FISH FARMING - SLUDGE TREATMENT

SLUDGE TREATMENT FOR AQUACULTURE

INTRODUCTION
Norway is the country that produces the most salmon in the world and exports to all parts of the world, much of the salmon production takes place along the Norwegian fjords also on land, mainly
the challenge in the industry is economic growth coupled with environmental responsibility, Norditec helps companies
one with finding solutions for sludge management.
We work with experts in particle separation, sludge treatment and drying.

MANAGEMENT OF WATER CAPACITY AT SLUDGE TANKS
– Dry matter (TS) and water content: 0.01 to 1 %.
- The mud is not stable, a lot of variation.
- Large investment for sludge handling, storage and disposal.
- The biological activity of sludge creates odors and bacteria.
– Sanitization.
- What do we do with the sludge?

SOLUTION AND PROCESS DESCRIPTION
SDP

solutions has been developed for the dewatering and drying of sludge in land-based breeding facilities, the system starts with pre-mechanical filtration of particles smaller than 1 mm, removal of fiber to simplify mechanical processing.
Norditec produces and adapts solutions for the food industry and aquaculture i
cooperation with European manufacturers of equipment, we have tested all the steps in the process for the SDP solution.
- These techniques can be adapted to biological and chemical treatment plants.
– RAS – recirculating aquaculture systems.

THE PROCESS SOLUTION CONSISTS OF SEVERAL STEPS FOR DEWATERING, THE PROJECT
DEVELOPED WITH OPERATIONAL STAFF TO INCREASE EFFICIENCY IN THE FACILITY.
– 2-4 steps in the dewatering process.
– Buffer between each processing step, monitoring and automation.
- The system is reliable and continuous.
- A flow aggregate can be recommended in case of peak flow.
– Thickening system for processing high percentage dry matter.
- The process is always developed with the help of internal technical staff in the customer's company.
- We offer training for
