Panasonic Launches Photocatalytical UV Water Purification
Published on by Water Network Research, Official research team of The Water Network in Business
The System Relies on Photocatalytical Compounds and UV Light to Remove Toxic Substances Including Arsenic, Hexavalent Chromium, Bacteria and Various Agricultural and Pharmaceutical Residues from the Water
Capable of removing dangerous pollutants from water at high speed, the technology was introduced at the recent Eco Products trade show in Tokyo.
The system relies on photocatalytical compounds and UV light to remove toxic substances including arsenic, hexavalent chromium, bacteria and various agricultural and pharmaceutical residues from the water.
Panasonic has used titanium dioxide as a photocalyst, distributed in extremely fine particles. When exposed to ultraviolet rays, the photocatalyst forms reactive oxygen molecules to bind the contaminants.
Though highly efficient, the method was previously considered impractical due to the difficulty in subsequent removal of such tiny grains from the cleaned water.
However, Panasonic designed an improvement in the system by binding titanium oxide to zeolite. Unlike other approaches, this technique doesn't reduce the activity of the titanium oxide particles.
Moreover, since the two particles are bound together by electrostatic force, there is no need for binder chemicals.
The company wants to build water-purification trucks equipped with the system that could be conveniently driven to areas in need of safe, drinkable water. Eventually, local water supply operators in developing countries could use the system in water treatment facilities.
