Water Purification with UV Light

Safe drinking water one of our most important basic needs and water purification with UV light is an efficient solution. The World Health Organization reports that 1 in 10 people (785 million) still lack basic services, including the 144 million who drink untreated surface water. Fortunately germicidal UVC technology offers one of the safest and most cost-effective solutions for purifying water and eliminating pathogens.

Safety of Water Purification with UV Light

Germicidal UV water disinfection also provides a solution to protecting our precious eco-systems, as unlike traditional methods, UV light methods do not require chemical treatments that generate harmful byproducts. Along with offering safe drinking water, UV light systems have the potential to help reduce pollutants in our oceans, rivers, lakes and other bodies of water across the globe. They are already effectively being used by many municipalities in the U.S. (currently over twenty percent of our wastewater facilities and thousands of municipalities already use UV water purification) as well as throughout the world.

Water Disinfection Advantages

Research points to the fact that there are many advantages to germicidal UV technology. In addition to being environmentally friendly, studies show UV light can effectively eliminate parasites such as cryptosporidium and giardia bacterium. Furthermore, another important characteristic is that the biological contaminates are not able to build up a resistance to UV light. Also chemical-free UV technology only requires a short radiation time and is more cost effective than ozone disinfection units and membrane filters.

Other advantages to UV water purification systems include ease of use, low operating costs, and minimal maintenance. Consumers of the water benefit by the fact that the process does not alter the odor, taste or PH value of the water.

In addition to more municipalities electing to install UV water purification systems, it is also becoming popular as a way to safely treat water in aqua cultures and aquariums. Germicidal UV technology is an efficient method for maintaining water quality without the use of hazardous chemicals and is being used to protect marine life and increase production in fish hatcheries and rearing farms.

Water Treatment Applications

In fact many industries are realizing the benefits and safety of UV water purification. To maintain pools and spas, ozone producing germicidal UV lamps offer an efficient solution as they purify water 3,000 times faster than chlorine. In addition wastewater treatment and water reclamation industries as well as laboratories, hospitals, clinics, nursing homes, universities, schools, and veterinary clinics are all successfully using UV water disinfection systems. UV germicidal lamps also effectively treat large capacity vessels in ballast water treatment systems.

UV Ink Curing Lamps

The process of UV ink curing has been around since the 1960’s and uses high intensity ultraviolet light to create a photochemical reaction. By using the proper intensity of UV wavelengths, a byproduct is produced that hardens resin and dries inks. It offers numerous advantages over traditional heat-cured systems and has become the method of choice for many as it safely and cost-efficiently cures inks, as well as adhesives, coatings, varnishes, decorative glazes and lacquers.

UV Curing Benefits

UV ink curing systems are easy to operate and maintain and more environmentally-friendly than traditional systems. Since UV ink curing does not produce noxious fumes as heat-cured inks, it does not require expensive exhaust systems to counteract the fumes. UV systems are used by industries such as automotive, electrical, industrial, and medical.

Another benefit of curing inks with UV light is that the ink dries instantaneously, which greatly speeds up production times as well as helps to improve the overall quality of the product. The speedy drying time means products are ready for shipment much quicker and the chance of dust or other airborne objects ruining the finished product is reduced.

UV Ink Curing Lamps

The types of UV lamps used for UV ink curing includes low pressure and medium pressure UV (MPUV) curing lamps as well as amalgam UV curing lamps. Using a wavelength of 254nm, UV low pressure lamps are used to cure inks in high-quality magazines and newspapers. In addition since low pressure lamps operate on much less power than MPUV lamps, they are ideal for applications requiring dimming.

MPUV lamps are the best choice for applications that require a higher intensity of UV light due to shorter exposure times and need high-speed press runs. Also there are some industries that prefer amalgam lamps for the efficient drying of inks and adhesives with a cationic base. Amalgam lamps produce outputs of 300 to 1000 watts, of which one-third is usable UVC energy, and offer the opportunity to downsize a system while still maintaining maximum efficiency for UV curing.

With the combined resources of LightSources in the U.S. and LightTech in Europe, we are global leaders in UV curing lamps as well as UV air treatment systems. We partner with OEMs of any size to design, engineer and mass-produce new types of proprietary and specialty lamps cost-effectively and with short turnaround.
