FISH SLUDGE TREATMENT


Fjell Technology Group recycles sludge from aquaculture facilities and municipal wastewater plants. 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 small smolt farms, to post-smolt farms, land-based ongrowing fish plants, and semi-closed and closed ongrowing farms in the sea.

The TMD Fishsludge Recovery System (FRS) can dry sludge from 0.1 per cent Dry Matter (DM) and up to 99 per cent DM.

We use award-winning technology without the use of chemical polymer for the purification stage of wastewater from drum filter and possibly biofilter (electro coagulation). Wastewater-sludge from the purification stage is then dewatered and dried with tested and reliable technology. .

Although Fish sludge can be very demanding to dry, this is not a problem for the TMD mill as it is especially 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 Fishsludge system is also not sensitive to plant changes in biomass, waterflow, or in the composition of the sludge.

The dried sludge is perfect as a part ingredient in the production of agrigultural fertilizers, as it is rich in nitrogen and phosphorus. Fjell's technology contributes to a circular economy by recycling vital nutrients from the wastewater.

The solution helps fish farmers and municipal waste plants minimize the need for waste management and transport, which cuts both costs and emissions from production and treatment processes.

The plant requires minimal maintenance and supervision and delivers stable hygienized and stabilized sludge.

TMD is offered with Thermtech (technology owner) and partner - electro flocculation is offered with Power & Water as partner.
