“…Their main advantage is the fact that the MF they generate affects the crystallization of CaCO 3 by delaying its precipitation. It also triggers the "memory effect", which means that the anti-scale properties of calcium carbonate in the installation persist for some time from exposure to the magnetic field [29,30]. Another example of the use of MF in water treatment is the use of magnets to increase water saturation with oxygen.…”

Currently, methods of water purification and aqueous solutions leading to effective reduction of introduced chemical compounds into water purification systems have become the subject of research. Physical methods have become an alternative, because by subjecting water and aqueous solutions to UV (ultraviolet) radiation or magnetic fields (MF), either ultrasonic or electric, it is possible to influence the change of structure, which results in changes in the properties of water and aqueous solutions. This paper attempts to verify the influence of a weak magnetic field on the removal of iron and manganese compounds in the filtration process on gravel of 1–2 mm granulation, sand of 0.4–0.8 mm granulation, activated alumina and activated carbon. The conducted research proved that MF has a significant influence on the effectiveness of iron and manganese removal from water in the case of alumina, while in the filtration process through other filter materials the effect of MF was small.

“…Given the complex process of scale formation, including the physical, chemical, biological, and other aspects, the scale inhibition method is divided into many kinds . Calcium carbonate is the main element of the scale; moreover, numerous studies have shown that the magnetic field can change the calcium carbonate crystal shapes to achieve scale inhibition effects . In recent years, electromagnetic scale inhibition technology has received widespread attention due to its low investment, speed, easy usage, environmentally friendliness, and other advantages .…”

The absorbance values of specific configuration solutions under different magnetic treatment conditions are studied using the UV method based on the circulating dynamic simulation experiment platform for the anti‐scaling of electromagnetics. Additionally, the relationship between the absorbance value and solution concentration is determined. Moreover, the nucleation rate of CaCO3 is calculated using the absorbance value. The influence of the specific magnetic field on nucleating rate is analyzed. Subsequently, the magnetic memory effect and time of CO3−2 and water are studied. Results show that the magnetic treatment changes the nucleation rate of CaCO3 and the critical oversaturation of the solution by acting on CO3−2. This treatment also can promote the dissolution of CaCO3 in water by changing the properties of water. These two aspects all exert memory effects; however, their respective memory times are different. Moreover, the results show that the magnetic treatment can reduce the critical oversaturation of the CaCO3 solution and accelerate the nucleation rate. Furthermore, the memory time of the magnetic field acting on CO3−2 and the properties of water are 45 min and 78 h, respectively.
