Filter papers are semi-permeable papers used for separating solid phases from liquid and filtration. Sometimes they even use filter paper to separate the solid phase from the gas phase.
Types of filter paper in terms of texture size:
Fine texture: filter papers are used to filter very fine sediments, these filters have a fine texture with a porosity of 2 to 3 microns and relatively fast It is low.
Whatman 42 and 44 and blue band S&S 5893 (Schliecher & Schuell 5893) is an example of this type of filter paper.
Medium texture: used for smoothing sediments containing medium grains. These filters have a relatively coarse texture with a porosity of 8 to 10 microns and a relatively high speed. Whatman 40 and white band S&S 5892 are examples of this type of filter paper. Coarse texture: It is used for smoothing coarse sediments and gelatinous sediments. These filters have a coarse texture with a porosity of 20 to 25 microns and high speed. Whatman 41 and black band (S&S 5891) are examples of this filter paper. be
