Laboratory measurements on magnetic water treatment device

A short review of magnetic water treatment (MWT) devices with permanent magnets is given. In the paper, the authors present a model of electromagnetic devices with AC electrical input from 40 to 110 W and radial symmetric water flow from 10 to 400 L/min. Electromagnetic properties of the laboratory model EM I are presented and MWT efficiency is discussed. Comparison for the radial magnetic field of a solenoid in air and a solenoid in the device shows that for the used material with magnetization properties, the geometrical construction of tested MWT model is not the best. The next step will be the minimization of the magnetic resistance through the water flow by optimization of the housing geometry.
