Filter disc

Function • Multiple ceramic filter discs are stacked in a module. • During operation, these stacks rotate to control the cake layer formed during filtration. • The feed through the membrane is divided into two streams: the permeate/filtrate and the concentrate. • Particles larger than the membrane pores are retained and concentrated in the concentrate. • Particles smaller than the membrane pores flow through the porous structure (support) and are collected and discharged in a hollow shaft. Ceramic Filter Discs • Rotating filtration discs, or dynamic cross-flow filters, are disc-shaped elements with an externally coated ceramic membrane. • Available in various sizes and variations (geometries) • The functional layer (membrane) is attached to the outside, allowing the filtration direction to proceed from the outside to the inside, known as 'outside-in'.
