Decompose & Purify with the Power of Light

Photocatalytic Activated Carbon (KDX) (Trade Name: CRI-up®) is a composite functional activated carbon that combines high-quality coconut shell activated carbon, excellent in adsorption, with titanium oxide photocatalyst, which generates active oxygen upon light irradiation. It simultaneously leverages the physical adsorption of activated carbon and the decomposition action of titanium oxide to provide environmental functions such as antibacterial, anti-mold, and water quality improvement.

Features

Hybrid Effect of Adsorption and Decomposition
Activated carbon adsorbs fine particles and fungi, while titanium oxide generates active oxygen (e.g., OH radicals) under light irradiation. This chemically decomposes and detoxifies adsorbed pollutants.
Antibacterial and Anti-Mold Performance
The photocatalytic action suppresses the proliferation of bacteria and mold. It is suitable for long-term use in outdoor and humid environments.
Environmentally Friendly and Highly Safe Design
Titanium oxide is highly stable, does not leach additives, and can be safely used in water contact applications.

UES photocatalytic activated carbon (Trademark: CRI-up®) is an activated carbon in which titanium oxide is integrated into coconut shell activated carbon with superior adsorption action.
Photocatalysts release reactive oxygen through sunlight, which results in an antibacterial and antifungal effect (US PAT acquired, US 6,673,738 B2)

Application

Water Purification Applicationsf

It is utilized to suppress the growth of algae (e.g., Aoko) and microorganisms in water contact environments exposed to sunlight (e.g., ponds, fountains, waterways).
