When industrial filter cloth is used with filter press equipment for solid-liquid separation, careful consideration of multiple factors is essential to achieve optimal filtration results. Bolian, a manufacturer specializing in custom filter cloth solutions for years, outlines key points to observe during industrial filtration:
Solid Particle Load on Yarns
If the size of solid particles is comparable to the pore size of the industrial filter cloth, the particles may penetrate the gaps between yarns in multifilament fabrics and become trapped. Such particles are difficult to remove via backflushing.
Precipitation from the Solution
This type of precipitation behaves similarly to organic buildup on the filtration media, causing blockage of the media's pores.
Critical Pressure
Every filtration system has a critical pressure threshold. Exceeding this value causes the particle bridge on the media to collapse, resulting in direct particle penetration into the filter cloth. In laboratory settings, critical pressure can be identified by gradually increasing the filtration pressure during the process.
Impact of Filter Cloth Structure
As fluid passes through a multifilament fabric, the flow rate through and around the yarn depends on the yarn twist and the size of the micropores between the yarns. These pore sizes are determined by the weaving method, such as plain weave, twill weave, etc.
