OptiFiber® Pile Cloth Media

OptiFiber® pile cloth media have been specially developed for water and wastewater filtration. The pile cloth media combines high removal efficiency, efficient backwash capability and long-term stability. OptiFiber® are cloths with a multi-dimensional structure, consisting of a filter-active pile layer and a non-filter-active backing. The backing, made of continuous filaments with large flow-relevant pores, serves as a carrier for the pile layer. The pile layer is woven into the backing and consists of multiple filaments or fibers.

Pile cloth media can be defined by the height of the straightened pile fibers [mm], the diameter of the individual filaments/fibers [µm], the specific surface area of the pile fibers [m²/m²], the weight per unit area of the pile fabric [g/m²], the size of the flow-relevant pores [μm] and the open area [%] of the backing fabric. A statement about the filter performance and long-term stability can only be made through many years of experience in using pile fabrics for various applications. The interaction of the individual parameters abstracts the pore structure of the pile layer. A defined pore size for pile fabrics or the pile layer does not exist by definition.
