TrojanUV3000PTP
Designed as a generic type of UV disinfection unit, the Trojan Package Treatment Plant (PTP) is very price competitive and offers an "off-the-shelf" solution for operators with limited budgets and limited treatment requirements.
Our smallest wastewater system in terms of flow-handling, the TrojanUV3000™PTP is ideally suited to treat flows up to 2.8 MGD (441.6 m3/hr). The TrojanUV3000™PTP can be equipped with pre-fabricated stainless steel channels and transition boxes for in-line integration with existing flanged piping – thus minimizing engineering and installation costs.
It can be easily retrofitted into existing chlorine contact tanks and effluent channels, and come pre-tested, pre-assembled and pre-wired to minimize installation costs. Using Trojan’s most proven, modular design and robust components, including low-pressure lamps, these systems are straightforward to operate and require minimal operator involvement.

Advanced, Self-Contained UV Modules
Space-saving, electronic ballasts are housed right in the modules, not in separate external cabinets. This minimizes the footprint of the UV system and eliminates the need for air-conditioning. In fact, the ballasts are cooled by convection, thereby reducing O&M costs. Each UV module features a UV lamp status indicator for at-a-glance confirmation that all lamps are operating.
Proven Performance, Components and Design
The TrojanUV3000™PTP has been validated through regulatory-endorsed bioassay testing and installed in over 1000 installations worldwide. Performance data is generated from actual field testing (bioassay validation) over a range of flow rates, effluent qualities and UVTs - providing confidence in the system design. This modular system is scalable and can be installed outdoors to reduce installation costs.
Highly Flexible Installation Configurations
The TrojanUV3000™PTP have pre-engineered stainless steel channels with built-in weirs that are installed as a freestanding structure. The stainless steel channels are easily integrated with existing flanged piping using Trojan’s highly flexible transition boxes.

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.
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.
