Technical Principle

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. 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 Ca2+, Mg2+, Fe2+ and Fe3+.

Based on 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, we developed Novel Electro-Magnetic(NEM) Membrane Fouling Control System for membrane system (RO/NF/UF) on descaling and sterilization. 

Different from traditional treatment with chemical substances, NEM is an electrical device which uses physical method to control membrane fouling. NEM is composed of electro-magnetic coils and program controlled host.

See below picture.

We have below basic models according to water sources and membrane types.

Applications

Novel Electro-Magnetic(NEM) Membrane Fouling Control System can be used in any type of membrane system, such as RO(Reverse Osmosis), NF(Nano Filtration), UF(Ultra Filtration)

Typical industries：Desalination, Landfill leachate, Thermal power plant, Paper making, Food and drink, Chemical industry, Electronics, Pharmaceutical industry etc.
