Filter paper has various properties. The important parameters are wet strength, porosity, particle retention, volumetric flow rate, compatibility, efficiency and capacity.
There are two mechanisms of filtration with paper; volume, and surface. By volume filtration the particles are caught in the bulk of the filter paper. By surface filtration the particles are caught on the paper surface. Filter paper is mostly used because even a small piece of filter paper will absorb a significant volume of liquid.The raw materials are different paper pulps. The pulp may be from softwood, hardwood, fiber crops, mineral fibers.
