Fjell Technology Group offers a complete range of wastewater treatment solutions

The sludge is used as an additive in fertiliser or other agricultural products.

Fjell Technology Group has a unique combination of long experience and high competence, and is a leader in research and development in the industry. We can supply equipment in full range from hatcheries, to smolt farms , to post-smolt farms, to land-based ongrowing fish plants and semi-closed and closed ongrowing fish farms in the sea.

Fjell Technology Group offer 3 main types of solutions for treatment of aquaculture wastewater:

1. Fjell P&W ECO Capture System: environmentally friendly solution with high capture rate.

Award-winning technology without the use of chemicals or polymer for structuring the wastewater. Combined with the best separation and dewatering technology in the market.

2. High Capture Separation System: highest possible capture rate

Complete automated system for structuring the wastewater, separation (thickening) and dewatering with capture rate as high as 90-95%. Brings wastewater with dry matter content (DM) of about 0,1%DM up to above 20% DM.

3. Low-Cost Capture System: low investment cost and moderate capture rate

Combining well proved technology of bandfilters and decanter sentrifuges. This system offers high hydraulic treatment capacity combined with acceptable capture rate, and low investment costs.

The FTG Fishsludge Recycling System (FRS) system can treat wastewater with DM below 0,1% (1000 mg/liter) and through steps of wastewater structuring, thickening, dewatering and drying convert it to dry fine-corned stabilised slugde.

Fish sludge is very demanding to dry but the TMD hammer mill is specifically adapted to this challenging, fiberless material and its high fat content. Particularly the glue phase can be a problem, however the patented TMD mill is robust and resistant.

The dried sludge is repurposed as an additive for producing fertilizer, or in other agricultural products that rely on nutrients such as nitrogen and phosphorus. Fjell's technology contributes to a circular economy by recycling heavy metals and nutrients from sludge and wastewater.
