UV disinfection system treats process water

Unilever Netherlands has installed a Berson UV disinfection system to treat process water at its margarine manufacturing plant in Rotterdam.

Unilever Netherlands has installed a Berson UV disinfection system to treat process water at its margarine manufacturing plant in Rotterdam.

The UV system ensures that all mains water used in the plant has a CFU*/ml count of less than 100.

The water is used in the manufacturing of margarine brands such as Becel and Blue Band.

"Although incoming mains water is of very high quality, it cannot always be guaranteed to have less than 100 CFU/ml," commented a Unilever manager.

"The Berson UV system ensures the count is less than this by destroying virtually any microorganisms remaining in the water," he added.

Mains water is first drawn into a break tank before being pumped through the UV system at a flow rate of 40m3/hour.

From there it passes through a mesh filter to remove any large particles.

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.
