An investigation was made about fundamental characteristic and operational performance of “High Gradient Magnetic Filter” (HGMF).After experiment of changing magnetic field, flow velocity, wire diameter, packing density and viscosity it was confirmed that effects of these factors upon initial removal ratio and filter loading capacity follow certain indexes respectively.Removal performance of waste water could be grasped to some degree by considering magnetization of particle and particle size in addition to the above written factors.On the other hand, there were found various merits of this filter.(1) Ultra high speed filtering is possible and installation area can be reduced.(2) Wide application from low up to high concentration is possible.(3) Running cost is cheap.(4) Back washing time is short and volume of back wash water can be reduced.(5) Removal of non-magnetic particles is also possible by execution of pre-treatment.
