MAGNETIC DEVICE SIMULATION MODELLING AND OPTIMISATION FOR SCALE CONTROL

The paper presents model devices for magnetic water treatment, optimized for scale control at water capacities up to a few m(3)/h. Different arrangements of permanent magnets were investigated and simulated at different water-flow capacities to yield the proper magnetic field distribution and the required magnetic flux density, using the computational program OPERA 15R1 (Vector Fields Software) with the finite-element method, considering the real 3D-geometry, non-linearity of magnetic properties of construction materials, and the interaction of neighbouring poles.
