Activated Carbon (GAC 8×30)

Description

1. Product Overview

Activated Carbon (GAC 8×30) is a high-density, granular activated carbon manufactured from select-grade bituminous coal, precision-sieved to the 8×30 U.S. mesh standard. It is primarily used in large-scale liquid-phase purification, including potable water treatment, wastewater remediation, and industrial process decontamination. The key value proposition lies in its exceptional hardness and optimized pore distribution, delivering superior adsorption capacity and minimal fines generation over extended service cycles. Strategically, this product is critical for industries facing tightening environmental regulations and the need for reliable, high-purity output, making it a cornerstone asset in mission-critical filtration infrastructure.

2. Key Specifications & Technical Characteristics

• Chemical Composition: High-activity bituminous coal-based carbon, >90% fixed carbon

• Purity Level: Premium industrial grade; low ash content (≤8%) and minimal leachable inorganics

• Physical Characteristics:

  • Form: Granular, irregular particles

  • Color: Black

  • Particle Size: U.S. Mesh 8×30 (0.6 – 2.36 mm); effective mean size ~1.2 mm

  • Apparent Density: 480–520 kg/m³

  • Iodine Number: ≥1000 mg/g (minimum)

  • Abrasion Resistance (Ball Pan Hardness): ≥97%

• Packaging Options: 25 kg multi-wall paper bags, 500 kg FIBCs (big bags), or bulk pneumatic tanker

• Shelf Life: 3 years in original unopened packaging stored in dry, non-odorous conditions; no degradation in adsorption performance if kept dry

3. Core Industrial Applications

• Primary Industries: Municipal water treatment, industrial wastewater (chemical, petrochemical, textile), food & beverage processing, pharmaceutical manufacturing, and groundwater remediation.

• Specific Operational Use Cases:

  • Removal of organic contaminants, chlorine, chloramines, taste, and odor compounds

  • Polishing of reverse osmosis permeate and dechlorination before membranes

  • VOC (volatile organic compound) capture in fixed-bed contactors

• Performance Superiority: The 8×30 mesh size achieves an optimal balance between pressure drop and adsorption kinetics—larger than 12×40 for lower head loss, yet finer than 6×12 for faster mass transfer. High abrasion resistance reduces operational losses during backwashing, extending bed life by 15–20% compared to standard GAC grades.

• Efficiency/Cost Advantage: Lower regeneration frequency and reduced fines carryover mean lower total cost of ownership (TCO) over a 3–5 year facility cycle.

4. Competitive Advantages

• Quality Consistency: ISO 9001:2015 certified production with lot-to-lot statistical process control; each batch tested for iodine number, hardness, and mesh distribution.

• Supply Reliability: Dedicated manufacturing lines with 5,000 MT monthly capacity; safety stock maintained in regional hubs (Americas, EMEA, APAC) ensuring <10-day lead times for standard orders.

• Logistics Capability: Direct container loading and break-bulk options with fumigation-compliant packaging for international shipment.

• Price Competitiveness: Tier-1 performance at 12–18% below average market price for equivalent NSF-certified alternatives, due to vertically integrated coal sourcing.

• Sustainability & Technical Support: 100% coal-based carbon with re-activation service available; full documentation including MSDS, product data sheets, and application engineering support (bed depth calculators, breakthrough curves).

5. Commercial & Supply Information

• Minimum Order Quantity (MOQ): 20 metric tons (MT) – one full 20ft container equivalent

• Loading Capacity (MT per container):

  • 20ft standard dry container: 20 MT (palletized in FIBCs or bags)

  • 40ft container: Not recommended for this density; maximum 20 MT due to weight limits

  • Bulk pneumatic tanker (road/rail): 22–25 MT per load
