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.

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.

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.

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.

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.
