WT-P
purestar
WT-P coal granular activated carbon is manufactured from selected bituminous coal through carbonization and high-temperature steam activation. The product offers high iodine adsorption value (>900 mg/g), excellent mechanical strength (>90%), and low ash content.
Its 8×30 mesh particle size provides optimal balance between pressure drop and contact efficiency. Ideal for biological activated carbon (BAC) processes, tertiary treatment after biological systems, and reclaimed water production in municipal and industrial facilities.

High Mechanical Strength & Cost-Effective Purification
Our coal-based activated carbon is manufactured from premium bituminous coal through steam activation, delivering exceptional hardness (>90%) and abrasion resistance for demanding industrial applications.
With iodine adsorption values exceeding 900-1000 mg/g and customizable particle sizes (4×6 mesh to 12×40 mesh), it ensures optimal performance in drinking water treatment, wastewater purification, and air filtration systems. The high bulk density (350-550 kg/m³) and superior CTC adsorption (50-90%) make it ideal for VOC removal, solvent recovery, and gas-phase applications.
Available in granular (GAC), powdered (PAC), and columnar forms for maximum operational flexibility.

Q1: What is the service life of WT-P in water treatment?
A: Service life depends on influent quality and target effluent standards. Typical replacement intervals range from 1-3 years for municipal applications. Carbon activity monitoring is recommended.
Q2: Can WT-P be thermally regenerated?
A: Yes, WT-P is suitable for thermal reactivation, making it economical for large-scale continuous operations.
Q3: Is WT-P effective for emerging contaminants like pharmaceuticals?
A: WT-P provides good adsorption for many trace organic contaminants. For specific PPCP removal, contact our technical team for optimization recommendations.
Q4: What backwash rates are recommended?
A: Typical backwash rates are 25-35 m/h for 10-15 minutes to maintain bed fluidization and remove suspended solids.
Q5: Does WT-P require acid washing?
A: Standard WT-P is suitable for most applications. For ultra-pure water or pH-sensitive processes, our acid-washed variants are available.
