Key Features

Ultra-High Adsorption Performance
Iodine value exceeding 1000 mg/g and highly developed pore structure deliver exceptional organic contaminant removal, effectively reducing TOC and residual chlorine in drinking water, ultrapure water, and food process streams while extending filter bed service intervals.
Low Floating Rate & Fast Settling
Controlled floating rate below 6% ensures rapid particle settling during initial filling and backwashing cycles, minimizing carbon loss to overflow and maintaining stable bed height in continuous-flow filtration vessels.
Superior Mechanical Durability
Exceptional hardness above 90% resists attrition under continuous hydraulic loading and repeated backwashing, preserving particle integrity and preventing fine carbon migration that could foul downstream membranes or piping.
Low Ash & Moisture Stability
Controlled ash content below 15% and moisture below 5% ensure consistent adsorption kinetics and prevent inorganic leaching, making it suitable for food-grade water treatment and sensitive ultrapure water systems.

Applications

Drinking Water Deep Treatment: Municipal water plants and centralized supply systems must remove trace organic pollutants, residual chlorine and disinfection byproducts. GAC-P's ultra-high iodine value and surface area deliver extended service life and higher pollutant loading capacity than standard coal grades.
Ultrapure Water Production: Industrial UPW systems require core adsorption media to reduce organic load and protect downstream membrane and resin equipment. GAC-P's enhanced capacity lowers TOC more effectively, supporting ppb-level water purity targets.
Food & Beverage Process Water: Conventional food and beverage production needs reliable water quality improvement without premium pricing. GAC-P provides adsorption performance approaching coconut shell carbon at a coal-based cost point.
High-Load Industrial Pretreatment: Manufacturing process water with elevated organic content demands higher capacity media. GAC-P's 1000 mg/g iodine value handles heavier loads with longer intervals between replacement.
