PSD-A0 Coconut Shell Granular Carbon – NSF 61 Certified for Drinking Water

Key Features

• NSF 61 Certified Drinking Water Safety

  Independently certified to NSF/ANSI 61 standards for potable water system components, ensuring extractable contaminants remain well below regulatory limits for safe drinking water and food-contact applications.

• High Iodine Adsorption Capacity

  Highly developed micropore structure delivers strong removal of free chlorine, dissolved organics, taste and odor compounds, and disinfection byproducts across typical municipal and process water quality ranges.

• Ultra-High Mechanical Durability

  Exceptional abrasion resistance minimizes particle attrition during hydraulic backwashing and continuous operation, maintaining stable bed permeability and long service life in pressure filter vessels.

• Low Ash & Minimal Extractables

  Refined coconut shell base with controlled ash content reduces soluble mineral leaching and secondary contamination risk, making it ideal for ultrapure water pretreatment and sensitive food processing environments.

• Stable pH & Bulk Density Performance

  Natural alkaline pH and consistent particle density ensure predictable hydraulic behavior, efficient bed packing, and reliable pressure drop characteristics across diverse filtration system configurations.

Applications

• Municipal & POE Water Taste & Odor Compliance: Standard coal-based carbon can introduce ash and mineral leachables that affect water taste and safety. PSD-A0's NSF/ANSI 61 certified coconut shell base naturally delivers lower ash and superior taste/odor improvement, ensuring potable water compliance without the secondary contamination risks of lower-grade media.

• Semiconductor UPW Pretreatment: RO membranes and EDI modules are vulnerable to chlorine and organic fouling. PSD-A0's ≥1000 mg/g iodine value provides reliable dechlorination and organic removal, extending downstream equipment life at a lower cost than premium acid-washed grades.

• Food & Beverage Process Water Consistency: Breweries and food plants require water that won't alter product flavor. PSD-A0's coconut shell structure removes chlorine and odor compounds more effectively than coal carbon, supporting batch-to-batch taste consistency.

• Power Plant Condensate Polishing: Condensate systems need consistent organic removal without heavy mineral leaching. PSD-A0's low inherent ash makes it suitable for pre-polishing stages where standard coal carbon would contribute inorganic contaminants.

Technical Advantages

• NSF/ANSI 61 certified drinking water safety with independent testing ensuring extractable contaminants remain below regulatory limits.

• Naturally lower ash and better taste/odor improvement compared to coal-based carbons for food and drinking water applications.

• Optimized pore size distribution provides fast adsorption kinetics and high usable capacity under design flow rates.

• Complete regulatory certification package simplifies customer audit and regulatory compliance in food, beverage and drinking water markets.

FAQ

Q: What is the main difference between PSD-A0 and PSD-A0 S?

A: PSD-A0 is the standard untreated grade with pH 8–11, ideal for general pretreatment and food process water. PSD-A0 S is the acid-washed variant with <3% ash and neutral pH, engineered for high-purity water systems where minimal metal leaching is critical. For the highest purity, consider LC-A0.

Q: Is PSD-A0 suitable for under-sink POU filters?

A: PSD-A0 is approved for drinking water contact and works well for POE whole-building systems. For point-of-use end-of-tap applications requiring the lowest extractables, we recommend upgrading to PSD-A0 S or PSD-A1 S.

Q: Should I choose PSD-A0 or coal-based GAC for drinking water treatment?

A: PSD-A0 coconut shell carbon offers lower ash (<5%), higher hardness (>95%), and NSF 61 certification — making it preferred for drinking water, beverage, and food process applications. For large-volume municipal or industrial pretreatment where cost efficiency is the priority, coal-based GAC-P or WT-S provide economical alternatives with comparable organic removal capacity.
