技术规格

The following table outlines the key physical and chemical properties of our standard granular activated carbon, based on rigorous laboratory testing and aligned with international benchmarks such as ASTM and AWWA standards. Values represent minimum or maximum limits unless specified as typical. Dual units (metric/imperial) are provided for global compatibility.

*Note: Specifications may vary slightly based on raw material source (coal or coconut shell). Custom formulations available for specific applications. All performance data is verifiable through independent lab results.

应用

Granular activated carbon is a versatile filtration medium with proven efficacy in diverse industries. Primary uses include:

• Potable Water Treatment: Removal of chlorine, chloramines, taste/odor compounds (e.g., MIB and geosmin), and organic contaminants like PFAS, herbicides, and hazardous algal toxins (HABs) from surface and groundwater sources.
• Wastewater and Industrial Remediation: Adsorption of VOCs, petroleum hydrocarbons (e.g., BTEX), polychlorinated biphenyls (PCBs), and heavy metals from industrial effluents, ensuring compliance with environmental regulations.
• 空气和气体净化: Elimination of odors, hazardous gases (e.g., hydrogen sulfide), and volatile organics in ventilation systems, biogas treatment, and industrial exhaust.
• Food & Beverage Processing: Decolorization, purification, and removal of impurities in bottling, brewing, and pharmaceutical water streams.
• Environmental and Groundwater Cleanup: Effective in pump-and-treat systems for site remediation, including coal combustion residuals (CCR) and solvent recovery.
• Aquarium and Pond Filtration: Maintains clear, contaminant-free water for aquatic environments.

By focusing on adsorption efficiency, GAC addresses key buyer pain points such as regulatory compliance, operational reliability, and cost savings through reduced chemical usage and extended service life.

Certifications and Standards

• Quality and Safety Compliance: NSF/ANSI 61 certified for drinking water applications; AWWA B604 for granular activated carbon; Food Chemicals Codex compliant.
• International Standards: Adheres to ASTM (e.g., D4607 for iodine, D3802 for hardness), ISO (e.g., general requirements for activated carbon), and EN 12915 for water treatment carbons.
• Environmental and Regulatory: REACH compliant for EU markets; Halal and Kosher certified options available; low extractable metals to meet global trade regulations.
• Testing and Validation: All batches undergo third-party lab verification for performance claims, with certificates of analysis provided upon request.

Packaging and Handling

• 标准包装: Available in 25 kg (55 lb) multi-layer bags, 500-1000 kg (1100-2200 lb) super sacks, or bulk pneumatic trailers for large-volume shipments.
• 存储建议: Store in a dry, covered area away from strong oxidizers. Shelf life exceeds 5 years under proper conditions.
• Handling Guidelines: Use appropriate PPE (gloves, dust mask) during transfer. Backwash new installations per manufacturer guidelines to remove fines and ensure optimal performance (e.g., initial soak for 16+ hours followed by graduated flow rates up to 18.5 gpm/ft²).
• Transportation: Non-hazardous per UN regulations; suitable for international shipping with HS Code 3802.10.

Safety Information

Wet activated carbon depletes oxygen in enclosed spaces—ensure adequate ventilation and follow confined space entry procedures. Non-flammable but may support combustion; avoid contact with strong oxidants. In case of dust exposure, rinse eyes/skin with water. Refer to SDS for full details. For emergencies, contact local authorities.
