Product Overview
PL-460 offers a pragmatic balance for applications where extreme purity isn't required but standard industrial grades carry too much ash risk. With ash content controlled below 460 ppm, this grade delivers significant purity improvement over conventional carbons (which typically run 5–15% ash) at a more accessible price point than ultra-pure grades like PL-390.
This is the carbon of choice for process engineers who've experienced ash-related problems—scaling, fouling, or product contamination—but can't justify the premium for maximum purity. It's also an excellent stepping stone for facilities upgrading their water treatment quality without a complete system overhaul.

Key application areas
- Industrial boiler feedwater — preventing scale and deposit formation
- Cooling tower makeup water — controlling cycles of concentration
- Process water for plating and coating — avoiding bath contamination
- Commercial laundry water — protecting fabrics and equipment
- Agricultural irrigation — removing contaminants that affect crop quality
Key advantage
PL-460 delivers measurable value through:
- 460 ppm Ash Ceiling: Achieves an order-of-magnitude purity improvement over standard columnar carbons without ultra-purity premium pricing
- Retained Adsorption Capacity: Moderate washing preserves micropore volume and surface area for robust organic removal
- Fixed-Bed Compatibility: 4 mm columnar extrusion ensures low pressure drop and uniform flow distribution in pressure vessels
- Batch Consistency: Tight process control limits ash variation lot-to-lot, reducing unexpected process upsets
