PSD-A1
purestar
Manufactured from select high-density coconut shells through carbonization and extended steam activation, PSD-A1 12×40 is a high-purity coconut shell granular activated carbon with an iodine number exceeding 1100 mg/g and a surface area greater than 1000 m²/g. This micropore-dominant structure delivers reliable adsorption capacity for trace organic contaminants, residual chlorine, and taste- and odor-causing compounds in demanding water treatment environments.
With low ash content (<5%), controlled pH (8–11), and exceptional mechanical strength (>95%), PSD-A1 maintains consistent hydraulic performance and minimal fines generation under repeated backwashing and long-term bed operation. NSF 61 certified and approved for food and drinking water contact, it is engineered for point-of-entry (POE) treatment, semiconductor ultra-pure water systems, condensate polishing, and food & beverage processing where media purity and operational reliability are essential.
