Carbon, Resin, and Manganese in Water Filters
Activated Carbon
Activated carbon is a granular or powdered material made from organic materials such as coconut shells, wood, or coal. Activated carbon has numerous micropores to absorb contaminants in water.
Main functions:
- Eliminates chlorine, odor, and bad taste
- Filtering organic compounds and heavy metals
- Purifying drinking water
Types of activated carbon: GAC (granular), PAC (powdered), dan block carbon.
Resin (Ion Exchange Resin)
Resin is a synthetic polymer-based granule that works on the principle of ion exchange. It consists of cation resin (exchanges positive ions) and anion resin (exchanges negative ions).
Main functions:
- Soften water (remove Ca and Mg)
- Removes iron, manganese, nitrates and sulfates
- Used in RO systems, food and pharmaceuticals
The resin needs to be regenerated periodically with a salt or acid solution.
Manganese (Media Manganese Greensand)
Manganese is a manganese oxide-based filter media such as greensand or activated zeolite, which functions to oxidize and filter heavy metals.
Main functions:
- Eliminates iron (Fe) and manganese (Mn)
- Eliminates sulfur (H₂S) odor
- Reduces color and turbidity in groundwater
Brief Comparison
Media Filter | Main Functions | Target Contaminants | General Applications |
Activated Carbon | Adsorption of odors, chlorine, organics | Odor, taste, chlorine, pesticides | Home, drinking, industrial filters |
Resin | Ion exchange | Ca, Mg, NO₃⁻, Fe | Water softener, RO, pharmaceutical |
Manganese | Oxidation and filtration | Iron, manganese, H₂S | Ground water, industry, household |
To choose the right water filter media according to your needs (household, industrial, groundwater, or PDAM water), consult a trusted technician or supplier.
