The Terrence J. O’Brien Water Reclamation Plant (WRP) in Skokie, Illinois was upgraded with an UV treatment process. The system substantially improved the quality of water throughout the Chicago Area Waterway System, while protecting the region’s drinking water supply in Lake Michigan.




The patented Nedap technology is used to power the 900 state of the art low pressure high output UV lamps, in the most efficient way.



  • Lowest number of UV lampsrequired•Energy saving
  • Ease of operation andmaintenance
  • Extended lamp life, reduction of waste
Saving energy

In the end, the decisive factor was our approach to energy consumption, especially our low-energy solution. This not only saves a great deal of money, but no less importantly, also reduces CO2 emissions, emphasizing Nedap’s focus on focus on more sustainable operation.

Most efficient UV driver technology

After investigating various approaches and technologies, officials determined that UV was the optimal solution for the plant and application. A low total cost of ownership and the fact that, with UV, there are no by-products to worry about were key factors in the decision. Nedap’s Low Pressure Lamp Drivers have a proven efficiency of at least 95%.

Full control with Nedap software

Dedicated Nedap software can be used by engineers to test the electronic platform and to fine tune the UV lamp settings in relation to the required UV levels. The embedded software has a diagnose functionality to report about lamp status, lamp failure, lamp driver temperature and other system operations. A perfect solution to improve the implementation processes and to reduce installation costs and time.
