Photocatalytic activated carbon

Part No.
KDX
Photocatalytic activated carbon

"Suction power" of activated carbon and "decomposing power" of titanium oxide

Photocatalyst
When exposed to sunlight, reactive oxygen is generated by the action of the titanium oxide photocatalyst, resulting in an antibacterial and antifungal effect.
Suction power
Draws fine particles and fungi via attraction to the activated carbon, which increases the photocatalyst effect.
Safety
Eco activated carbon and titanium oxide are highly safe as they are included in the food additives list.

Features

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 site of water in contact with activated carbon and hit by sunlight. Removal of fountain and other water blooms.
