WHAT IS ADSORPTION?
Adsorption is a mass-transfer phenomenon that occurs when the pollutant is bound to an adsorbent particle surface through either physical or chemical interaction.
WHY ADSORPTION BY ACTIVATED CARBON IS PREFERRED?
- Easy accessible. Almost any carbon-containing feedstock, such as coconut shells and coal family members, may be used as the raw material for producing activated carbon.
- Affordable
- Providing a significant amount of surface area to remove pollutants. An activated carbon teaspoon has a surface area greater than a football field.
WHICH CONTAMINANT WILL BE REMOVED?
- Organic contaminants
- Micropollutants
- Odour-causing substances
WHICH CONTAMINANT CANNOT BE REMOVED?
- Microbial pollutants
- Metals
- Nitrates, and other inorganic contaminants
NOTE: The activated carbon also needs to be replaced regularly (every time after use) to maintain its effectiveness and efficiency in treating water.
