Key Features

  1. Superior Adsorption Capacity:
    With an iodine sorption value of over 900 mg/g, GAC type activated carbon provides excellent contaminant removal, making it ideal for drinking water treatment and ensuring cleaner, purer water.

  2. Purity and Low Contaminants:
    This activated carbon has a low moisture content (≤ 5%) and low ash content (≤ 15%), ensuring minimal impurities and high efficiency in the filtration process.

  3. High Mechanical Strength:
    GAC type activated carbon maintains its structural integrity with high hardness (≥ 90%), making it suitable for long-term use in high-flow water systems without losing its effectiveness.

  4. Customizable Particle Sizes:
    Available in various particle sizes, such as 8×30 mesh (0.6–2.36 mm) and 12×40 mesh (0.43–1.7 mm), it can be customized to meet specific filtration requirements for different water treatment applications.


Applications

  • Drinking Water Treatment:
    Ideal for the purification of drinking water, ensuring that it meets the highest health and safety standards for consumption.

  • Ultra-Pure Water Treatment:
    GAC activated carbon is highly effective in the production of ultra-pure water, often used in industries like pharmaceuticals and electronics where water purity is critical.

  • Food and Beverage Water Treatment:
    Widely used in thefood and beverage industry, GAC type activated carbon helps in decolorization and purification of water used in beer, beverages, and other food processing.

  • Post-Treatment of POU Water:
    It is also used for point-of-use (POU) water treatment, providing effective filtration in residential and commercial water purification systems.


Explain

  1. Testing Standards:
    GAC type activated carbon is tested in compliance with the national standard GB/T 7702-2008 for granular activated carbon derived from coal.

  2. Surface Area Measurement:
    The specific surface area is measured using the BET method, ensuring high-quality performance and adsorption efficiency.

  3. Product Test Results:
    All test results are based on average measurements, guaranteeing consistent quality in every batch of activated carbon.
