Selection overview
Water Treatment selection starts with operating data
Activated carbon selection for water treatment starts with the water chemistry and treatment objective. GAC is normally reviewed for fixed beds and polishing, while PAC suits batch dosing or temporary treatment. Mesh, contact time, backwash conditions, leachables and required documents must be confirmed together.
Recommended sourcing direction
Coal based or coconut shell GAC for fixed beds; PAC for dosing and emergency treatment
The figures below are common sourcing references, not an application-performance guarantee. Final grade, test methods and batch limits are confirmed after the operating conditions are reviewed.
| Common GAC mesh | 8x30, 12x40 or 20x40 mesh are common directions; vessel design controls the final range |
|---|---|
| Iodine value | Coconut shell GAC: typically 950-1,100 mg/g; coal based GAC: typically 800-1,050 mg/g |
| Hardness | Typically >=90%; higher-hardness directions can be reviewed for backwash and repeated handling |
| Moisture | Typically <=5% |
| pH | Typically 8-11; washed or acid-washed grades are specified separately |
| Application-specific checks | Target-contaminant testing, dechlorination, acid-soluble matter, iron and leachables as required |
Application data needed for grade matching
Water source and analysis, target contaminant, flow rate, vessel size, empty-bed contact time, backwash condition, target mesh, replacement cycle, quantity and destination.
Qualification boundary
Confirm suitability with the actual system and agreed test method
Drinking-water suitability and compliance documents are grade- and destination-specific. They must be confirmed for the actual product rather than inferred from a general water-treatment label.
System qualification
Move from operating data to a defensible grade specification
The selection process separates system conditions from product properties so the quotation can state relevant tests and acceptance values.
Process factors to send
- Water analysis and target contaminant or treatment objective
- Flow, vessel dimensions and empty-bed contact time
- Retaining screens, backwash rate and acceptable pressure drop
- Required replacement cycle, discharge limits and destination-specific documents
Recommended validation path
- Screen grades against the water analysis
- Confirm mesh and hydraulic fit
- Test target-contaminant removal or dechlorination
- Agree specification, methods and batch COA fields
Performance boundary: Operating results depend on the actual system. A sample or pilot result should use an agreed method and representative conditions.

Timing starts after the product specification, packing, order documents and agreed payment conditions are confirmed.
Export terms by route
Qingdao or Tianjin are commonly used; the final loading port is confirmed with the route and trade term.
FAQ
Water Treatment sourcing questions
Coal based GAC offers a broad pore structure for many industrial water applications. Coconut shell GAC is often selected when hardness, micropore adsorption and clean handling are priorities. Water analysis and system design should decide the grade.
No. Mesh, hardness, ash, pH, contact time, target contaminant, dechlorination behavior and application testing can be equally important.
Yes. Standard samples are normally free, with international courier paid by the buyer. Share the intended test method and required quantity first.
