Nedap supplied the lamp drivers for the UV wastewater purification plant in Chicago. As one of the largest UV waste water installations in the world, the plant can treat 1,700 million liters of wastewater.
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.
Low number of UV lampsrequired
Ease of operation andmaintenance
Extended lamp life, reduction of waste
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.
UV disinfection and industrial curing are highly sustainable processes that reduce the use of chemicals. UVC has been used as far back as the 1930s, but the technology remains relevant today – and Nedap is increasing innovation in the sector.
New developments in curing and disinfection are accelerating the growth of the UV market. At Nedap, we support UV businesses to develop new applications and further optimize processes for more sustainable disinfection and curing.
Nedap’s next-generation lamp driver platform has updated integrated software. This gives operators more data and control over settings and parameters compared to previous models. However, this can lead to more complexity. To make data relevant for users, it’s essential to provide easy access and deliver relevant insights. In this way, data leads to a more sustainable and cleaner operation.

How more sustainable operations helps create better profits
With rising energy costs, supply chain pressures and increased social interest in sustainable production, it’s more important than ever that the equipment you use high class perform while reducing your carbon footprint. By reducing the carbon footprint, businesses also save energy costs, which helps create better profits.
That’s where our technology comes in. When selecting an UV lamp driver, of course, the initial cost is a crucial consideration. End users must factor in the total cost of ownership – not simply the upfront cost of a lamp driver. The energy and maintenance costs need to be considered – longevity is key here. Using smart UV lamp driver technology helps to create a more sustainable operation, reducing carbon footprint and saving costs at the same time.
Based on benchmark research, UV systems with Nedap UV lamp drivers are up to 5% more energy efficient than other drivers in the market, due to higher Lamp driver efficiency, lower Total Harmonic distortion (THD) and higher Power Factor (PF). With the current energy prices, this results in substantial operational cost savings. Depending on the price of industrial energy, the operating hours per year, and the lamp power used (kW) you can calculate the energy savings for end-users of your application.
- Industrial energy price: $ 0,1075 per kwh and € 0,150 per kwh (August 2022)
- 6000 operating hours
- 5% efficiency increase
- 60 kW total lamp power
When the total lamp power in your application is 10 kW, a 5% efficiency increase results in 3500 kWh savings per year. If your UV application uses a total of 60 kW of lamp power, this results in 21,000 kWh (6x 3500) savings, and €3,160 (6x €526) or $2,262 (6x $377) per year . A reduction of 21,000 kW also equals a reduction of 4200 kg CO2 (source: European Environment Agency).
The initial price of your UV solution may be higher using a premium UV driver, but your customer will experience substantial energy costs savings. The payback period is the time between the initial investment date and break-even point, the moment you save money compared to a competitive product. This depends of course, very much on the UV application.
First, your UV systems offer you more UV, due to better efficiency. Secondly, Nedap’s high-quality UV lamp driver increases the lifespan of UV lamps significantly – an important reason for all major lamp manufacturers to recommend Nedap’s lamp driver technology. Both features lead to a more sustainable operation.

UV applications offer optimal solutions for water treatment, air and surface disinfection, and curing. To operate UV lamps, lamp drivers, also called electronic ballasts are commonly used. Depending on lamp type, the drivers take care of pre-heat, ignition, and warm-up of the UV lamps. Selecting the right UV lamp driver can optimize efficiency, prevent mains power supply problems, and improve ease of installation. Far from simply acting as a lamp driver, it improves the total cost of ownership and sustainability of your application, and, as a result, its viable use cases.
When selecting a high-quality UV lamp driver, there are several aspects which must be considered. In many cases, these aspects may only become apparent after the lamp driver has been in use for some time – the difference between a high-quality UV lamp driver and a poor one is not immediately obvious. We’ve listed some important criteria below:

First, if your UV systems wastes less energy, due to better efficiency, it will have a smaller carbon footprint. Secondly, the Nedap high-quality UV lamp driver increases the lifespan of UV lamps significantly – an important reason for all major lamp manufacturers to recommend Nedaps lamp driver technology. Both features lead to a more sustainable operation.
There are two groups of drivers that are used depending on the specific type of UV project: Low-Pressure UV Lamps and Medium-Pressure UV Lamps.
Low-pressure lamps, limited to 1000W, provide exactly the right wavelength of light to fight bacteria and have several advantages compared with medium-pressure lamps. The conversion rate from electrical to UV energy for low-pressure lamps stands at around 34 to 38 percent. This means they deliver a higher rate of efficiency than medium-pressure UV lamp drivers, where the conversion is around 12 percent.
While the higher efficiency level of low-pressure lamps may be advantageous in certain circumstances, medium-pressure lamps can achieve higher levels of electrical power – as high as 36 kW. As such, medium-pressure lamp drivers are likely to be more suitable for projects that have limited space and need a high UV level, as in some space-restricted water disinfection systems.
Medium-pressure lamp drivers also produce light of multiple wavelengths, which is beneficial for advanced oxidation. Besides attacking the DNA of bacteria, they can also be combined with other solutions to help with the breakdown of chemical substances.
The efficiency of UV lamp drivers is crucial for several reasons. Firstly, poor quality lamp drivers can result in damage to the UV lamp from over-voltage or component stress. Before the advent of electronic lamp drivers, many businesses relied on electromagnetic devices, which were inefficient, offered less control in terms of power, and required extra attention in terms of their mounting and space requirements.
At Nedap, we are proud of the efficiency and power output levels we are able to achieve with our UV lamp drivers. We advise you to select UV sources with higher levels of energy efficiency, lowering costs for your customers business over the lifetime of a product, reducing carbon footprint, and improving your product reliability. Initial low-cost lamp driver systems offering limited features with regard to the power factor, THD, and efficiency will lead to higher operational costs during the lifetime of your UV systems.
Nedap’s driver technology is already employed to improve the safety of drinking water and optimize the printing process for millions of customers around the world.
