Plate filters, also known as filter presses, are widely used in various industries for solid-liquid separation. These filters utilize a series of vertical plates with filter media to efficiently separate suspended solids from liquids. Plate filters are versatile and offer excellent filtration capabilities, making them ideal for numerous applications across different sectors. In this article, we will explore the different types of plate filters and their respective applications.
Recessed Chamber Filter Press:The recessed chamber filter press is the most common type of plate filter. It consists of a series of filter plates with recessed cavities, separated by filter cloths. The plates are clamped together to form a chamber, and the slurry is pumped into these chambers. The solids are retained within the chambers while the filtrate passes through the filter media, resulting in drier filter cakes. Recessed chamber filter presses are widely used in wastewater treatment, mining, chemical, and pharmaceutical industries.
Membrane Filter Press:Membrane filter presses are an advanced version of the recessed chamber filter press. These filters have an additional elastic membrane attached to each plate. The application of high-pressure air or water to these membranes compresses the filter cake further, reducing the residual moisture content. Membrane filter presses are particularly effective in processes where low moisture content is desired, such as in the production of che
