Technical data sheet & illustrative COA reference · Powdered activated carbon
Wood Based Powdered Activated Carbon
Wood based PAC with configurable fineness, methylene blue, pH, ash and filtration properties for liquid-phase dosing and decolorization.
- Fine wood-based powdered activated carbon (200 mesh / 75 µm and 325 mesh / 45 µm) engineered for rapid liquid-phase adsorption kinetics in batch dosing and municipal water systems.
- Configurable via steam activation (neutral/alkaline pH) or phosphoric-acid activation (acidic/washed pH 3–7) with 120–200 mg/g methylene blue and controlled filter cake permeability.
- Tested to ASTM D5158 for wet screen fineness and ASTM D4607 for iodine number, with free lab samples provided to verify settling rate and press filterability prior to bulk shipment.
1Technical specifications
| Raw material | Wood chips, sawdust or wood charcoal; phosphoric-acid or steam activation by grade |
|---|---|
| Physical form | Powdered activated carbon |
| Standard sizing | Common 200 or 325 mesh grades; target screen passing rate is specified by order |
| Iodine value | Typical configurable range: 800-1,050 mg/g |
| Methylene blue | Typical configurable range: 100-200 mg/g |
| Ash | Typical range: 5-18%; higher-quality decolorization grades can target <=10% |
| Moisture | Typically <=5% |
| pH | Typical phosphoric-acid grades: approximately 3-7, depending on washing |
| Bulk or tapped density | Typical reference range: 250-450 g/L; measurement method must be stated |
| Custom manufacturing | 200/325 mesh, iodine value, methylene blue, pH, caramel decolorization, iron, lower phosphorus or ash and filtration behavior. |
PAC particle size can be evaluated by ASTM D5158. Iodine value does not replace application-specific decolorization, filtration-time or methylene-blue testing. Final guaranteed values and test methods must be agreed in the order specification.
