Our advanced chemical filter, designed specifically for pretreatment applications across various industries. Chemical filters remove contaminants in fluids through adsorption, chemical reaction, or catalysis.
Adsorption: Adsorbents (such as activated carbon) have a large number of micropores and a high specific surface area, and can adsorb harmful substances in fluids. The adsorption process is achieved through intermolecular van der Waals forces, chemical bonds, and other actions. For example, activated carbon can adsorb harmful gases in the air, such as formaldehyde and benzene.
Chemical reaction: Chemical reactants in the filtration medium can react chemically with specific contaminants in the fluid and convert them into harmless substances. For example, in some water treatment filters, ion exchange resins are contained, which can undergo exchange reactions with calcium and magnesium ions in water to reduce the hardness of water.
Catalysis: Catalysts can accelerate the chemical reaction rate of contaminants in fluids and make them convert into harmless substances more quickly. For example, in automobile exhaust treatment, catalysts can convert harmful carbon monoxide, nitrogen oxides, etc. into harmless substances such as carbon dioxide and nitrogen.
