PSD-MAC Catalytic Coconut Shell Carbon – Chloramine & Hydrogen Peroxide Decomposition

PSD-MAC is a catalytic-grade coconut shell activated carbon produced from premium Southeast Asian coconut shell raw material through a specialized surface-modifying activation process. It combines conventional physical adsorption with enhanced surface catalytic activity, delivering dramatically improved removal efficiency for chloramines, refractory chlorates and residual hydrogen peroxide compared to standard adsorption-only activated carbons.

Product Overview

Conventional activated carbon removes free chlorine rapidly but struggles with combined chlorine (chloramines), which require much longer contact times and often break through prematurely in real-world systems. PSD-MAC solves this limitation through a high-temperature gas treatment process that modifies the carbon surface electronic structure, creating highly active catalytic sites that actively decompose chloramine molecules rather than relying solely on physical adsorption.

This dual-function design maintains full conventional adsorption capacity for organics, taste and odor compounds while adding catalytic decomposition capability. It also efficiently breaks down residual hydrogen peroxide from industrial oxidation processes, providing a chemical-free, clean treatment solution. With an iodine value above 1000 mg/g and ≥90% hardness, it delivers reliable long-term performance in both municipal waterworks and residential filtration systems.

Key Features

Dual-action adsorption + catalytic decomposition
Combines standard organic adsorption with active catalytic breakdown of chloramines, chlorates and hydrogen peroxide for broader contaminant coverage.
Superior chloramine removal efficiency
Significantly outperforms standard activated carbon for combined chlorine removal, addressing the most common modern municipal water taste and odor issue.
Impregnant-free catalytic surface modification
Catalytic activity is created through thermal surface modification, with no chemical impregnants added, eliminating risk of secondary chemical leaching.
Premium low-ash coconut shell substrate
Manufactured from high-density Southeast Asian coconut shell with low inherent mineral content, minimizing extractables in treated water.
Proven peroxide decomposition performance
Rapidly catalyzes hydrogen peroxide breakdown into water and oxygen, making it suitable for post-oxidation polishing in industrial water systems.

Applications

Chloramine Breakthrough in Municipal Water: Municipalities increasingly use chloramines for secondary disinfection, but standard activated carbon struggles with combined chlorine—requiring long contact times and breaking through prematurely. PSD-MAC's catalytic surface actively decomposes chloramine molecules rather than relying solely on physical adsorption, delivering extended service life in chloramine-heavy water.
Hydrogen Peroxide Residual Removal: Industrial oxidation and sanitization processes leave residual H₂O₂ that can damage downstream equipment. PSD-MAC's catalytic surface decomposes peroxide into water and oxygen without chemical additives, providing clean post-oxidation polishing.
Residential Whole-House Chloramine Treatment: Homes served by chloramine-disinfected water experience taste/odor issues. PSD-MAC provides far better chloramine removal than standard GAC filters, extending filter change intervals.
Food & Beverage Process Water: Chloramines and oxidative residuals negatively affect product flavor, color and fermentation. PSD-MAC removes these contaminants without introducing secondary chemicals.
