About Salsnes Filter
Our work is driven by a commitment to advancing solids‑separation technology. Through continuous research, product development, rigorous testing, and strong quality initiatives, we’ve engineered a highly efficient and reliable filtration solution. Our technology maximizes solids separation while significantly reducing capital, operating, maintenance, and land‑related costs.
Our history
Our roots go back to 1991, when we first developed a mechanical filtration system capable of treating water for fish hatcheries in Norway. Prototype systems were also installed to treat primary municipal wastewater. However, we made our market breakthrough in 1998 when Salsnes Filter systems were able to demonstrate that treated primary wastewater could meet European and Norwegian discharge requirements.
In 2002, an important milestone was reached when our production moved to a new facility in Salsnes, Norway. At the same time, we installed successful projects in industrial wastewater treatment facilities including pulp & paper mills, food processing plants, breweries, fish hatcheries and land-based fish farms.

Sustainability at our core
Sustainability isn’t an initiative for us, it’s a principle that guides everything we do. From the way we design our technology to how we operate as a company, we’re driven by the belief that smarter solutions should also be cleaner, more efficient, and better for the planet. Our commitment to environmental responsibility shapes our innovation, our partnerships, and the long‑term value we deliver to communities around the world.
Case studies
Recovering Lost Treatment Capacity
Faced with rising loads, aging infrastructure and limited space, Daphne Utilities rethought primary treatment to boost capacity, stabilize downstream processes and reduce operational strain—all within their existing footprint.
Optimizing Biogas Production with Primary Sludge
To expand capacity and boost renewable energy output, the Saulekilen WWTP reimagined primary treatment, using advanced solids separation to increase biogas production while staying within their existing footprint.
Recovering Resources from Wastewater at Italy’s SMART-Plant
At the Carbonera Water Resource Recovery Facility, advanced primary treatment increased solids capture, improved downstream efficiency and opened new opportunities for energy and nutrient recovery.
Handling Variations in Incoming Flow
In the heart of a UNESCO World Heritage fjord, the Geiranger WWTP upgraded primary treatment to handle extreme seasonal loads and protect one of Norway’s most iconic natural environments.
Primary Treatment & Cellulose Recovery
By integrating advanced primary treatment, the Carbonera WRRF increased solids capture and recovered high‑value cellulose, improving plant performance while supporting a circular, resource‑driven approach to wastewater treatment.
