Technical data sheet & illustrative COA reference · Irregular granular activated carbon
Coal Based Granular Activated Carbon
Coal based GAC with configurable mesh, iodine value, CTC, hardness and washing options for industrial filtration and adsorption beds.
- Balanced micro- and mesoporous pore network derived from selected Ningxia anthracite and bituminous coal blends, ideal for high-molecular-weight organics, COD, color bodies, and municipal/industrial water beds.
- Supplied in 8x30, 12x40, 8x16, and 4x8 mesh with 800–1,050 mg/g iodine value (ASTM D4607), 120–200 mg/g methylene blue, and high wetting density (450–550 g/L) for stable backwash bed stratification.
- Cost-effective bulk alternative to international agglomerated coal GAC grades with 10,000+ MT/year factory capacity, 25 kg or 500/1,000 kg FIBC export packaging, and full ASTM COA verification.

3Grading & operating references
Confirm the mesh grade before ordering. Listed only in standard sizing: 12x20, 12x30, 20x40, 30x60, 4x8, 6x12 mesh. Listed only in the detailed grading table: 12x40, 8x20 mesh. These references do not list the same mesh grades. Confirm the required sieve distribution, retaining screen and acceptance limits with your quotation.
