Description
Belt filter press Information
The Belt Filter Press stands as an industry benchmark for efficient solid-liquid separation. Through a continuous, multi-stage dewatering process, it economically and rapidly separates various slurries into dry solids and clear filtrate. Whether handling municipal sludge or complex industrial waste, this equipment is the ideal solution for enhancing processing efficiency, reducing disposal costs, and achieving environmental compliance.
How belt filter presses work
-
Chemical Conditioning: The slurry is precisely mixed with flocculants to form firm flocs ideal for dewatering.
-
Gravity Drainage: The flocculated slurry is spread on a coarse mesh belt, allowing a significant amount of free water to rapidly separate by gravity.
-
Wedge Pre-Pressing: The slurry enters the wedge zone, where gentle linear pressure is applied to release more water and form a stable sludge mat.
-
High-Pressure Shear Dewatering: The sludge mat is subjected to progressively increasing shear and compression forces between "S"-shaped press rollers, removing capillary water to form a firm filter cake.
