Prevention of pipe walls from scale deposition by using Magnetic Field Treatment

A home-made magnetic device was built with permanent magnets for treating scaling waters. Its efficiency was evaluated by measuring the remaining ionic calcium at the output of the device by means of an ion selective electrode. The scaling power of the treated water was estimated through an electrochemical scaling test. Chroamperometric curves and chronoelectrogravimetric curves were plotted to obtain the scaling time and the nucleation time of the scale deposition. The variation of the efficiency of the magnetic treatment was studied when the length of treatment, the flow velocity of the scaling water in the device, the material of the pipe where the scaling water flowed were changed. Magnetic water treatment does not change the chemistry of water but it alters the structure of water. Lorentz force is exerted on water ions the redirection of particles increases the frequency of collision between ions and opposite sides combining to form a mineral precipitate or in soluble compound scale deposits by natural waters often lead to numerous technical and economic problems in industrial plants and domestic equipment by blocking the flow of water in pipes or limiting heat transfer in heat exchange.
