TrojanUVSwiftSC
Designed to meet the needs of large and small communities, the TrojanUVSwift™SC incorporates energy-efficient, low-pressure lamps.
With units designed to treat flow rates of 15 GPM to 15.4 MGD (0.6 to 2430 m3/hr), these compact, robust UV systems offer communities an efficient, economical solution for drinking water disinfection.
Like all Trojan drinking water products, the TrojanUVSwift™SC is bioassay validated, having undergone rigorous DVGW and USEPA certification to ensure verified dose delivery, maximum public safety and peace of mind. It’s engineered and built to provide reliable performance, simplified maintenance, and reduced operating costs with innovative features like a hydraulically optimized, “L-shaped” reactor, high-intensity amalgam lamps and optional automatic or manual sleeve wiping.

Compact Reactor for Installation Flexibility
The efficient reactor can be installed vertically or horizontally, increasing installation options. The lamps and sleeves are fully serviceable from one side – allowing the system to be installed tight to walls, other equipment or piping. The “L-shaped” reactor design is also 40% more efficient than “U-shaped” systems.
Bioassay Validated Performance
All TrojanUVSwift™SC units are certified for source water of various qualities, having been DVGW bioassay tested under a range of UV transmittances (UVT) and flow rates. Bioassay performance data for the TrojanUVSwift™SC line was generated under the worst-case orientation – with a 90° elbow at the inlet.
Energy Efficient, High-Output Amalgam Lamps
The TrojanUVSwift™SC requires 1/2 to 1/3 fewer lamps to deliver the required dose compared to traditional UV systems using low-pressure lamps. With fewer lamps, the TrojanUVSwift™SC is compact and draw less energy than competitive high-output systems – minimizing capital and operating costs.
Robust Sleeve Wiping Systems
The automatic wiping systems minimize fouling of the quartz sleeves. The system operates online while the lamps are disinfecting, reducing downtime.

What is ultraviolet (UV) light?
Ultraviolet (UV) light is a form of light that is invisible to the human eye. It occupies the portion of the electromagnetic spectrum between X-rays and visible light. The sun emits ultraviolet light; however, much of it is absorbed by the earth’s ozone layer.A unique characteristic of UV light is that a specific range of its wavelengths, those between 200 and 300 nanometers (billionths of a meter), are categorized as germicidal – meaning they are capable of inactivating microorganisms, such as bacteria, viruses and protozoa. This capability has allowed widespread adoption of UV light as an environmentally friendly, chemical-free, and highly effective way to disinfect and safeguard water against harmful microorganisms.How does UV work?
Unlike chemical approaches to water disinfection, UV light provides rapid, effective inactivation of microorganisms through a physical process. When bacteria, viruses and protozoa are exposed to the germicidal wavelengths of UV light, they are rendered incapable of reproducing and infecting.Microorganisms are inactivated by UV light as a result of damage to nucleic acids. The high energy associated with short wavelength UV energy, primarily at 254 nm, is absorbed by cellular RNA and DNA. This absorption of UV energy forms new bonds between adjacent nucleotides, creating double bonds or dimers. Dimerization of adjacent molecules, particularly thymine, is the most common photochemical damage. Formation of numerous thymine dimers in the DNA of bacteria and viruses prevents replication and inability to infect.What are the benefits of using UV?
For many decades, chlorine was successfully used in drinking water treatment. However, there are chlorine-resistant organisms, such as Cryptosporidium and Giardia, that are harmful to humans. For example, in 1993, over 400 people died and over 400,000 became ill as a result of a Cryptosporidium outbreak in the drinking water supply of Milwaukee, Wisconsin, USA.UV is highly effective at treating these chlorine-resistant organisms and produces no disinfection by-products. Many large cities have installed UV as part of a multi-barrier strategy to ensure their drinking water is safe. For example, New York City is currently building the world's largest UV disinfection facility using TrojanUV reactors. Once completed, the UV facility will be able to treat a total of over 2.2 billion gallons a day.
Cryptosporidium Barrier
Cryptosporidium is a harmful protozoa that can cause severe illness and even death in some individuals. Fortunately, these chlorine-resistant protozoans can easily be inactivated with a low UV dose.Primary Disinfection
By employing UV as the primary disinfectant, the required chemical CT can be reduced or eliminated (dependant upon local regulations).Multi-Barrier Strategy
UV is a perfect fit as an additional barrier in a multi-barrier strategy to provide additional public safety.Giardia Barrier
Giardia can be found worldwide and is one of the most common waterborne parasites. Low UV doses can inactivate Giardia without forming disinfection by-products.
