Influence of magnetic field on calcium carbonate precipitation Original Research Article

Effect of permanent magnetic field with north and south faces facing each other (0.16 T) on calcium carbonate precipitation type (homogeneous and heterogeneous) and solubility were investigated in different conditions of calcium carbonate water concentration, treatment-pH and water flow rate in the magnetic field. Treated water was exposed to a scaling test by degasifying dissolved CO2 in water. It was found that magnetic treatment increases the total amount of precipitate and favours the homogeneous nucleation depending on water treatment-pH, water flow rate and the residence time.
