Activated Carbon
Formula: C (carbon) | Appearance: Black granular/powder | Solubility: Insoluble in water
What is Activated Carbon?
Activated Carbon (C (carbon)) is a key water treatment chemical. Appearance: Black granular/powder. Solubility: Insoluble in water. It is widely used in drinking water purification, industrial wastewater treatment, and process water conditioning.

How to Select the Right Grade
- Water quality analysis: pH, turbidity, COD, TSS, heavy metals
- Treatment stage: Primary coagulation vs polishing
- Industry: Different wastewater characteristics require different grades
- Jar testing: Always confirm dosage via laboratory jar test

Dosage Guide
| Application | Dosage Range | Notes |
|---|---|---|
| Water treatment | 5-50 mg/L (PAC) | Batch or continuous |
| Filtration | GAC bed | EBCT 5-15 min |
| COD removal | 50-500 mg/L | Depends on COD |
| Gold recovery | 10-50 g/L CIP | Concentration |

FAQ
GAC vs PAC?
GAC (granular) for filtration columns, PAC (powder) for direct dosing. GAC for continuous, PAC for batch treatment.
Coconut vs Coal-based?
Coconut shell: harder, lower ash, better for water. Coal-based: higher density, more economical, better for gas.
When to replace?
Monitor effluent quality. Replace when iodine number drops below 600 or breakthrough occurs.
Can it be regenerated?
Yes, GAC can be thermally regenerated 5-10 times. PAC is typically single-use.
Iodine number meaning?
Higher iodine number = more micropores = better adsorption for small molecules. 900+ is good for water treatment.
