GlaxoSmithKline upgrades UV disinfection
GlaxoSmithKline has opted to upgrade the existing Hanovia ultraviolet (UV) water disinfection units at one of its UK installations with new state-of-the-art Hanovia Photon medium pressure UV systems
Process water treated by UV disinfection
British company Hanovia will supply Sasol Technology Ltd with four medium pressure UV disinfection systems for its South African production plant, to enable secondary effluent re-use
Microprocessor-driven 'Photon' control modules allow remote operation of the UV units and also ensure full traceability through their data-logging facility.
The UV systems were installed by the Hanovia Spanish agent, TFB-Flygt S.A.
UV disinfection technology was considered to be far more economically viable than traditional pasteurisation and was selected by Cobega SA after the company contacted other Hanovia reference sites across Europe and North Africa.
Hanovia was able to demonstrate significant life cycle cost savings for the medium pressure equipment compared with low pressure UV systems.
"We are very happy with the performance of the UV system," commented the manager of the Cobega plant in St Quirze del Valles.
"It has been operating exactly as expected since it was installed".
Medium pressure UV is highly effective at destroying virtually all micro-organisms, including bacteria, yeasts and moulds - recent independent tests have also shown it to kill Cryptosporidium, an organism resistant to chlorine disinfection.
It does not affect the pH or chemical composition of the product, ensuring the flavour is not affected.
Each UV system consists of a stainless steel treatment chamber containing one or more UV-emitting arc tubes.
Syrup passes through the chamber and the UV kills any micro-organisms present by disrupting their DNA.
Easy to install and with a small footprint, Hanovia UV systems can usually be connected to existing pipework with minimal disruption.
