In coal washing plants, aluminum sulfate is primarily used for water treatment during the coal washing process.
Main Functions
- Flocculant: Aluminum sulfate acts as a flocculant, causing fine coal slurry particles in the wastewater to aggregate into larger flocs, facilitating sedimentation or filtration, thereby separating the coal slurry from the water.
- Water Purification: Through flocculation, aluminum sulfate effectively removes suspended solids and some organic matter from the wastewater, improving water quality for recycling or discharge.
Specific Usage
- Dissolution: Dissolve aluminum sulfate in water in a specific ratio to prepare a solution.
- Dosing: Add the solution to the coal washing wastewater, adjusting the dosage based on the turbidity of the wastewater and treatment requirements.
- Mixing: Ensure uniform dispersion of aluminum sulfate through stirring or pumping to promote flocculation.
- Sedimentation or Filtration: Separate the flocculated coal slurry using sedimentation or filtration equipment, while the clarified water is recycled or discharged.
Content Requirements
The required content of aluminum sulfate varies depending on factors such as the scale of the coal washing plant and the turbidity of the wastewater. Generally:
- Industrial-grade aluminum sulfate: Content ranges between 15%-17%.
- Refined aluminum sulfate: Content can exceed 17.5%.
The specific dosage should be determined through experiments to achieve optimal treatment results.
Precautions
- Safe Operation: Aluminum sulfate is corrosive, so protective equipment must be worn during handling.
- Storage: It should be stored in a dry, well-ventilated area to avoid moisture absorption.
- Environmental Protection: Treated wastewater must comply with discharge standards to prevent secondary pollution.
By using aluminum sulfate properly, coal washing plants can significantly improve wastewater treatment efficiency and reduce environmental pollution.
