Product parameters
Activated carbon selection table.
Recommended starting ranges for technical discussion. Final values depend on the stream, test method and buyer specification.
| Carbon option | Iodine value | Typical size | Suitable conditions | Selection effect |
|---|---|---|---|---|
| Acid-washed coconut GAC | 1000–1200 mg/g | 12×40 mesh | Pretreatment organics / chlorine | Low ash and high hardness |
| High-purity GAC | 900–1100 mg/g | 12×40 mesh | RO protection and polishing | Controlled leachables |
| Fine granular carbon | 1000–1200 mg/g | 20×40 mesh | Compact polishing beds | Faster kinetics; higher pressure-drop review |
| Custom washed grade | Project-specific | Buyer-selected mesh | Critical high-purity duty | Rinse and extractables data by agreement |

Frequently asked questions
Technical answers for buyers.
Need a faster review? Send the available process data with your inquiry.
Yes. Share your process data and target limits so we can prepare a relevant evaluation sample. Freight is normally paid by the buyer.
Iodine value, particle size, strength, moisture and packing can be discussed against the equipment and required outlet quality.
Please provide the stream composition, target contaminants, inlet and outlet limits, flow, temperature, humidity or pH, contact time and current equipment.
Service life depends on actual contaminant loading, competing compounds and operating conditions. Pilot testing and breakthrough monitoring provide the most reliable estimate.
