The application prospects of magnetic separation wastewater treatment technology

The magnetic separation wastewater treatment technology is based on the different magnetic properties of different substances (the magnetism of substances can be divided into three types: ferromagnetism, paramagnetism, and diamagnetism, among which ferromagnetic substances can be added as magnetic species to weakly magnetic wastewater for magnetic separation). When magnetic or non-magnetic substances (requiring the addition of magnetic species) in wastewater are in a magnetic field, the substances will inevitably be subjected to forces from the magnetic field. Of course, the suspension in wastewater is not only subject to magnetic field forces, but also to gravity, fluid viscosity, fluid inertia, and intermolecular attraction. As long as the magnetic field we apply is large enough, suspended particles in wastewater can be magnetically separated.

Compared to traditional methods of treating wastewater, electrolysis, chemical precipitation, adsorption, and other methods are used for treatment. Sometimes, chlorine gas is also added for disinfection in tap water. Whether using chemical or biological methods, problems such as high costs or incomplete purification may arise. Magnetic separation wastewater treatment is an efficient, energy-saving and environmentally friendly wastewater treatment method.
