Residents of Tarazona, Novalas, Torreras and Los Fayos in the province of Zaragoza were unable to drink tap water, cook with it or brush their teeth for weeks after the emergence of Cryptosporidium parvum, resulting in The epidemic broke out. Gastroenteritis has been detected in the Quailes River and has affected more than 500 people, most of whom had mild illness.
After many days of headaches and inconvenience to neighbors, it’s now certain that The parasite that caused the Qarthen contamination did not originate in Aragorn; But it exists in the area where the Vozmediano fish farm in Soria is located. The Ministry of Health of the Government of Aragon made the statement last Monday based on the results of an analysis of the vaccines collected last Tuesday at three different sites in the first district of Quiles, in the neighboring community of Castile and León.
Short- and medium-term solutions are on the table so that oral water contamination is not repeated in the future. The DGA is studying the installation of UV systems at water treatment plants in the four cities. so, What does this process consist of? Is it harmful to health?
Ultraviolet (UV) light is a proven and increasingly popular alternative It is prohibited to use chemical products to disinfect drinking water, wastewater and industrial water of all water qualities. Microbial contaminants can be removed from water using chemicals such as chlorine: using a very tight filter, such as a ceramic filter, or using UV light to completely inactivate viruses and bacteria.
What is UV rays?
This radiation has a shorter wavelength than visible light but longer than X-rays, with a wavelength between 400 and 100 nm (nanometers). The most common source of UV radiation is the sun, Although it can also be done artificially using UV light.
The use of ultraviolet light to disinfect water is nothing new, as the germicidal properties of sunlight were known as early as 1877. In fact, as it seems, treating water with UV light does not kill bacteria and viruses; Changing their DNA so they can’t reproduce and lose their infectivity.
DNA is present in the molecular core of all microorganisms (bacteria, viruses, fungi, and cysts), and its property of absorbing UV radiation damages the amino acid chains of proteins, causing metabolic disorders and affecting their reproductive mechanisms. , Thereby achieving its inactivation and eliminating its properties of disease-producing and microbial growth.
Additionally, one of the main benefits of using UV light for disinfection is No chemicals of any kind are used for it. Rather, it is a physical treatment that does not require the storage of any hazardous chemical products.
How do these lights work?
Artificially generated ultraviolet rays are produced by A pure quartz emitter (lamp), containing an inert gas, is responsible for providing the initial discharge. As electrical energy increases, the heat generated by the emitter also increases as the internal pressure of the gas increases, thereby exciting electrons that pass through lines of different wavelengths, producing ultraviolet light. Low voltage discharge produces spectra at 185 and 253.7 nm. Medium-pressure UV emitters produce multiwave radiation, i.e. different wavelengths with varying intensities across the entire UV-C spectrum (200-300 nm).
What are your main benefits?
ultra violet light They do not change the properties of the treated water or have any dangerous or negative effects on it. In case of overdose. Additionally, they are a simple and inexpensive solution for facility maintenance.
It installs easily on existing water pipes and treats water for its intended purpose such as human consumption, industrial processes, laboratories or agriculturewait.
Finally, these lights are compatible with other processes, such as ozone generators.
