In a conventional flocculation and magnetic separation device, it was not possible to make the device downsized because the flocs are easily broken. In addition, there was no system for the ballast water treatment that is capable of simultaneous removal of plastics and microplastics drifting in the ocean. Furthermore, there were no ships and their navigation method capable of solving the pollution problem caused by plastics and microplastics floating in the ocean. By arranging a magnetic drum that rotates in a direction opposite to the flow of a fluid containing flocs and by changing the flow path by about 180 degrees or so immediately before contacting the magnetic drum, the flocs can be removed without breaking. This method can downsize the size of the magnetic drum with the required area reduced. By combining small-sized flocculation and magnetic separation device and a device that breaks and recovers floating plastics, it is possible to remove plastics and microplastics floating in the ocean at the same time. By taking into account the status of marine plastics in the ship's planned route information, it becomes possible to remove plastics and microplastics floating on the ocean by the ship.

A magnetic separator includes a housing defining a product flow path, a drawer moveable between a first position and a second position, a magnet operatively connected to the drawer, the magnet positioned within the product flow path when in the first position and the magnet withdrawn from the flow path when in the second position, and a stripper plate frame attached to the housing. A stripper plate is fixed to the stripper plate frame that conforms with the magnet and through which the magnet passes as the drawer is moved between the first and second positions. An anti-rotation mechanism includes a slot that engages along a length of a shoulder such that. When the anti-rotation mechanism is positioned having the slot over the shoulder, the magnet is prevented from moving from the axially locked position. The shoulder extends beyond an outer surface of the anti-rotation mechanism.

A method of producing an atomized powder includes: an atomizing step of forming magnetic alloy particles from a molten metal by an atomizing method, to obtain a slurry in which the magnetic alloy particles are dispersed in an aqueous dispersion medium; a slurry concentration step of causing magnetic separation means to separate the magnetic alloy particles from the slurry to form a concentrated slurry having the magnetic alloy particles of more than 80% by mass, the magnetic separation means using a rotary drum including a magnetic circuit part fixedly disposed at a position where at least a part of the magnetic circuit part is immersed in the slurry and an outer sleeve capable of rotating outside the magnetic circuit part; and a drying step of causing drying means using an air flow dryer to dry the concentrated slurry to form a magnetic alloy powder.
