Unilever Installs Aquionics UV Disinfection System to Treat Process Water for Margarine Manufacture


Aquionics has recently provided Unilever Netherlands with UV disinfection system to treat process water at its margarine manufacturing plant in Rotterdam. The UV system, installed by Aquionics' Dutch sister company, 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 well-known European 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 Aquionics UV system ensures the count is less than this by destroying virtually any microorganisms remaining in the water," he added.

Municipal 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.

Aquionics (www.aquionics.com), a Halma Company, is a market leader in the manufacture, application and development of UV technology for progressive, non-chemical disinfection and microbiological control. The company's systems are used in a wide variety of applications including food, beverage, pharmaceutical and semiconductor manufacturing.
