Product Overview
PSD-A0 S represents our flagship coconut shell activated carbon series, engineered specifically for applications where purity is non-negotiable. Sourced from select Southeast Asian coconut shells and refined through a proprietary steam activation and acid-washing process, this granular carbon delivers consistent performance in the most demanding environments.
Unlike standard water treatment carbons, PSD-A0 S undergoes an extended activation cycle that develops an optimized pore structure—balancing micro, meso, and macro pores for versatile contaminant removal. The "S" designation signals our premium select grade with tighter quality control and lower extractable impurities.

Key Application Areas
- Semiconductor ultra-pure water (UPW) systems — removes TOC, particles, and trace organics without introducing contaminants
- Point-of-entry (POE) and point-of-use (POU) residential water treatment
- Food and beverage processing — meets FDA and HALAL requirements for direct contact applications
- Condensate polishing in power generation
- Electroplating solution circulation systems
Key advantage
- Raw Material Integrity: We trace every batch back to specific coconut plantations, ensuring consistent shell density and carbon content
- Low Ash, Low Metals: Acid-washing reduces ash content to under 3% and minimizes leachable metals—critical for electronics-grade water
- High Mechanical Strength: >95% hardness rating means less fines generation during backwashing, extending filter runs and reducing operational headaches
- PH-Neutral Performance: The 5–8 pH range ensures minimal impact on treated water chemistry
