Sludge drying in Smolt Production

Sævareid Fishfarm and Fjell Technology Group

A Story of Growth and Innovation Since 1978

Established in 1978 in the repurposed buildings of a former cardboard factory, Sævareid Smolt has grown into one of Norway’s most respected producers of high-quality smolt. With a legacy rooted in continuous development and innovation, the facility has evolved through gradual expansions and ongoing modernization.

Aquaculture is a relatively young industry, and Sævareid has consistently been at the forefront of its technological advancement. Today, the facility produces 28 million smolt annually, using a combination of flow-through and RAS technology to ensure optimal conditions for fish health and growth.

Fjell Technology Group is proud to be a trusted partner in Sævareid’s journey. Since 2017, we’ve supported the facility with several key solutions:

  • Delivery of a TMD400 drying system for sludge handling, where dewatered sludge from a belt filter is dried and hygienized.
  • Installation of a fully automated big bag system with three stations for safe and efficient storage of dried sludge.
  • Implementation of a heat recovery system that repurposes vapor from the drying process to heat the dewatered sludge.

The dried sludge can be used as feedstock into bio-fertilizer production at IVAR site in Stavanger. Sævareid Smolt Fishfarm exemplifies how tradition, innovation, and sustainability can work together to shape the future of aquaculture. Fjell Technology Group is proud to contribute to their continued success.
