How Does UV Light Kill Bacteria?

Ultraviolet (UV) light kills bacteria in many air, surface and water sterilization applications with proven effectiveness.  UVC radiation instantly kills bacteria, viruses and harmful contaminants within seconds of exposure with emitted at the powerful wavelength of 254 nanometer (nm).  UV light is measured in wavelengths referred to as nanometers, with 254 nm the most powerful UVC radiation to eradicate harmful contaminants. UVC radiation instantly penetrates the cells of these microorganisms, damaging the nuclei of harmful cells to render them unable to replicate and spread disease.

UV light emitted in the range of UVC wavelengths at 254 nm instantly kills bacteria, viruses, and harmful contaminants on surfaces, in water and in the air.   UV radiation effectively eradicates volatile organic compounds (VOCs) including mold spores, mildew, fungi and many other microscopic invaders even those naked to the human eye.  UVC germicidal lamps provide clean and safe air and water in many applications, including residential homes, businesses and industrial applications.

UV radiation is safe and effective, providing clean, purified and sterilized air in many commercial environments such as schools, doctor offices, hospitals, nursing homes and medical facilities.  This is especially important for people with compromised immune systems who may be at risk of contracting disease and illness through airborne contaminants and harmful germs.

Phototherapy Treats Seasonal Depression


Seasonal depression often occurs during the fall and winter months for people who live in the Northern Hemisphere, when daylight hours begin to diminish.  If you experience seasonal depression, also referred to as Seasonal Affective Disorder (SAD), you should talk to your physician about therapies including light therapy.  Light therapy is also called phototherapy and is successful in treating anywhere from 50% to 80% of patients when administered properly.

If you experience any of the following symptoms of seasonal depression, consult with your physician about light therapy for depression.  Symptoms of seasonal depression include:

    • Social withdrawal
    • Craving foods which are high in carbohydrates
    • Loss of interest in normal activities
    • Excessive fatigue
    • Weight gain

Phototherapy is recognized as effective therapy SAD, making a considerable improvement in the mood of at least 50% of patients undergoing treatment.  When light therapy is administered to an individual’s specific wake and sleep cycle, the percentage of successful treatment increases to as much as 80%.  Light therapy usually consists of 30 minutes of exposure from a white fluorescent light each morning. Most patients see a remarkable improvement within as little as one week of treatment.

Effective Ballast Water Treatment Methods

post 82

With the most recent regulations for the Ballast Water Treatment Convention taking effect last fall of 2017, all ships are required to have an approved ballast water treatment system on board their vessel.  When ships use ballast water while traveling through international waters, they take on ocean water in one port and release it in another. This transfer of ballast water is viewed as one of the largest threats to our planet’s oceans.

When ships release water from one port into a foreign port, aquamarine microorganisms including dangerous bacteria, viruses and foreign life forms often invade the new port with catastrophic results.  Invading species are free to take hold in new waters without their natural predators and will often replicate uncontrollably shutting down fishing ports and devastating entire towns. Once thriving fishing town are turned into ghost towns leaving the waters contaminated and the human population without a livelihood.  

The Marine Environment Protection Committee (MEPC) is a subsidiary of the International Maritime Organization (IMO) and enforces the new Ballast Water Treatment Convention (BWTC) which sets the standards for how ships treat their ballast water.  All ballast water treatment systems must have an approved treatment system on board that meets U.S. Coast Guard approval.

Industrial Processes Benefit from UV Air Purification


Many industrial processes such as manufacturing plastics, rubber or any industrial process which releases toxic or chemical byproducts requires an air purification system.  Companies are required to provide clean air for employees to breathe and are regulated on how much pollutants and contaminants they are allowed to disburse into the air. UV air purification provides a solution to the industrial businesses, with many benefits in addition to clean air.

Ultraviolet (UV) radiation has been used for sterilization of water, surfaces and air for many years, and is becoming more popular in residential settings as well.  UV light is proven to be safe and effective at removing harmful contaminants including volatile organic compounds (VOCs) from the air to improve air quality for overall health and well-being.

UV Air Sterilization is Effective and Cost Efficient

UV air sterilization is proven highly effective is very cost efficient with little to no maintenance required.  UVC germicidal lamps instantly eliminate viruses and bacteria from the air within seconds of exposure.  UV light is measured in wavelengths, referred to as nanometers (nm), with UVC band of 254nm the most effective to eliminate harmful microorganisms.  UV radiation emitted at 185nm is necessary to produce ozone which is used in ozone air purification systems to also remove all odor from the air.

Use of UVC germicidal lamps in air purification systems is a safe and effective method of cleaning the air without the use of chemical byproducts.  With no need to purchase, store or dispose of chemicals, UV radiation requires less maintenance, is much safer to use and is better for the environment.
