Saudi Arabia uses nanotechnology to purify The Two Holy Mosques
The Saudi authorities have used nanotechnology to purify the holy sites, the Grand Mosque, the Prophet’s Mosque, and other sites, by photocatalysis of titanium dioxide activated in ultraviolet rays to kill microbes, remove odors and suspended organic materials.
The Custodian of the Two Holy Mosques Institute for Hajj and Umrah Research, according to what was published by the “Sabq” website, conducted a study on the feasibility of combating microbial pollution on the surfaces of the facilities of the Grand Mosque by making use of nanotechnology (nanomaterials) in self-and continuous disinfection of the surfaces of facilities.
The disinfection process begins by coating a nano-titanium dioxide material to reduce pollution and transmission of infection from toilets in the courtyards of the Grand Mosque, where titanium dioxide was used.
The study concluded that the nanotechnology of titanium dioxide has a significant effect in sterilizing the surfaces of toilets against bacteria in the long term from the coating of the material to the treated sites.
It has proven its resistance and stability to the procedures of daily hygiene work.
The study also recommended the use of nanotechnology as a disinfectant for the surfaces of toilets in the long term and the rest of the surfaces of other facilities such as walls, coverings of the Kaaba, mattresses, and containers.
