Product Overview

LEFILTER manganese sand filters are specially designed for efficient iron and manganese removal from groundwater and industrial process water. Our high-grade manganese dioxide (MnO₂) coated media provides superior oxidation and filtration performance compared to conventional systems.

Key Features & Benefits

✔ High-Purity Media - 85-90% MnO₂ content for maximum oxidation capacity
✔ Multi-Layer Design - Graduated media bed for optimal filtration
✔ Low Maintenance - Backwash efficiency reduces operating costs
✔ Corrosion-Resistant Vessels - FRP or stainless steel options available

Working Principle

Our manganese sand filters operate through a dual mechanism:

  1. Oxidation

    • MnO₂ coating oxidizes dissolved Fe²⁺ and Mn²⁺ to insoluble Fe³⁺ and Mn⁴⁺

  2. Filtration

    • Multi-layer media bed traps oxidized particles

    • Graduated particle size ensures progressive filtration

  3. Regeneration

    • Periodic backwashing removes accumulated particles

    • Potassium permanganate (KMnO₄) can be used for enhanced regeneration
