Delfland Waterboard in the Netherlands has recently installed a Berson InLine 400+ medium pressure UV system at its Nieuw Waterweg WWTP in Hoek van Holland. The Berson system is used to disinfect effluent, which is then re-used as process water for cleaning and dilution. According to AWZI, the InLine 400+ system was selected as it is more effective than chlorine against water-borne microorganisms such as E coli, it removes the need to handle and store dangerous chemicals, and is reliable, safe, easy to use and maintain.

Another major advantage of the Berson unit is that it uses a stepless power supply, which means significantly lower energy costs and longer lamp life than alternative methods.

All Berson InLine+ systems are compact and can be fitted into existing pipework with minimal disruption.

They also have automated wiping systems, which keep the quartz sleeves surrounding the UV lamps clean.

This means no chemicals are needed for cleaning, and wiping takes place automatically during normal operation, without requiring a by-pass unit.

Based in the Netherlands, Berson UV is a world leader in UV technology for a wide range of applications, including drinking, process and waste-water treatment, dechlorination, ozone removal and TOC reduction.

The company has over 30 years of experience in the design, development, manufacture and distribution of UV systems worldwide.
