The principles of physical effects of the magnetic field on H 2 O molecules as well as the parameters of physico-chemical processes occurring in water and the behavior of the dissolved in water scaling salts subjected to the magnetic treatment are discussed. It is demonstrated that the effect of the magnetic field on water is a complex multifactorial phenomenon resulted in changes of the structure of hydrated ions as well as the physico-chemical properties and behavior of dissolved inorganic salts, changes in the rate of electrochemical coagulation and aggregate stability (clumping and consolidation), formation of multiple nucleation sites on the particles of fine dispersed precipitate consisting of crystals of substantially uniform size. There are also submitted data on constructive features of magnetohydrodynamic cell based on the permanent magnets and electromagnets (solenoids) as hydro magnetic systems (HMS), magnetic transducers (MT) and magnetic activators (MA) of water. It was estimated the efficiency of using the various magnetic water treatment devices in water treatment technologies. Key words: magnetic field; magnetic water treatment; magnetohydrodynamic cell; scaling salts. Introduction As is known, the effect of magnetic field on water bears a complex and multifactorial character that in the final result affects the structure of water and hydrated ions as well as the physico-chemical properties and behavior of dissolved inorganic salts (Ochkov, 2006). When being applied to water, the magnetic field therein changes the rates of chemical reactions due to the occurrence of competing reactions of dissolution and precipitation of the dissolved salts, facilitates the formation and decomposition of colloidal complexes, and improves electro-coagulation followed by sedimentation and crystallization of scaling salts of Ca 2+ , Mg 2+ , Fe 2+ and Fe 3+ (Klassen, 1978). Hypotheses explaining the mechanism of action of the magnetic field on water are divided into three main
