Recessed vs Membrane Filter Plates: A Guide for Efficient Industrial Filtration

A filter press relies on high-quality filter plates to efficiently separate solids from liquids. These plates form chambers where slurry is captured, producing clarified filtrate and a manageable filter cake. Selecting the right filter plate is crucial for optimal performance, cake dryness, and overall process efficiency. At Kerte, we provide reliable filter plates designed for diverse industrial applications.

Two common types of filter plates are recessed filter plates and membrane filter plates. While both serve the primary purpose of solid-liquid separation, their design and performance characteristics differ, influencing efficiency and output.

Recessed filter plates have a rigid, recessed surface that holds the filter cloth in place. Slurry enters the chamber created by the filter plate, and solids form a cake. Recessed plates are known for their durability and simplicity. They are ideal for processes where moderate cake dryness is sufficient and mechanical compression is not needed. Industries such as chemical manufacturing, mining, and wastewater treatment frequently use recessed filter plates in filter press systems for reliable operation and minimal maintenance.

Membrane filter plates, on the other hand, include a flexible membrane over the filter plate surface. After initial filtration in the filter press, the membrane inflates using air or water to compress the filter cake, significantly reducing moisture content. Membrane plates provide superior dewatering, faster cycle times, and higher cake dryness, which is essential in food processing, pharmaceuticals, and chemical industries. Proper handling and periodic inspection ensure membrane filter plates maintain peak performance.

Choosing the right filter plate for your filter press depends on your process needs. Recessed filter plates offer durability and simplicity, while membrane filter plates deliver advanced dewatering and efficiency for demanding applications. At Kerte, we provide both options, helping industrial operators optimize filtration, improve productivity, and achieve consistent results.
