Germicidal UVC water purification offers a safe, effective and cost-efficient alternative to chemical treatment. With no harmful byproducts, its worldwide use is critical for eco-systems and reducing pollutants in rivers, oceans and other bodies of water.

The use of germicidal UVC continues to grow in the industries of water reclamation, waste water, drinking water, industrial and commercial process water, pool and spa, aquaculture and life sciences.

In aqua culture, germicidal UVC technology is a safe and economical method for maintaining a healthy operating environment free of pathogenic micro-organisms that can adversely affect the controlled ecosystem. This method of water treatment can be used for both freshwater and saltwater applications and serves to prevent disease and increase production.

Both aquaculture and aquariums offer a significant opportunity for growth in the germicidal UVC market. Without the use of chemicals or the production of harmful byproducts, our germicidal lamps safely and efficiently disinfect water by killing lethal organisms, such as the myxozoan parasite, with UVC radiation at a wavelength of 254nm. UVC is absorbed by the pathogen’s DNA, making it ineffective at reproducing, without any harm to marine life or vegetation. This wavelength can also remove chlorine and destroy ozone with the added benefit of controlling algae growth.

Light Sources and LightTech’s high output quartz germicidal lamps and low pressure amalgam lamps are used in aqua culture farms and aquariums worldwide.

Germicidal UVC technology is a safe and economical method for drinking water purification; in some cases, UVC treatment is more effective than chemical disinfectants because it can kill pathogens, such as cryptosporidium and giardia bacterium, that chlorine cannot. Additionally, UVC leaves no byproducts and does not change the color, taste, odor or pH of the water.

In the United States, almost every source of drinking water – including rivers, recycled water reservoirs, aquifers, and lakes – have some level of contamination due to toxic bacteria, chemicals and heavy metals. In accordance with new government legislation, municipalities are looking for new ways to treat water. UV technology is more cost effective than ozone disinfection units and membrane filters.

Light Sources and LightTech’s strategic partnership offers low pressure standard quartz germicidal lamps and low pressure high output germicidal lamps are used in municipal and domestic applications worldwide to disinfect, sanitize and oxidize drinking water, as well as to reduce TOCs and chloride/chloramines. Our germicidal lamps can generate UV radiation at 185nm and 254 nm – the combination of which is necessary for the photooxidation of organic compounds. Radiation at 185nm produces ozone, which is active oxygen. Ozone is one of the most effective natural bactericides and can kill almost every form of virus. Radiation at 254nm is an effective sanitizer. At this wavelength, UVC is absorbed by the organism’s DNA, eliminating its ability to reproduce.

The life sciences industry, which includes pharmaceuticals, biotechnology, and medical device markets, requires a high level of water disinfection. Germicidal UVC technology is an efficient and cost-effective method that not only disinfects water, but also reduces TOCs and destroys ozone and chlorine/chloramines. This technology can be used in both pre-treatment and process streams.

Light Sources and LightTech’s standard (425mA) and high output (800mA) lamps are used in life science germicidal applications throughout the world. Our strategic partnership offers products of the highest-level of performance in purifying water to the exacting standards required for the life sciences industry. Germicidal UVC lamps add no odor, taste or harmful byproducts.  At the wavelength of 254nm, germicidal lamps use only UVC to destroy micro-organisms and remove chemical compounds in the water, making it a safe and environmentally-sound technology.

Germicidal UVC technology is a safe and effective alternative to chlorine-based disinfectants, which have harmful and irritating side effects.

Chlorine reacts with ammonia- and nitrogen-based compounds, creating chloramines which are responsible for the strong odor. Chloramines cause skin and eye irritations and create a chemical off-gas that is unhealthy to breathe. This off-gas also can potentially corrode pool structures

Light Sources and LightTech’s strategic partnership offers medium pressure high power lamps disinfect pool water and reduce chemical compounds, such as chloramines. Our germicidal lamps can generate UV radiation at 185nm and 254 nm. At the 254nm wavelength, UVC is absorbed by the organism’s DNA, eliminating its ability to reproduce. Radiation at 185nm produces ozone, which is active oxygen. Ozone is one of the most effective natural bactericides and can kill almost every form of virus. Radiation at 254nm is an effective sanitizer, even oxidizing body oil, urine, perspiration, fecal matter, and cosmetics. It can prevent and destroy chloramines by breaking down the N-CL bonds and by forming oxidizing hydroxyl radicals.

Other benefits of ozone include the elimination of foam and scum lines and rapid disinfection – working 3,000 times faster than chlorine. It is gentle to spas, pools, and equipment and will not affect pH levels or add any perceptible odors or colors. Ozone combines small, insoluble particles, making larger particles that can be trapped by filters.

Waste water is any water that has been adversely affected in quality by human influence and contains a wide range of potential contaminants. It includes liquid waste discharged from domestic, commercial, industrial and agricultural use.

Germicidal UVC technology is a safe and economical method for the purification of drinking water; in some cases, UVC treatment is more effective than chemical disinfectants because it can kill pathogens, such as cryptosporidium and giardia bacterium, that chlorine cannot. And it has the added benefit of reduced maintenance costs.

In the United States, over twenty percent of wastewater facilities and thousands of municipalities already use UV water purification in place of chemical disinfectants to meet strict federal and local standards for public safety and environmental protection.

Germicidal UV lamps disinfects instantaneously by exposing pathogens to UVC light at a wavelength of 254 nm. This wavelength penetrates the DNA membrane of the organism, making it incapable of reproducing. Light Sources and LightTech’s strategic partnership offers low pressure UVC lamps, low pressure amalgam lamps and medium pressure high power lamps are used in waste water treatment plants worldwide.

Our germicidal lamps are used in the water reclamation process to assure that water leaving the facility meets strict regulations. Once purified, the water can be safely recycled for different applications. Most reclaimed water is used for non-potable purposes, such as toilet water, cooling water for power plants, concrete mixing, artificial lake supply, and irrigation.

Recycled from domestic wastewater, rainwater, and industrial process water, reclaimed water is a critical component in sensible water management. Water reclamation contributes to the health of the environment by helping to keep pollution out of sensitive eco-systems and by decreasing the amount of contaminants that flow into natural bodies of water.

Light Sources and LightTech’s strategic partnership offers medium pressure standard lamps and medium pressure high power lamps are used in municipal and domestic applications worldwide to disinfect, sanitize and oxidize reclaimed water, as well as to reduce TOCs and chloride/chloramines. Our germicidal lamps can generate UV radiation at 185nm and 254 nm – the combination of which is necessary for the photo oxidation of organic compounds. Radiation at 185nm produces ozone, which is active oxygen. Ozone is one of the most effective natural bactericides and can kill almost every form of virus. Radiation at 254nm is an effective sanitizer. At this wavelength, UVC is absorbed by the organism’s DNA, eliminating its ability to reproduce.
