UV Systems Specially Optimised for Food and Beverage Applications

Hanovia’s (UK) PureLine Ultraviolet Energy Optimised (UVEO) medium pressure UV system uses up to 60% less power than conventional UV systems with just a single UV lamp. This delivers a guaranteed, consistent UV dose with reduced life cycle costs for the food, beverage and brewing industries.

Building on Hanovia’s 90 years’ experience in UV treatment, the PureLine UVEO takes advantage of an optimised hydraulic design to provide up to 60% improvement in the treatment capacity over conventional medium pressure UV systems. This means reduced running costs without compromising on bio-security.

A prime benefit is that treatment is performed with just 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 utilises 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.

PureLine UVEO systems come in three ranges:

The ‘H’ Edition is designed specifically to meet the highly 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, which 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 such as Reverse Osmosis (RO) from premature aging and biofouling.

Medium pressure UV lamps 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 unique ‘eyelid shutter’ design, which protects the operator from exposure to UV light.

The UV system is available in a range of sizes and treatment capacities to meet typical process requirements. It is designed for easy installation into existing pipework and can be fitted with an internal auto-wiper which maintains UV output efficiency by regularly cleaning the quartz sleeve housing the UV lamp. Lamp replacement is also quick and easy, with the system designed to allow easy access, even in small plant rooms.
