The blessed water of Zamzam goes through many stages, to take care and sterilize it according to the latest international technologies, and the General Presidency of the Affairs of the Great Mosque and the Prophet’s Mosque carries out maintenance work for the equipment and Zamzam devices. water stations on a regular basis, according to the pre-established preventive maintenance plan, which is supervised by an elite formed of engineers and technicians to ensure their quality before presenting them to the guests of the House of God of pilgrims and pilgrims, and to ensure their implementation in accordance with the technical principles followed and issue corrective work orders in the event of malfunctions and implement them immediately inside the stations.
The Assistant Director General for the Operation and Maintenance of Foreign Affairs of the Affairs of the Two Holy Mosques, Engineer Mishaal Al-Matrafi, spoke about the stages of sterilization and filtration of Zamzam water, and the equipment used during this which is considered to be the most recent in science. in this area, when the water passes through the latest sterilization systems (UV units) It is about killing bacteria and viruses with ultraviolet rays with a high level of sterilization, while a kilowatt of electricity sterilizes (12000) gallons of water, to ensure that Zamzam Water does not change color, taste or smell.
Regarding how ultraviolet rays are used in sterilization and filtering, Al-Mutrafi mentioned that it is the light energy produced from low pressure mercury lamps, protected by special types of glass. , which allows light to pass through bacteria, viruses and other microorganisms, penetrate the outer shell and destroy DNA[D. N. A].
He added: The water entered a cylindrical tube inside which there are lamps (lamps) that generate ultraviolet rays, and the number of lamps inside the cylinder depends on the size of the cylinder and the amount of water to be sterilized, and the rate of entry into the water is adjusted so that it is fast enough to kill bacteria or viruses.
In order to preserve the safety of Zamzam water, the Technical Affairs and Service Agency is taking a series of measures, starting with pumping Zamzam holy water from the Zamzam well in a closed circuit through filters. which trap sand and impurities and stainless steel pipes until they reach completely closed tanks, then pass the sterilization devices. Principle, and the same mechanism takes place when it is transferred to the Great Mosque by a team of specialists who supervise this work to ensure that the implementation is in accordance with the technical principles followed which meet the aspirations of the government of the Kingdom and their attention to the two holy mosques.
