 What is Coconut Shell Activated Carbon?

Coconut shell activated carbon (CSAC) is a highly porous filtration media produced by carbonizing and activating coconut shells. The activation process creates millions of micro and nano-sized pores, resulting in a very high surface area (typically 1000–1500 m²/g).

This porous structure enables it to trap contaminants efficiently, making it one of the most widely used materials in water purification.

How It Works (Adsorption Mechanism)

Coconut shell activated carbon works through adsorption, not absorption.

  • Contaminants adhere to the carbon surface

  • Micropores capture and retain pollutants

  • Clean water flows through

The extremely large internal surface area allows effective removal of even trace contaminants.

Role in Water Treatment

1. Removal of Chemical Contaminants

  • Chlorine and chloramines

  • Volatile Organic Compounds (VOCs)

  • Pesticides and industrial chemicals

High microporosity makes it especially effective for small molecular impurities.

2. Heavy Metal Removal

  • Lead

  • Mercury

  • Cadmium

Helps reduce toxic metal concentration in water when used in proper systems.

3. Taste & Odor Improvement

  • Eliminates chlorine smell

  • Removes unpleasant taste

  • Improves overall water quality

Widely used in drinking water filters and RO systems.

4. Reduction of Organic Load

  • Reduces COD (Chemical Oxygen Demand)

  • Reduces BOD (Biological Oxygen Demand)

  • Removes color and turbidity

5. Micro-Pollutant Removal

  • Pharmaceutical residues

  • Disinfection by-products (THMs)

  • Trace organic impurities
