Detailed Description

1. Background of Red Mud Treatment in Alumina Production

Red mud is the main solid waste generated during the Bayer process of alumina extraction in alumina production. It contains a large amount of iron, titanium, silicon, and other components and is strongly alkaline (pHvalue can reach10-13). Due to its high water content and fine particles, red mud is difficult to treat. If not properly handled, it will not only affect environmental safety but also cause resource waste. Therefore, efficient dehydration treatment of red mud has become an important part of the alumina industry.

2. Application of Chamber Filter Press in Red Mud Treatment

The chamber filter press is a solid-liquid separation equipment widely used in chemical, metallurgical, and mining industries, especially suitable for filtering slurries with high solid content and high viscosity. Its main features include:

  • High-pressure dehydration: High pressure is applied through the filter plates to make the red mud slurry filter quickly, increasing the solid content of the filter cake.
  • Efficient solid-liquid separation: Effectively reduces the water content of red mud, reducing the difficulty of subsequent stacking or recycling.
  • Closed filtration, environmentally friendly: Reduces the leakage of alkaline liquid in red mud and reduces the risk of environmental pollution.
  • Strong adaptability: Pressure, filter cloth type, and feeding method can be adjusted according to different process requirements.

3. The Key Role of Industrial Filter Cloth in Red Mud Treatment of Chamber Filter Press

The filter cloth is the core component of whether the chamber filter press can achieve efficient solid-liquid separation. For red mud treatment, suitable industrial filter cloth needs to have the following characteristics:

  • Alkali corrosion resistance: Red mud contains strongly alkaline solutions, and the filter cloth must have good alkali resistance to extend its service life.
  • High strength and wear resistance: During the operation of the chamber filter press, the filter cloth needs to withstand high-pressure pressing, so it must have excellent tensile strength and wear resistance.
  • Excellent water permeability and solid retention rate: Ensure that the liquid in the slurry can quickly pass through the filter cloth, while efficiently retaining fine particles, improving the dryness of the filter cake.
  • Good filter cake stripping property: Reduce filter cake adhesion, improve filter cloth regeneration ability, and reduce cleaning and maintenance frequency.
