PSD-A1
purestar
PSD-A1 granular activated carbon is produced from hand-selected coconut shell through precise carbonization and steam activation. The manufacturing process is optimized to minimize water-soluble organics and total organic carbon (TOC) release.
The product exhibits high iodine value (>1000 mg/g), exceptionally low ash content (<3%), and consistent 8×20 mesh particle size. Designed for point-of-entry (POE) and point-of-use (POU) systems in semiconductor fabs, beverage production, and pharmaceutical water systems where TOC control is critical.

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.

Q1: What makes PSD-A1 suitable for semiconductor applications?
A: PSD-A1 is manufactured with strict process controls to minimize TOC release and soluble silica - critical contaminants in semiconductor rinse water and chemical baths.
Q2: How does PSD-A1 differ from standard coconut shell carbon?
A: PSD-A1 uses premium raw material selection and enhanced quality control to achieve lower extractable levels than standard grades, meeting the stringent requirements of UPW systems.
Q3: What is the recommended pre-treatment before use?
A: Initial rinse with DI water until effluent TOC stabilizes (<100 ppb) is recommended before placing in service.
Q4: Can PSD-A1 remove dissolved silica?
A: Activated carbon does not effectively remove dissolved silica. For silica control, ion exchange or specialized adsorbents are required upstream.
Q5: What is the maximum operating temperature for PSD-A1?
A: Continuous operation up to 50°C is recommended. Higher temperatures may increase TOC release and reduce adsorption capacity.
