Technical Advantages

Ultra-High Purity & Superior Adsorption Kinetics

Sourced from select Southeast Asian coconut shells, our premium coconut shell activated carbon features micropore-dominant structures with iodine values reaching 1000-1500 mg/g.

The low ash content (<3%) and exceptional purity make it the preferred choice for semiconductor ultra-pure water systems, gold recovery (CIP/CIL/CIC processes), and food-grade decolorization.

High mechanical strength (>95%) ensures minimal attrition during backwashing, while the developed surface area (1000-1500 m²/g) provides rapid adsorption kinetics. Available in granular, columnar (PLC), and silver-impregnated (PSD-Ag+) variants for antimicrobial water treatment applications.

FAQ

Q1: What is the difference between PSD-A0 S and standard acid-washed carbon?

A: PSD-A0 S undergoes extended acid washing with quality-controlled rinse cycles, achieving 50-75% lower extractables than single-wash products.

Q2: Is PSD-A0 S certified for nuclear applications?

A: PSD-A0 S can be supplied with full traceability documentation and testing per nuclear industry specifications. Contact us for nuclear-grade certification requirements.

Q3: What is the recommended rinse procedure before service?

A: Rinse with 10-15 bed volumes of high-purity water until effluent resistivity and TOC meet system specifications.

Q4: Can PSD-A0 S be regenerated?

A: While technically possible, regeneration of nuclear/semiconductor grade carbon is rarely practiced due to contamination risks. Evaluate economics versus virgin replacement.

Q5: What packaging options prevent contamination?

A: PSD-A0 S is available in nitrogen-purged polyethylene-lined drums or specialized clean-room packaging for critical applications.
