Abstract
A filtrating method for removing suspended solids from a liquid by passing the liquid through a layer of filter medium in a magnetic field, the filter medium layer comprising a collection of organic fibers and ferromagnetic metal fibers. Usual suspended solids and relatively large magnetic suspended solids are arrested by the organic fibers, while fine magnetic suspended solids are arrested by the ferromagnetic metal fibers subjected to the action of the magnetic field. The collection of fibers achieves a high filtration efficiency, has outstanding regeneration characteristics, withstands continued use and is therefore very useful as a filter medium.
