What are filter leaves and how do they work?
Filter leaves are large metal screens, often multi-layered with very fine wire mesh, that are placed along the length of a filter vessel. These are used in both horizontal and vertical pressure leaf filter configurations. The center layer is a coarser, thicker mesh which provides support to the finer, more flexible outer layers. The fine mesh outer layers are more tightly woven and use smaller wires which decreases their pore size, or the openings through which the solution can pass through. Depending on the weave of the wire mesh used, our filters can separate out incredibly fine particles, especially when used in conjunction with a cloth filter bag or, in some cases, a filtration aid or precoat treatment such as diatomaceous earth.
How are filter leaves used in an IFP filter vessel?
A set of leaves are connected to a central discharge manifold which runs down the length of the pressure leaf filter vessel. The number of leaves and the spacing between them depends on several factors, such as the size of the vessel, the solution being filtered, whether or not precoat has been applied, and the flow rate of the system. Our team here at Industrial Filter & Pump is happy to work with you to design and build a custom filter vessel to fit your facilities unique needs. We also supply replacement parts for the filter leaves, including o-rings, lip seals, and leaf inserts. Get in touch with us today to learn more!
