Use of magnetic filtration in waste water treatment ... Magnetic separation was performed using the high gradient magnetic separator (Jones), with the separation column of 30 mm in inner diameter and 320 mm in length. The separation column was packed with magnetically susceptible filling. The magnetic field was applied and then the sample was

drinking water treatment filtration is the fundamental step that removes particulate matter. The most common filtration process employs a granular medium of a certain size and depth (Kawamura, 2000). Magnetic separation can substitute and/or improve the main steps of water treatment. Water treatment has generally the steps reported in Figure 1.1.c
