This filtration system is designed to effectively remove iron and manganese from ground water, ensuring a clean and potable water supply for residential or industrial needs.
Groundwater often contains high levels of iron and manganese. The Manganese Sand Filter acts as a strong antioxidant, oxidizing ferrous ions to ensure purified water for consumption.
The system utilizes aeration or oxidizing agents to oxidize iron and manganese ions. As water flows through the manganese sand filter, these ions undergo biochemical and physical adsorption, causing them to precipitate. This process also utilizes ammonia removal through bacterial metabolism.
| Iron oxide: Air: 4Fe2 + +3 O2 +6 H2O = 4Fe (OH) 3 ↓ |
| Manganese sand MnO Mn2O7 + Fe2 + + O2 + 6 H2O = 3MnO2 +4 Fe (OH) 3 ↓ |
| Manganese oxide: Mn2 + + O2 = MnO2 ↓ |
