Xylem's Wedeco TAK 55 Smart UV system makes the disinfection of low wastewater flows as easy and cost-effective as possible, without any compromise in quality or flexibility. The TAK 55 Smart is the perfect fit for small to medium effluents of varying wastewater qualities, from sewer overflows to tertiary wastewater reclamation.

The TAK 55 Smart lamp modules are engineered for long-term use, while the compact UV lamp arrangement allows for highly concentrated power in a small space. The result is guaranteed disinfection performance even with larger volume flows and low UV transmittance (UVT) from the wastewater. 

For improved economics and maximum sustainability, TAK 55 Smart units employ low-pressure, high-output, amalgam Ecoray UV lamps and ballasts. The low lamp count, coupled with the long service life of Ecoray lamps, result in exceptionally low maintenance costs. Used in combination with the variable power option, the Ecoray technology results in excellent energy efficiency under all operating conditions. Particularly in dimmed mode, they realize average energy savings of up to 20% compared to existing technologies. Additionally the sensor-controlled OptiDose monitors operating conditions in real time, including flow, UV transmittance, and UV intensity. Then, with proven control logic, OptiDose adjusts the energy consumption to the minimum needed to meet dosing requirements. No assumptions are made regarding process parameters, ensuring cost savings and disinfection confidence at all times.

The Wedeco TAK 55 Smart UV system also maximizes operator usability with minimum maintenance. The EcoTouch controller unifies all sensor signals, alarms, SCADA connectivity, and OptiDose closed loop control for easiest monitoring and control.



Ready to assemble, including the disinfection channel, the TAK 55 Smart is available in ten sizes to match specific site requirements. It can also be easily customized with different types of channel material (i.e. concrete, stainless steel, HDPE), single or double UV bank arrangement, an optional automatic wiping system, various cabinet designs, as well as sophisticated UV monitoring and control features. 

Electric components like ballast cards are separated from UV lamp modules for easy maintenance and operational stability. Cabinets are rated for both indoor and outdoor service, even at high ambient temperatures, with an optional stainless steel enclosure and air conditioning, providing flexibility in plant construction or retrofitting.

Cleaning is simple and safe thanks to the TAK 55 Smart’s optional automatic, chemical-free wiper system. The excellent cleaning performance of the wiping system has been confirmed by independent institutions and significantly reduces the formation of deposits.

To meet the highest UV disinfection standards, the system has been extensively tested in line with the latest IUVA protocol for the disinfection of secondary treated effluents. It even meets the most stringent validation requirements as outlined in the USEPA’s UVDGM (2006). With its validated dose design, Xylem can fine tune the design to match water quality, operating conditions and discharge requirements. This approach ensures that the system design is not over sized or under sized. Optimizing for specific site requirements results in the smallest possible UV system without compromising performance, ultimately saving upfront capital costs and operational costs for the life of the system.

About Wedeco

Wedeco was founded in 1975 in Herford, Germany to develop chemical-free and environmentally friendly water treatment technologies, including ultraviolet light and ozone systems. There are more than 250,000 installed Wedeco systems for UV disinfection and ozone oxidation globally in private, public utility and industrial locations. Wedeco introduced ozone technology in 1988 and has been expanding internationally ever since. UV disinfection systems have a number of applications including water treatment and aquaculture. Ozone disinfection systems have applications in drinking water, wastewater, process water, product polishing, bleaching, ozonolysis / synthesis and deodorization.
