This paper reports the study of a HGMS (High Gradient Magnetic Separation) process for the treatment of industrial wastewaters that considers an assisted chemical-physical pre-treatment for the removal of heavy metals through the bound with added iron-oxide particulate matter (hematite). The filter is constituted by ferromagnetic stainless steel wool that, in presence of an external magnetic field, provides the necessary magnetic field gradient for withholding the hematite. Experimental activity on a laboratory device has been carried out in order to test the model.
