The cardboard filter press represents a specialized filtration system designed for efficient solid-liquid separation across various industries. This equipment utilizes disposable cardboard filter plates as the primary filtration medium. Unlike conventional filter presses that use reusable cloth media, the cardboard plate press-filter system offers superior filtration precision with minimal particle release, making it particularly valuable for applications requiring high-purity standards.

A standard cardboard filter press consists of a robust frame structure supporting a series of filter plates and frames arranged in parallel configuration. The system includes a hydraulic or mechanical closing device that applies substantial pressure to create sealed chambers between adjacent plates. Each chamber contains a cardboard filter sheet precisely cut to match the plate dimensions, forming individual filtration units when the press is closed and pressurized.
The pharmaceutical industry extensively utilizes cardboard filter press for fine filtration applications where product purity is paramount. These systems effectively separate active pharmaceutical ingredients (APIs) from reaction solvents, remove catalyst residues from process streams, and clarify sensitive biological solutions. In fine chemical production, the cardboard filter press for liquid filtration achieves exceptional clarity while handling challenging materials such as viscous polymers, aggressive solvents, and temperature-sensitive compounds.
The cardboard elements effectively remove fine precipitates, haze-forming proteins, and processing aids while preserving the organoleptic properties of the final product. Applications include edible oil clarification, beverage stabilization, sugar syrup purification, and starch processing.
Environmental applications leverage the cardboard filter press for liquid filtration in treating industrial effluents containing fine suspended solids, heavy metal hydroxides, and organic sludges. The system produces exceptionally clear effluent suitable for direct discharge or further polishing, while generating dense, low-moisture cakes that reduce disposal volumes and costs.
The evolution of filtration technology has ushered in significant improvements in cardboard filter press design and functionality. Modern systems combine engineering innovation with practical operational enhancements to deliver superior performance across industrial applications.
