This paper reviews electromagnetic water treatment, an alternative solution for scale control in industrial water processing, and a model device with solenoid coils inserted into a cylindrical kernel inside a pipe is analyzed for potential application at high water-flow capacity (few hundreds of m3/h). An efficiently strong magnetic field (e.g. with maximum magnetic flux density from 0.1 T to 0.2 T) can be produced using a DC electric supply resulting in total costs at least ten times lower than the expense of the scale-prevention ion exchange.
► A model proper for anti-scale magnetic treatment at high water-flow load is selected.
► A theoretically estimated magnetic field is optimized by the finite-element method.
► This model fulfills the required parameters for efficient scale prevention.
► The expenses with DC supply are at least ten times lower than at ion exchange.
► The electricity expenses at 50 Hz are comparable to chemical anti-fouling methods.
