Filtration is an important process applied to solids, liquids and gases. By products and waste are now included in materials requiring filtration due to environmental protection compliances. As the field of filtration becomes broader and more sophisticated, so does the equipment and the filter media required to meet the demands. Greater technical expertise and experience are needed to accurately advise and select the correct filtration media for a specific process.
White filter papers are produced from bleached fibers of hardwood, soft wood, cotton or combinations, while tan or brown filter papers are manufactured from unbleached fibers. Both white and brown filter papers are available in smooth or crepe surfaces. These grades vary in basis weight, thickness and micron retention making them suitable for many different filtration processes. In producing die cut sheets of filter paper, a drawing showing specific detailed dimensions is used to assure high quality controls. |
