Tangential Flow Filtration (TFF), also called Cross Flow Filtration (CFF), is a rapid and efficient method for filtration and separation of solutions containing biomolecules, or particles such as viruses, bacteria or cellular material. Reverse osmosis or RO is a filtration method that is used to remove ions and molecules from a solution by applying pressure to the solution on one side of a semipermeable or selective membrane. A particulate air filter is a device composed of fibrous, or porous materials which removes solid particulates such as dust, pollen, mold, and bacteria from the air.Filters containing an adsorbent or catalyst such as charcoal (carbon) may also remove odors and gaseous pollutants such as volatile organic compounds or ozone. Cations are positive ions missing one or more electrons, resulting in a net positive charge. By Margenett Moore-Roberts, Global Head of Inclusive Diversity .
