Wood Based PAC at a glance
What sets it apart, and where it is used.
-
Material & pore structure
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.
-
Washing & grade options
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.
-
Direct Shizuishan plant supply
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.

Where Wood Based PAC is used
Typical applications and process selection checks.
-
Define the target liquid, contaminant or color body, dosage point, contact time and downstream filtration method.
-
State a minimum passing rate for 200 or 325 mesh instead of using a nominal mesh description alone.
-
Use methylene blue, caramel or actual-liquid testing when larger molecules or color removal control the result.
-
Review pH, ash, iron, phosphorus and filtration time where product purity or filterability matters.

Wood Based PAC sourcing questions
Answers use the same values as the tables on this page.
Should PAC hardness be specified?
No. Particle hardness is not a meaningful acceptance field for powdered carbon. Use particle-size distribution, methylene blue, decolorization, filtration time, density and dispersibility instead.
Are 200 and 325 mesh grades available?
Both are common sourcing directions. The contract should state the target mesh and minimum passing rate rather than only a nominal mesh name.
How is a sample selected?
The target liquid, dosage and filtration method should be shared first so the sample grade and quantity match the intended bench test.
