Title:
FLOCCULATION AND MAGNETIC SEPARATION DEVICE, SHIP EQUIPPED THEREWITH, AND METHOD OF OPERATING SAME
Document Type and Number:
WIPO Patent Application WO/2021/095383
Kind Code:
A1
Abstract:
[Problem] With conventional flocculation and magnetic separation devices, it has been impossible to produce smaller-scale devices, because the floc is easily destroyed. There also has not been any ballast water treatment device capable of simultaneously removing plastic or microplastics floating in the ocean. Moreover, there has been no ship or method of operating same for solving the pollution problems caused by plastics and microplastics floating in the ocean. [Solution] By providing a magnetic drum that rotates in a direction which is the reverse of the flow of a fluid containing floc, and by changing a flow path by around 180° immediately prior to contact with the magnetic drum, it becomes possible to achieve a smaller-scale magnetic drum that is able to remove the floc without breaking same and that needs less surface area. Combining a device for destroying/recovering floating plastics with the smaller-scale flocculation and magnetic separation device makes it possible to simultaneously remove plastics and microplastics floating in the ocean. With respect to the planned route information of a ship, giving consideration to marine plastic conditions would enable ships to remove plastics and also microplastics floating in the ocean.
