Treatment is performed with a single medium pressure UV lamp, eliminating the need to install a bigger system with multiple lamps at higher flows. This saves on up front capital costs and lifetime spares costs. 

The system uses a smart control system that reads the process water conditions using flow, transmittance and chlorine sensors to control the electronic ballast with ‘stepless’ power, which can then automatically adjust the power from 100% to 30%. This feature helps increase the life of the medium pressure lamp and provides further savings on power costs. 

•  The ‘H’ Edition is designed to meet stringent food, beverage and brewing industry regulations. All wetted parts use food grade-approved materials, while a UV chamber with a high specification internal finish is available if required

•  The Standard edition provides required levels of disinfection and prevents downstream contamination before reverse osmosis (RO) filters and at the point of use.

•  The Dechlor edition, based on either H or Standard chamber designs, which provides guaranteed levels of dechlorination coupled with strong disinfection to protect downstream processes from premature aging and biofouling.

Medium pressure UV lamps are said to provide the highest possible UV output at the specific wavelengths required to destroy microorganisms. Medium pressure UV is especially effective against chlorine-resistant pathogens such as Cryptosporidium and Giardia. Reduced reliance on chlorine helps protect downstream contamination of filters early on in the water treatment process. Medium pressure UV is also very effective at removing ozone from process water, ensuring product quality before bottling.

UVEO technology provides the food, beverage and brewing industries with optimised UV systems in line with requirements. The PureLine UVEO’s chamber size, lamp power and control systems have been tested to ensure not only that high levels of process water disinfection are achieved, but also that green initiatives are met by lowering power consumption. 

The PureLine UVEO is provided with Hanovia’s patented ‘UVGuard’, which allows safe checking of the UV sensor (performance monitoring instrument) using a special ‘eyelid shutter’ design, which protects the operator from exposure to UV light.
