscreen filtration since the beginning of the 1990s, with over 900 drumfilters delivered, mainly for the aquaculture business.

The NP Drumfilter is now replacing Sterner’s earlier line of drumfilters, and is being launched in Norway by Sterner’s offices in Ski, Bergen and Leknes.

“Drumfilter technology has not seen any major development in the past 20 years. When Nils-Åke Persson mentioned that he was developing a new drumfilter, we were immediately interested. Our ambition is to be first with new and better solutions,” says the Managing Director of Sterner, Bjarne E. Pettersen.
