Filter media are materials used in water filtration systems to remove dirt, contaminants, or unwanted chemicals in water, resulting in cleaner water suitable for industrial use or consumption.
Principles of Filter Media OperationFilter media operate based on the following principles:
- Physical Filtration Relies on the pore size of the filter media to trap sediments, dust, and suspended particles, such as sand filters or anthracite.
- Ion Exchange Utilizes filter media capable of exchanging ions in water, such as ion exchange resin, which helps reduce water hardness.
- Adsorption Uses filter media with a high surface area to absorb contaminants, such as activated carbon, which removes chlorine, odors, and organic substances.
- Oxidation Involves filter media that accelerate chemical reactions, such as manganese greensand, which removes iron and manganese from water.
