Filtration Definition :-The separation of solids from a suspension in a liquid with the help of a porous medium or screen which retains the solids and allows the liquid to pass is termed as filtration.; The operation of separating a solid from a liquid by means of a porous medium (usually a wire or fabric filter cloth) is called as filtration.
Screening – ForestBioFacts
Screening The purpose of screening is to remove debris and solid contaminants from the recycled fibre pulp. This uses appropriate screen configurations according to particle size, shape, and deformability of the contaminants. Separating fibres according to characteristics such as their length or flexibility is also necessary sometimes.
