Product: Vacuum Drum Filter

Country: United States

Application: Calcium Phosphate Aqueous Solution

Solid-liquid separation is a crucial step in starch processing, directly impacting starch purity, whiteness, and production efficiency, Vacuum Drum Filter is ideal for the recovery of inorganic salts (calcium phosphate, calcium carbonate, gypsum, aluminum hydroxide, various metal hydroxide precipitates, catalysts) in the chemical and pharmaceutical industries. The following uses calcium phosphate aqueous solution as an example:

Why is a vacuum drum filter suitable for processing calcium phosphate aqueous solutions?

Excellent solid recovery rate: The vacuum drum forms a stable filter cake through the filter cloth, followed by washing and drying, achieving an extremely high solid recovery rate (typically >99.5%). This is crucial for achieving the goal of "focusing on solid recovery," minimizing the loss of valuable solids.
Gentle and continuous separation process: The entire process is carried out under relatively gentle vacuum suction. For solids like calcium phosphate, which may have specific crystal structures, this effectively avoids crystal breakage, facilitating the recovery of high-quality solid products.
Excellent washing effect: If your calcium phosphate solid contains mother liquor or soluble impurities, the countercurrent or cocurrent washing function of the drum can wash them very efficiently, improving the purity of the solid phase.
Adaptable to low-to-medium concentration feeds: Solid content below 10% falls within the ideal processing range of the vacuum drum filter (typically handling slurries with solid content of 1%-30%). Even with fluctuations in feed concentration, the equipment operates stably.
Automation and Continuity: Fully automatic continuous operation, suitable for large-scale industrial production, with low labor intensity and stable operation.

Processes where vacuum drum filters excel:

Applications requiring efficient countercurrent or cocurrent washing: This is one of its greatest advantages. After the filter cake forms on the drum, multiple washing zones can be set up to replace the mother liquor with clean solvent, greatly improving product purity.
Processes requiring continuous and automated production: As a continuous operating device, it is easy to integrate with upstream and downstream processes to achieve full-process automation, suitable for modern large-scale production.
Processing materials with a certain degree of filter cake permeability: Vacuum suction can effectively penetrate the filter cake layer, achieving good descaling.
Applications where the solid phase is the product and a high recovery rate is required: The filter cloth has good sealing properties, resulting in minimal solid loss.

Vacuum drum filters are the benchmark equipment in continuous filtration, washing, and dewatering. When processing highly filterable, high-value-added slurries requiring washing, they often outperform batch equipment (such as plate and frame filter presses) or other continuous equipment in terms of efficiency, recovery rate, and automation.
