Chemical & Fine Chemical
Filter presses are widely used in the chemical and fine chemical industries for solid–liquid separation. In the production of dyes, pigments, catalysts, resins, salts, and intermediates, these presses improve production efficiency, product purity, and material recovery rates.
Due to the corrosive nature of many raw materials and reactants, chemical filter presses are designed with corrosion-resistant materials. We also offer high-temperature-resistant filter plates and customized solutions for a wide range of materials and processes.
For pigment and dye industries, automatic chamber filter presses are ideal for dewatering slurry and removing water and impurities after synthesis.
Catalyst and intermediate recovery often requires stainless steel filter presses—for example, for filtering palladium-carbon, platinum catalysts, molecular sieves, and fine organic intermediates after chemical reactions.
Crystallized inorganic salts such as sodium chloride, sodium sulfate, potassium nitrate, or oxalates can be processed with chamber filter presses featuring backwash systems for efficient filtration and mother liquor recovery.
High-viscosity materials like resins, colloids, polymer emulsions, PVDF, polyacrylamide, polyvinyl alcohol, and latex require filter presses with anti-stick filter cloths to prevent clogging.
For pesticides and fine agrochemicals that contain volatile organic solvents or emit pungent odors, explosion-proof enclosed filter presses ensure safe and automated operation.
