8×30 Coconut Shell Carbon
for Municipal Water

Engineered for large-scale water treatment. Low pressure drop, extended bed life, superior hardness for thermal reactivation. The workhorse GAC for city water plants.

Built for Large-Scale Water Treatment

Municipal water plants need a GAC media that handles high flow rates without excessive head loss, survives repeated backwash cycles, and can be thermally reactivated multiple times. Our 8×30 coconut shell carbon is designed precisely for these demands — the larger particle size compared to 12×40 reduces pressure drop by 40–60% while maintaining excellent adsorption capacity.

The uniform particle size distribution (UC ≤1.7) ensures consistent flow distribution across the bed, preventing channeling that degrades treatment performance. High ball-pan hardness (≥97%) means minimal carbon fines in the treated water and excellent recovery rates during thermal reactivation — a critical economic factor for large plants managing 50–500+ tons of GAC inventory.

Frequently Asked Questions

Why 8×30 mesh for municipal water?
8×30 is the preferred mesh for large-volume GAC contactors and pressure filters. The coarser particle size produces significantly lower head loss (pressure drop) compared to 12×40, allowing higher flow rates and longer filter runs between backwashes. This translates directly to lower operating costs for municipal plants.
How does 8×30 compare to 12×40 for water treatment?
8×30 offers lower pressure drop and longer bed life at the expense of slightly slower adsorption kinetics. For large gravity contactors with 10–20 minutes EBCT, the difference in removal efficiency is minimal. 8×30 is standard for new municipal installations; 12×40 is preferred for smaller POU systems where contact time is limited.
What is the typical bed life in a municipal plant?
At 5 gpm/ft² loading rate with 15-minute EBCT, our 8×30 coconut GAC typically provides 2–4 years of service for taste and odor control. For TOC removal targeting <2 mg/L, expect 12–24 months depending on inlet TOC levels and seasonal variations.
Can this carbon be thermally reactivated?
Yes. Coconut shell 8×30 GAC is well-suited for thermal reactivation at 800–900°C. Typical recovery is 90–95% by weight with 5–8% capacity loss per cycle. The high hardness (≥97%) minimizes size degradation during reactivation and transport.
What is the MOQ and delivery format?
MOQ is 5 tons for 8×30 municipal grade. Standard packaging: 1-ton super sacks (most common for water plants) or 25 kg bags on pallets. Containerized shipment (20 MT/20ft container). Lead time 10–15 days FOB China.
