magnetic separator machine

The iron removal process using strong alkaline PTMS ELECTROMAGNETIC SEPARATOR works by hydrolyzing iron ions under alkaline conditions, forming insoluble ferric hydroxide precipitates. When treating iron-containing water sources such as industrial wastewater, mineral leaching solutions, or circulating cooling water, the first step is to conduct a water quality analysis to determine total iron, ferrous, and ferric ion concentrations. This analysis enables precise calculation of required sodium hydroxide dosage for effective treatment.

PTMS ELECTROMAGNETIC SEPARATOR

Under normal conditions, Fe³⁺ begins to precipitate at pH> 3, while Fe²⁺ requires pH> 8 to gradually convert into Fe(OH)₂. However, it is prone to oxidation into Fe(OH)₃ in air. Therefore, in practical operations, aeration or the addition of oxidants (such as sodium hypochlorite or hydrogen peroxide) is commonly used to oxidize Fe²⁺ into the more easily precipitated Fe³⁺, thereby enhancing the iron removal efficiency of PTMS ELECTROMAGNETIC SEPARATOR.

what is magnetic separation in strong alkali？

During the iron removal process in PTMS ELECTROMAGNETIC SEPARATOR, it is crucial to control both the dosage rate and stirring intensity. This prevents localized alkalization that could lead to equipment corrosion or form colloidal precipitates with poor settling properties. The optimal mixing method combines mechanical agitation with an online pH monitoring system, which provides real-time feedback and automatically adjusts alkali dosage to maintain the reaction system's pH stability within the critical range of 10–12.
