Polymer Performance System

Strong flocc formation that eases separation, thickening and dewatering.

We offer a proven and complete solution for flocs formation and stronger separation of particles

Our system includes

Pre-treatment of wastewater by chemicals that agglomerates particles and suspended solids into flocs. The flocs are subsequently removed in a physical process.
Provides optimal mixing, dosage, and reaction time of coagulants and/or polymer into the process.
Fully automated system for optimal addition of coagulants and polymers

Why choose Polymer Performance system?

Provides strong flocc formation that improves the separation, thickening and dewatering of sludge.
Handles large variability in flow and capacity.
Automated system eases operation

Skira is our commitment to sustainability

Fjell Polymer Performance System is part of our Skira WWTP.

Derived from Old Norse, Skira means “to purify” or “to make clear”—a perfect reflection of our mission. Skira represents clarity, responsibility, and innovation. Purity isn’t just a promise; it’s our standard.

Advanced sludge treatment at Sævareid Fishfarm

Fjell Technology Group is proud to have supported one of Norway’s leading smolt producers with advanced sludge drying, automated storage system for dried sludge, and energy-saving heat recovery solutions. Sævareid Smolt facility produces 28 million smolt annually.

Wastewater treatment plant in aquaculture

World's first hub for sludge treatment in aquaculture

Explore the first hub in the world to collect and handle sludge from various fish farm plants in the region. The plant is a fully automated sludge drying plant, delivered to Salten Marine Resources in Glomfjord Industry park in 2021.

Next generation Wastewater treatment upgrade at Salten Smolt

Salten Smolt produces and delivers premium-quality smolt to customers across the region. Salten Smolt faced operational challenges with their wastewater treatment system. Through close collaboration and iterative upgrades, Fjell Technology Group and Salten Smolt has built a solution that evolves with the customer’s needs. Design and delivery of an innovative polymer performance system has resulted in better particle aggregation and cleaner water discharge.

Skira Wastewater Treatment solutions

Derived from Old Norse, Skira means “to purify” or “to make clear”—a perfect reflection of our mission. Skira is our complete solution for the treatment of wastewater from fish processing plants, land-based fish farms and fish farm facilities in the sea. We design and deliver complete and fully automated plants for wastewater treatment in aquaculture.

Polymers and coagulants for wastewater treatment

We offer an effective product line that widthstand high salinity for advanced and strong separation in wastewater treatment. Floccera are environmentally friendly water dispersion flocculants (pollymers) and coagulants for wastewater treatment thickening and dewatering

Thickening

The first separation step is thickening of the wastewater whereby the concentration of dry matter (DM) in the wastewater is lifted from up to 0.15 % to 5-10% DM. We offer different thickener designs and a wide range of capacities. Our designs are recognised for high operational stability and long-lasting durability.

Dewatering

Dewatering brings the thickened sludge to 20-25% DM. Dewatering is designed to meet your capacity needs and typically involves a decanter centrifuge, being an energy-efficient and durable dewatering method. Other designs are also available.

Sludge drying

We offer a range of dryers proven for fish sludge applications. For small to medium sized fish farms, our TMD (Thermo Mechanical Dryer) sanitizes and fully dries the sludge by friction heat. For larger capacities, our TD (Turbo Disc) dryer is the most energy efficient option. In Fjell, we have 45 years of experience in full/part drying and utilization of residual raw materials.

Release Ready

Clean water assurance of water effluent and reject water from treatment process (and RAS overflow water) by means of biological treatment to achieve even higher BOD and COD removal before discharge. This final cleaning step is designed to meet stringent environmental regulations and can address remaining solids, nitrogen, phosphorus, total organic carbon (TOC), and other substances as required.
