Basic Concepts of Magnetic Water Treatment

Abstract

This review article outlines an overview of new trends and modern approaches for practical implementation of magnetic water treatment to eliminate scaling salts (carbonate, chloride and sulfate salts of Ca 2+ , Mg 2+ , Fe 2+ and Fe 3+ cations) in power heat-exchanger devices and pipe lines. The principles of physical effects of the magnetic field on H2O 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 various magnetic water treatment devices produced by domestic industry, based on the permanent magnets and electromagnets (solenoids), such 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.

Investigation on Magnetic Field Usage for Urban Water Treatment

“…The process of water magnetization completely changes the technological approach to the application of the existing water softening stations using the ion exchanger method [4]. MF technology has great possibilities of application when the water is hard.…”

Influence of magnetic field on barium sulfate incrustation from aqueous solutions

“…When applied a magnetic field of 14000 G, the B×v product results in 14671 G m s –1 . According to Mosin and Ignatov. (2014) B×v values greater than 10000 G m s –1 were necessary to prevent CaCO 3 incrustation during the treatment of boiler water using a magnetic field.…”

“…The Lorentz equation determines the force perceived by a particle or ion in movement (with velocity v ) in a region of space subjected to the action of a magnetic field, B . B × v is a vector product, and therefore depends on the lag angle that exists between the two vectors as defined by Mosin and Ignatov. (2014).…”

Ligand‐free, copper‐catalyzed, one‐pot, three‐component synthesis of novel 1,2,3‐triazole‐linked indoles in magnetized water

“…Pure water, as a polar and associative liquid, can modify its intermolecular bonds in an applied magnetic field, changing to a metastable state but keeping that state for some time . Based on Mosin and Ignatov's theory, the applied magnetic field directly affects the structure of water because of the polarization of water molecules. These molecules are bound together via low‐energy intermolecular Van der Waals forces, dipole–dipole interactions, and hydrogen bonding.…”
