How UV disinfection works ?

How UV disinfection works ?

In 1877 scientists first observed strong sunlight disinfecting water. They noticed that sugar water kept in the shade went cloudy as microorganisms grew in it, whereas the sugar water kept in direct sunlight stayed totally clear. Being able to artificially create the correct wavelengths of UV light with lamps gives us the power to disinfect a variety of liquids as well as air and surfaces.

UV disinfection (also known as ultraviolet germicidal irradiation) is a chemical-free disinfection method that uses short-wavelength ultraviolet (UV-C) light to kill or inactivate microorganisms by disrupting their DNA, leaving them unable to perform vital cellular functions such as reproduction. At the 254nm wavelength UV light can penetrate the cell wall of a microorganism, permanently altering the DNA structure within seconds and leaving no chemical by-products as a result.

Precise and targeted ‘dosing’ is used to calculate the type of lamp needed for different applications and how long different liquids, air or surfaces need to be exposed to the UV light, in order for them to be safely disinfected.

Dosing takes into account the UV intensity being given out from the lamps, the UV transmittance (UVT) of the water, air or surface (if applicable) and the amount of time the substance being disinfected is exposed to the UV light.

Advantages of UV disinfection

Advantages of UV disinfection

UV disinfection has many advantages over conventional methods for surface, air and water disinfection:

The majority of UV disinfection systems require no chemicals, just correct application of the germicidal lamps – depending on the application some processes may still use chemicals, but in much smaller amounts

There are no toxic chemical or carcinogenic by-products left behind when UV disinfection is used

UV disinfection systems are often smaller and easier to use than conventional systems, with affordable capital and operational costs.

UV disinfection doesn’t alter the taste of liquid or food, which can happen with chemical or heat treatments

UV disinfection systems are often safer for the personnel using them than chemical systems, and eliminating the need to produce, store and transport dangerous and potentially toxic chemicals

Germicidal lamps are equally effective against bacteria, moulds, spores, bacteria and viruses.

UV disinfection inactivates pathogens which have developed a resistance to chlorine and other chemicals, such as cryptosporidium.

Glossary of terms

Amalgam lamps: low-pressure germicidal UV lamps containing an alloy of mercury with other metals.

Aquatics: refers to water parks, swimming pools, hydro pools and water features or fountains.

Aquaculture: refers to the large-scale breeding and raising of fish, shellfish and crustaceans for zoos, aquariums and the food industry.

Ballast water: is the large volume of water pumped into tanks in ocean-going shipping vessels, cruise ships and military vessels to allow them to balance loads and ensure stability at sea.

Biocide: refers to a poisonous substance, for example a pesticide

Chlorine: one of the most commonly used chemicals for water disinfection, chlorine kills pathogens such as bacteria and viruses by breaking the chemical bonds in their molecules.

Chloramines: chemicals which can be used as a secondary disinfection method in municipal water distribution systems.  In swimming pools, chloramines are formed by the reaction of free chlorine with organic substances, such as urine and sweat.

Dechlorination: removing residual chlorine from disinfected wastewater prior to discharge into the environment

Dose: dosing takes into account the UV intensity being given out from the lamps, the UV transmittance (UVT) from the water, air or surface (if applicable) and the time of exposure to UV light.

DNA: DNA (deoxyribonucleic acid) is the complex chemical that carries genetic information. DNA is contained in chromosomes, which are found in the nucleus of most cells.

Dwell time: the time a liquid, surface or air is exposed to a disinfectant, for example time a food conveyor belt may spend under a germicidal UV lamp.

Electromagnetic spectrum/radiation: the entire range of all possible electromagnetic radiation. This includes gamma rays, X-rays, ultraviolet, visible light, infra-red, microwaves and radio waves.

Electronic ballasts: specially-designed power supplies that will unsure long UV lamp life with consistent output.

Elemental (metallic) mercury: one of the three chemical forms of mercury, which usually causing health effects when inhaled in vapour form. Exposures can occur when elemental mercury is spilled or products that contain elemental mercury break and expose mercury to the air, particularly in warm or poorly-ventilated indoor spaces.

Germicidal lamps: a generic description for a UV lamp designed to emit radiation at a wavelength that will inactivate micro-organisms by disrupting their DNA

Flow rate: measurement of water passing through a UV disinfection or oxidation system. Examples of measurement metrics include m₃/hour or gallon/minute

Horticulture: the study and production of plants

Hydroponics: a method of growing plants without soil, using mineral nutrient solutions in a water solvent

Inactivation (of microorganism): referring to the action of impeding a microorganism’s ability to survive under given conditions

Intensity: the overall power output of a UV, often designated in watts

Low pressure UV lamps: germicidal UV lamps with low mercury vapour pressure, used for disinfection

Medium pressure UV lamps: UV lamps with medium mercury vapor pressure, used for germicidal and curing applications

Microorganism: a microscopic organism which can be single-celled or multi-celled, include all bacteria, archaea and most protozoa. Some fungi and algae are also classed as microorganisms. .

Municipal: of or relating to a town/city or its government

Nanometre (nm): a unit of spatial measurement that is 10-9 meter, or one billionth of a meter.

Noble Gases: chemical elements in Group XVIII of the periodic table with similar properties such as being odourless, colourless and of low reactivity. This includes helium, neon, argon, krypton, xenon and radon.

OEM: Original Equipment Manufacturer. For example a UV disinfection OEM may be a company manufacturing the complete UV disinfection system.

Oxidation: chemical treatment procedures using UV and hydroxyls to remove organic (and sometimes inorganic) materials in water

Pasteurisation: methods of treating liquids to ensure they are safe for human consumption – for example heating milk to very high temperatures

Pathogen: a bacterium, virus, or other microorganism that can cause disease.

Quartz Sleeve: used to house the UV germicidal lamps, providing protection against  damage,  leakage, temperature fluctuations and water.

Wastewater reuse: reusing treated wastewater for beneficial purposes such as agricultural or landscape irrigation, industrial processes or toilet flushing

Wavelength: refers to the distance between consecutive corresponding points of the same phase of a wave.

Ultrapure water: ultrapure water (also UPW or high-purity water) is water that has been purified to very stringent specifications for pharmaceutical, microelectronic and laboratory processes.

UVA: also known as “Longwave UV”. UVA has a wavelength range of 400 — 315 nm. It is the least harmful of the three UV wavelengths but can still contribute to the ageing of skin, DNA damage and possibly skin cancer. UVA lamps are used for curing of inks, adhesives and coatings and specifically; screen printing and flexo printing.

UVB: also known as “Midwave UV” or “Medium Wave UV”. UVB has a wavelength range of 315 – 280 nm. It is more dangerous than UVA and is responsible for burning the skin among other things. In industry UVB lamps are used for curing of inks, adhesives and coatings and specifically clear coatings and thin ink layers.

UVC: also known as “Shortwave UV”. UVC has a wavelength range of 280 – 100 nm. It is the most harmful and highest energy of the three UV wavelengths. In industry UVC is used for water and air disinfection as it can render micro-organisms harmless.

UV Intensity: measures the “amount” of UV energy that comes into contact with the air surface or water being treated.

UV LEDs: light-emitting diodes (LEDs) can be manufactured to emit light in the ultraviolet range, some of which are used for UV disinfection.

UV Transmittance: this is the measure of UV energy at a particular wavelength or frequency after it has been passed through a solid (i.e. quartz) or a liquid.
