The reaction equations for the iron removal stage are as follows: -Fe³⁺ + 3OH⁻ → Fe(OH)₃↓ (reddish-brown precipitate) -Fe²⁺ + 2OH⁻ → Fe(OH)₂↓ (initially white, rapidly oxidizing to green and reddish-brown) The generated iron hydroxide precipitate possesses a large specific surface area and strong adsorption capacity. PTMS MAGNETIC SEPARATOR not only removes iron ions but also co-precipitates other heavy metal ions (copper, zinc, lead, etc.), achieving simultaneous removal of multiple metals.
This process generates complex by-product components that require careful consideration during subsequent treatment. Following sedimentation, the system enters a settling phase. The iron removal process in PTMS MAGNETIC SEPARATOR typically occurs in sedimentation tanks or clarifiers, lasting from 30 minutes to 2 hours depending on suspended solids concentration, temperature, and particle size.
To accelerate sedimentation, flocculants such as polyacrylamide can be added to aggregate fine particles into larger flocs, significantly enhancing the solid-liquid separation efficiency of PTMS MAGNETIC SEPARATOR. Subsequently, the system undergoes solid-liquid separation using equipment like plate and frame filter presses, vacuum filters, or centrifuges. The resulting filtrate becomes preliminarily purified water that can be further refined or reused.
