The electrochemical PTMS MAGNETIC SEPARATOR iron removal method has gained significant attention in recent years for its advantages of requiring no external reagents, maintaining mild reaction conditions, and achieving high automation levels, making it particularly suitable for treating high-salinity wastewater. The core principle involves using a direct current power supply to drive electrode reactions, generating active species with flocculation, oxidation, or reduction capabilities that effectively transform and remove pollutants.
High-salinity solutions inherently possess high conductivity, which facilitates efficient electrical conduction and reduces energy consumption. This makes them particularly suitable for electrochemical PTMS MAGNETIC SEPARATOR iron removal processes. Based on their operational mechanisms, these methods are primarily categorized into two types: the electric coagulation method and the electrodeposition method. In the electric coagulation process, soluble metals (typically iron or aluminum) serve as the anode. When electricity is applied, the anode dissolution occurs, releasing Fe²⁺ or Al³⁺ ions into the solution.
Then, the cathode water is reduced to generate OH⁻, which promotes the hydrolysis of metal ions to form positively charged hydroxide flocs (Fe (OH) ₃ and Al (OH) ₃). These flocs capture colloidal particles and dissolved iron ions in water through adsorption, bridging and netting, and finally realize PTMS MAGNETIC SEPARATOR iron removal separation by precipitation or air flotation.
