Product Overview

GAC-P is a high-activity coal-based granular activated carbon engineered for enhanced drinking water and ultra-pure water treatment. Manufactured from premium bituminous coal through optimized carbonization and steam activation, it delivers an iodine adsorption value exceeding 1000 mg/g and a specific surface area above 1000 m²/g.

With controlled ash content, low floating rate, and high mechanical strength, GAC-P offers elevated adsorption capacity compared to standard coal-based GAC. It is designed for high-duty municipal, industrial, and food-grade water systems where maximum organic removal per unit volume is required.

Key Application Areas

  • Ultra-Pure Water Systems — Provides enhanced TOC and trace organic removal in semiconductor, pharmaceutical, and power generation deionized water loops.
  • Beverage & Food Processing — Purifies high-throughput ingredient water for breweries, soft drink bottling, and food manufacturing where rapid dechlorination and consistent quality are critical.
  • Point-of-Entry (POE) Water Treatment — Handles higher organic loading and extended service intervals in whole-house and commercial building water treatment systems.

Key Advantages

  • Enhanced Adsorption Capacity: Iodine >1000 mg/g delivers 10–15% higher organic removal capacity than standard 900 mg/g grades, extending time-to-breakthrough and reducing changeout frequency.
  • High-Strength Granular Form: >90% crush strength and low floating rate ensure stable bed performance through repeated backwashing and hydraulic stress.
  • Cost-Effective High Performance: Bituminous coal base provides premium adsorption capacity at a lower cost than equivalent coconut shell grades for large-volume installations.
  • Compatible with Existing Systems: Same granular geometry and density as standard GAC allows direct upgrade in existing vessels without system modification.

  • Q
    What is the difference between GAC-P and GAC-P S?
    A

    GAC-P delivers >1000 mg/g iodine with standard pH for high-capacity water treatment. GAC-P S is the acid-washed variant with pH 5–8 and methylene blue >160 mg/g for pH-sensitive applications.

  • Q
    Is GAC-P suitable for groundwater remediation?
    A

    While capable of organic adsorption, GAC-P is optimized for drinking water and ultra-pure water. For groundwater pump-and-treat with variable contaminants, consult our technical team for media selection.

  • Q
    Can GAC-P remove chloramine as well as chlorine?
    A

    GAC-P adsorbs free chlorine effectively. For dedicated chloramine decomposition, PSD-MAC catalytic carbon is recommended.

  • Q
    What is the typical service life in municipal POE systems?
    A

    Under standard municipal water conditions with moderate organic loading, expect 18–24 months before breakthrough. Higher organic loads may shorten this interval.
