Membrane presses

Our range of membrane filter presses has plate pack sizes 470, 630, 800, 1000, 1200 and 1500mm square. The membrane plate is a technological development of the standard recessed plate. In our presses, every plate or every other plate has a flexible face that covers both sides of the plate.

The fundamental principle of membrane operation realises that approximately 75 - 80% of the product to be filtered passes through the filter press in the first third of the cycle time. At this point, in each chamber two "half" cakes have been built up. Press feeding is stopped, and the flexible membrane outer surfaces are inflated by applying compressed air pressure (or water) behind the membrane surfaces. The two halves of cake in each chamber are then squeezed together under pressure, forming a single cake of a very homogenous consistency.

Membrane plates

Membrane filter press plates, made from durable materials, enable effective filtration by applying pressure to the filter cake, which maximizes liquid extraction from the solids. The membrane technology facilitates additional cake squeezing, producing drier solids and improved products. These plates are available in various sizes and configurations, allowing customization to meet different operational requirements and filter types. Their versatility makes them suitable for wastewater treatment, food and beverage production, and mineral processing applications. With advancements in design, these plates also ensure quick and easy maintenance while promoting sustainable practices by reducing waste and energy consumption during solid-liquid separation. Overall, membrane filter press plates are essential for enhancing the performance of filtration processes across various sectors.
