The treatment of river and harbour sediments is a major challenge. A variety of substances can contaminate the sedimentation. For this reason, we have developed a holistic solution: The CatFish. Its space-saving construction in a portable 40 ft design makes it easy to assemble. The combination of upstream classifier and proven screening machine technology guarantees success for slurry volumes up to 14 m³/h with a solids capacity up to 10 t/h and a grain size of 10 mm at maximum.
