TrojanUV3000Plus

Designed using the latest UV technology, the TrojanUV3000Plus™ uses energy-efficient amalgam lamps. These high output lamps are automatically dimmed when flow demand drops or when the water quality changes.

This highly flexible system has demonstrated its effective, reliable performance around the world.  It features Trojan’s patented ActiClean™ chemical/mechanical cleaning system to minimize maintenance. It is well suited to wastewater disinfection applications with a wide range of flow rates, as well as challenging effluent (primary and combined sewer overflows) and high level disinfection such as tertiary wastewater reclamation and reuse.

ActiClean™ Eliminates Sleeve Fouling
The dual-action, chemical/mechanical cleaning with the ActiClean™ system provides superior sleeve cleaning and reduces maintenance costs. Fouling and residue build-up on quartz sleeves reduces system efficiency. ActiClean™ maintains at least 95% transmittance, ensuring sleeves are clean and the system is consistently delivering accurate dosing while reducing power consumption. Cleaning occurs automatically while the lamps are disinfecting. There’s no need to shut down the system, remove or bypass lamp modules for routine cleaning.
 
Amalgam Lamps Require Less Energy
Trojan’s amalgam lamps produce significantly higher UV output than conventional low-output lamps, therefore fewer lamps are required to deliver the required dose, which reduces O&M costs. Trojan's high-efficiency lamps are validated to deliver 98% of full UV output after more than one year of use.
 
Advanced, Self-Contained UV Module
The electronic ballasts are housed right in the module, reducing the system footprint, minimizing installation time and costs, and eliminating the need for separate external cabinets since they are cooled by convection. The ballast enclosures are rated TYPE 6P (IP67) – air/water tight. The entire system can be installed outdoors to reduce capital costs - no building, shelter or HVAC is required.
 
Regulatory-Endorsed Bioassay Validation
The TrojanUV3000Plus™ has been thoroughly validated through real-world bioassay testing under a wide range of operating conditions. In-field bioassay testing offers the peace of mind and improved public and environmental safety of verified dose delivery – not theoretical calculations.

  • 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.

  • Why is UV better than chlorine?

    UV offers a key advantage over chlorine-based disinfection, due to its ability to inactivate protozoa that threaten public health – most notably Cryptosporidium and Giardia. UV does not add any chemicals to the water and does not produce disinfection by-products. 
     
    Chlorine gas is a highly toxic chemical that must be transported and handled with extreme caution. It is a strong oxidizing agent that can be extremely dangerous to humans. The increasing concerns about the hazards of chemical disinfection to the public, the operators, and the environment have dramatically increased the cost of chemicals and the administrative efforts required to meet safety regulations. As a result, UV disinfection has increasingly become the choice for wastewater disinfection due to some significant advantages over chemical-based disinfection.

  • Water Reuse

    The advanced treatment and reuse of wastewater is becoming increasingly common as municipalities address high water demands and shrinking supplies. Australia, Spain, Italy, California and Florida, to name a few, must balance increasing population growth, dry climates and heavy irrigation/agricultural demands.

  • Secondary & Tertiary Disinfection

    The vast majority of wastewater treatment plants around the world provide secondary treatment through conventional activated sludge processes. Secondary processes are effective upstream of UV disinfection since they remove particles and improve water clarity.

  • Low Quality Water Disinfection

    UV is proven effective in challenging applications such as combined sewer overflows (CSO), storm and sanitary sewer overflows (SSO), blended effluents as well as disinfection of primary treatment effluent.
