摘要： A system for separating particulate from a fluid stream having an inlet solids content, the system comprising: a magnetic dynamic settling vessel comprising at least one magnetic field inside the vessel and/or one magnetized component; at least one inlet for introduction of the fluid stream having a starting solids content; at least one exit for a stream comprising a solids content not greater than the inlet solids content; at least one exit for a fluid stream comprising a solids content not less than the inlet solids content; and a vertical feed conduit extending at least 70% of the distance from the at least one fluid inlet to the at least one exit for a fluid stream comprising a solids content not less than the inlet solids content. A method for separating particulate from a fluid stream having an inlet solids content is also provided.
