KeyBenefitsTrojanUV4000Plus™

Increased operator, community and environmental safety. Uses

environmentally-friendly ultraviolet light – the safest alternative for wastewater disinfection. No

disinfection by-products are created, and no chlorine compounds must be transported, stored

or handled.

Ideal for challenging wastewater applications. Treats a wide range of

wastewater flows, including effluents with UV transmittance as low as 15%, combined &

sanitary sewer overflows, and water for reuse applications.

Proven, regulatory-endorsed disinfection based on actual dose delivery testing

(bioassay validation), and over 375 installations worldwide. Verified field performance data

eliminates the sizing assumptions of theoretical dose calculations.

Reduced installation costs. Easily retrofitted into existing chlorine contact chambers,

leaving the majority of the chamber available for storage, by-pass or emergency back-up

– eliminating the expense and footprint associated with the construction of new structures.

Operator-friendly maintenance. Features significantly fewer lamps, modules that are

electrically separate, and an integrated power winch to remove modules from the channel to a

convenient working height.

Dual-action sleeve cleaning system improves performance and reduces labor costs. Unsurpassed chemical/mechanical cleaning system maintains maximum

sleeve transmittance, and works online while disinfecting.

Optimized for efficient operation. Uses a fraction of the number of lamps required

by conventional low-pressure systems, and features high efficiency, variable-output electronic

ballasts and dose pacing to minimize power consumption.

Guaranteed performance and comprehensive warranty. Trojan systems

include a Lifetime Disinfection Performance Guarantee. Ask for details.

The TrojanUV4000Plus™ has been optimized for disinfection of low quality wastewater using high intensity lamps, and vortex mixers (left) to increase flow turbulence around the lamps. Trojan’s UV technology allowed the City of Honolulu, Hawaii to disinfect primary effluent at their Sand Island treatment facility (right), and thereby save hundreds of millions of dollars that would have been required to build secondary treatment facilities.

The intensity and breadth of UV wavelengths delivered by medium-pressure lamps are significantly greater than low-pressure lamps. A larger portion of the ultraviolet light that medium-pressure lamps emit is absorbed by the DNA of microorganisms, which results in effective disinfection with fewer lamps.

Comparison of Low-Pressure and Medium-Pressure Lamp Technologies

Trojan pioneered the use of high intensity, medium-pressure ultraviolet lamps for wastewater disinfection. The technology minimizes the system footprint, and offers the capability of treating high flow rates, and low quality effluents with UVT levels as low as 15%.

The dose pacing system of the TrojanUV4000Plus™ uses a PLC-based controller that monitors lamp age and water quality (e.g. flow rate, UVT, turbidity) and adjusts lamp output to ensure full disinfection is achieved using minimal power.

In this retrofit installation, each reactor was installed in one pass of the existing chlorine contact basin with only minor modifications to the channels. This allows the majority of the basin to be used for storage, by-pass or emergency back-up.

The eight TrojanUV4000Plus™ reactors used to disinfect 94,632 m3/h at this large wastewater treatment facility require a footprint measuring only 2032 x 3048 mm – a fraction of the space needed for chlorine disinfection.

Operator Comments About the TrojanUV4000Plus™ “It does the job and it’s simple to operate.” “It’s user-friendly and low maintenance.” “We’re getting a better kill than we expected. We’ve always dealt with chlorine and sulphur dioxide, but this does

every bit as well. It doesn’t seem to need as much maintenance – there’s no dangerous chemicals, and it’s cleaner.”
