Rough Filtration (Depth Filters / Filter Paper)

Coarse filtration (depth filter, filter paper) is a unified name for the pretreatment method installed to prevent the intrusion of dust and foreign matter that flows into water treatment facilities. It is used in a variety of environments, including general qualitative analysis, water and air pollution analysis, soil testing, radioactive dust concentration measurement, and dust concentration measurement in metal mines, factories, and refineries. Not only is the filtration speed relatively fast, but the sediment retention is high, so filtration can be done efficiently in a short time. Materials include general α-cellulose, borosilicate glass fiber, and tetrafluoroethylene resin (PTFE).
