Automatic backwash filter

摘要

Lenzing Optifil is a fully automatic, continuous system that works according to the principle of depth, surface or cake filtration. A metal fiber fabric or fleece is used as filter material, which retains particles of different sizes either inside or on its surface. After the pre-determined degree of contamination has been reached, the filter material is cleaned by backwashing a small quantity of filtered medium, while filtration continues during the backwash.
