ABSTRACT The main problem of widespread introduction of magnetic water treatment (MWT) in the processes of water and wastewater treatment is the lack of modern research aimed at studying the mechanisms of MWT effects, in particular the influence on the physicochemical properties of aqueous solutions. This study explains the effect of MWT taking into account the physical and chemical properties of aqueous solutions due to the presence of the quantum differences in water . All of the MWT effects are related to the change in the physicochemical properties of aqueous solutions. It is due to the presence of two types of water isomers and their libra- tional oscillations. The result of MWT is a violation of the synchronism of para-isomers vibrations, with the sub- sequent destruction of ice-like structures due to the receiving of energy from collisions with other water molecules (ortho-isomers). One of the most important MWT effects includes the change in the nature and speed of the physi- cochemical processes in aqueous solutions by increasing the number of more physically and chemically active ortho-isomers. The MWT parameters specified in the work allow explaining the nature of most MWT effects and require developing the scientific and methodological principles for the implementation of the MWT process and mathematical modeling of the MWT process in the water and wastewater treatment. It can be used in the design of the MWT devices taking into account the constructive and mode parameters of MWT devices.

The shift of the ET rotation radius and consequently a change in the speed (frequency) of its precession are different for neighboring water molecules due to the different orientation with respect to the magnetic induction lines, which causes disturbance of the synchronization and cooperativity of the libration vibrations of the neighboring water molecules.
