Permanganate Water Treatment

Permanganate (MnO₄) is widely used in water treatment for its strong oxidizing properties, helping to remove contaminants and improve water quality.  Permanganate is provided in two forms, potassium permanganate as a solid particle (98%) and sodium permanganate as a liquid solution (40%).  Each works identically depending on the method of application.

 

1. Oxidation of Contaminants

  • Iron (Fe²⁺) & Manganese (Mn²⁺) Removal:
    • Oxidizes soluble iron and manganese into insoluble particles, which can then be filtered out.
  • Hydrogen Sulfide (H₂S) Removal:
    • Reacts with hydrogen sulfide to eliminate its characteristic “rotten egg” smell.
  • Organic Matter & Color Reduction:
    • Breaks down organic compounds, reducing color and improving taste.
  • Algae & Biofilm Control:
    • Helps control algae growth in reservoirs and water systems.
  • Disinfection Aid:
    • Can help reduce bacterial growth, but it is not a standalone disinfectant like chlorine.

 

2. Application Methods

  • Pre-Treatment in Water Plants:
    • Added before filtration to oxidize iron, manganese, and sulfides.
  • Well Water Treatment:
    • Used in conjunction with filtration to remove natural contaminants.
  • Wastewater Treatment:
    • Helps control odors and break down pollutants before discharge.

 

3. Considerations & Safety

  • Proper Dosing is Essential: Overdosing can lead to pink or purple water due to residual permanganate.
  • Residuals Must Be Removed: Requires filtration to remove oxidized particles.
  • Handling Precautions: A strong oxidizer that can stain and be harmful in high concentrations.
