**Overview of Groundwater Treatment System:**
Most groundwater contains high levels of iron and manganese, which require efficient filtration systems to ensure clean and safe water. Our company has developed an energy-efficient water treatment system that integrates multiple functions into one unit, reducing complexity and operational costs.
**Key Features of the System:**
1. **Aeration Unit:** This system eliminates the need for aeration ponds or towers, as it only requires a small amount of air to oxidize Fe²⺠and Mn²âº. This reduces the use of chemicals and lowers overall operating costs.
2. **Oxidation and Separation Chamber:** The main part of the device includes a strong oxidizing reaction chamber, which combines with a suspended filter pool in a single unit. This unique design ensures effective separation of impurities.
3. **Filter Unit with Internal Backwash:** The filter is equipped with an internal backwashing mechanism, eliminating the need for additional pumps or backwash tanks. This not only saves space but also reduces engineering investment.
4. **High-Pressure Backwashing:** The pressure filter provides even and thorough cleaning of the filter layer, preventing dead zones and extending the lifespan of the filter.
5. **Direct Connection to Water Supply Network:** The system can be directly connected to the user’s water supply network, eliminating the need for clear water tanks and two pumping stations. This minimizes equipment investment and prevents secondary pollution.
**Application & Working Principle:**
This groundwater filtration system is primarily used in high-speed rail areas, industrial demineralized water systems, and saline pretreatment applications. It utilizes the principle of aeration oxidation catalysis by manganese sand, adsorption, and filtration to remove iron and manganese from water.
The oxidation reactions are as follows:
- **Iron Oxidation:**
4Fe²⺠+ 3O₂ + 6H₂O → 4Fe(OH)₃↓
- **Manganese Sand Reaction:**
MnO₂·H₂O + Fe²⺠+ 2O₂ + 6H₂O → 3MnO₂ + 4Fe(OH)₃↓
- **Manganese Oxidation:**
Mn²⺠+ O₂ → MnO₂↓
- **Adsorption Process:**
Mn²⺠+ MnO₂·Hâ‚‚O → MnO₂·MnOHâ‚‚O + 2Hâº
