Photocatalytic Treatment Removes Pollutants from Car Park
Car parks and road tunnels are two environments where air pollution significantly affects the users of these infrastructures as well as the people working there. Pollutants mainly come from vehicle exhaust and can also be conveyed into the car park from the surrounding area. Treating the appropriate surfaces in a tunnel or car park with photocatalytic materials enables significant reduction of the air pollution. Photocatalytic materials have other functionalities that provide added value to these infrastructures. Being hydrophilic, a photocatalytic surface is cleaned more easily than a regular one. The antibacterial effect reduces the formation of mold and helps in keeping the coated surfaces cleaner for longer periods.
CristalACTiV™ technology was tested in representative field test trials to confirm the laboratory findings on the developmental products. A trial using paint from Pacific Paints (Boysen), containing CristalACTiV photocatalyst was conducted in a car park in Manila, Philippines.
