Fading of colored components in livestock wastewater and antibacterial performance! Introduction to tests conducted at the Kyoto Prefectural Livestock Research Institute.

We will introduce the performance of the liquid-phase reaction system of the photocatalyst "Titanistar." ■ Decolorization of colored components in livestock wastewater - Testing institution: Kyoto Prefectural Livestock Research Institute We conducted tests to decompose colored water components treated by the activated sludge method provided by the Kyoto Prefectural Livestock Center using Titanistar. We selected pure titanium mesh material and applied the MI-C type of Titanistar's liquid-phase reaction system for the test sample. The ultraviolet intensity was set at BLB 1mW/cm², and the decolorization of the colored water was measured using a color difference meter. The results showed that as the irradiation time increased, the water components gradually decomposed and became lighter. *For more details, please download the PDF or feel free to contact us.

basic information

What is the photocatalyst "Titanistar"? It is not a coating-type photocatalyst, nor does it use any of the raw materials typically employed in such products. It generates a titanium dioxide photocatalytic film on the surface of pure titanium by simply performing surface oxidation treatment on the titanium within pure titanium metal. This film contains no impurities and is generated without any interface with pure titanium. It is characterized by high photocatalytic ability and a highly durable film. ■ Antibacterial Performance Testing Institution: Kyoto Microbiological Research Institute Antibacterial performance tests were conducted against Escherichia coli, Staphylococcus aureus, and Bacillus subtilis. Titanium plates treated with MI-W from the gas-phase reaction system and MI-C from the liquid-phase reaction system of the Titanistar series were prepared as test samples, while untreated titanium plates served as blanks. After preliminary irradiation with BLB 1mW/cm², the tests were conducted using the film adhesion method. As a result, we confirmed that the viable bacterial counts for various Titanistar types showed such high antibacterial performance that they were undetectable. *For more details, please download the PDF or feel free to contact us.
