TrojanUV3000PTP - Robust, Dependable UV Disinfection for Small Wastewater Applications

A cost-effective, off-the-shelf solution for UV disinfection at small wastewater plants. It's simple to install and operate, and provides a hassle-free, dependable UV solution.

Robust, Dependable UV Solution

Our smallest wastewater system in terms of flow-handling, the TrojanUV3000™PTP (Packaged Treatment Plant), is ideally suited to treat flows up to 2.8 MGD (442 m3/hr).

The TrojanUV3000PTP 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.

Easily Retrofitted

It can be easily retrofitted into existing chlorine contact tanks and effluent channels, and comes pre-tested, pre-assembled and pre-wired to minimize installation costs.

Proven, Chemical-Free Disinfection from the Industry Leader

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. This flexible system has demonstrated effective and reliable performance around the world.

Advanced, Self-Contained UV Modules 
Space-saving, electronic lamp drivers 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 lamp drivers 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.

  • Secondary & Tertiary Effluent UV Disinfection

    The vast majority of wastewater treatment plants around the world provide secondary treatment through conventional activated sludge processes. Some plants have tertiary treatment processes that use an additional filtration process to further improve water quality. The resulting effluent typically requires a disinfection step before discharge back to the environment.


  • Chlorine Conversion to UV Disinfection

    Chlorine gas has traditionally been used for wastewater disinfection for many years. Sodium hypochlorite (liquid bleach) is an alternative to chlorine gas; however, it is more costly and has the same environmental concerns. UV disinfection can easily be retrofitted into an existing chlorine contact tank and has significant benefits compared to chlorine disinfection.
