The belt filter press is an efficient dewatering equipment that processes concentrated sludge after the concentration tank, forming it into a sludge cake. Key features include automatic control operation, continuous production, stepless speed regulation, and applicability to various sludge types.

After thorough mixing with flocculant, the sludge enters the gravity dewatering zone where it relies on its own weight to remove significant amounts of water. The process continues through multiple stages:

• Sludge distribution via specialized equipment for even filter belt coverage
• Pre-compression dewatering in the wedge-shaped pressing section
• Final pressing zone where the sludge cake is formed

This equipment is suitable for dewatering various sludge types including:

• Mixed sludge, nitrifying sludge, and residual activated sludge from urban sewage treatment
• Industrial sludge from metallurgy, mining, chemical, papermaking, printing and dyeing, leather, electroplating, brewing, coal, and sugar industries

Optimal Performance: Particularly effective for activated sludge, metallurgical sludge, flotation concentrate, and tailings (coal).
