Skira Wastewater treatment
Fully automated systems for aquaculture effluent and sludge treatment
Proven and complete process solution for efficient separation of dry matter (DM) from water.
Skira by Fjell Technology Group is a customized end-to-end solution for aquaculture effluent and sludge treatment. The process is easy to operate and use as we provide a fully automated system.
Skira WWTP (Wastewater Treatment Plant) can include:
- Polymer and Coagulant Performance system for pre-treatment of WW
- Thickening to 2-8 % DM by belt thickeners or Lamella DAF solutions
- Dewatering up to 25% by Decanter or Screw press solutions
- Drying >90 % DM by our energy-efifcient, patented dryer solutions.
- Release Ready Clean water assurance of reject water by means of biological treatment to achieve even higher BOD and COD removal before discharge
Skira represents clarity, responsibility, and innovation
Skira is the name of our wastewater treatment technology and solutions for aquaculture and fish processing. Derived from Old Norse, Skira means “to purify” or “to make clear”—a perfect reflection of our mission. Purity isn’t just a promise; it’s our standard.
- As a complete Design and EPC (Engineering, Procurement, Construction) specialist, we provide our customer with testing, design and engineering, installation, start-up and commisioning and technical support in operation.
- Skira WWTP (Wastewater Treatment Plant) handles large variability in flow and capacity. We have the expertise, technology and solutions that ensure the most stringent emission level requirements are met.
*BAT-AEL (Best Available Technology Associated Emission Levels) are requirements from the EU regarding emissions.
