The Application of High–Gradient Magnetic Separation to Water Treatment by Means of Chemically Precipitated Magnetite

Conditions of high–gradient magnetic separation (HGMS) of chemically precipitated magnetite, prepared from a waste material of the titanium white production were studied. The magnetite was used as a sorption material for the treatment of water from the Vltava River. Detailed experimental research resulted in a proposal for a technology of water treatment, schematic description of which is presented. The results of HGMS of chemically precipitated magnetite together with those of water treatment are discussed.
