Ultraviolet (UV) light for the Brewery Industry
Process water in contact with beer carries specific microbiological hazards, so it is critical to have the right water treatment strategy in place. Each production process includes specific microbiological hazards. In other words, each process should be protected against specific micro-organisms.
Traditionally, UV systems for the brewing industry are based on ‘general UV dose’ of 25 or 40 mJ/cm2. The experts at bestUV have a different approach. bestUV designs UV systems for the brewing industry that are based on the hazards specific to a stage of beer production.
In breweries, some micro-organisms can be killed with low UV doses. Others require high UV doses. So, the UV disinfection strategy is determined by the type of micro-organism (bacteria, moulds, yeasts), position of the UV treatment to the end-product (beer), and the function of the process water to treat.
The advantage of UV treatment is that is a chemical-free method, which does not change the taste, color, pH, minerals of the process water. No residuals are left in the treated water to get in contact with the end product.

BetaLine UV
BetaLine UV is a series of optimized “L-shaped” units. The BetaLineUV inlet and outlet are positioned at 90°, which gives predictable BetaLine UV system from BestUV South Africahydraulics whilst passing theUV lamps.
The ‘L-shape’ ensures the the BetaLineUV system installation is kept simple (in existing or new pipelines). The UV chamber, which can be installed in a main or bypass pipeline, vertically or horizontally, has the ability to turn 360° around the inlet axis.
The BetaLineUV series uses low-pressure UV lamps wich are also known as ‘amalgam’ and they are available in different lengths, emitting a narrow band of wavelengths. The 254 nm wavelength is most critical for disinfection.
Smart design positions the maintenance end flange on top of the UV chamber, so BetaLineUV maintenance is quite simple and one only needs basic skills. Your maintenance team can easily reach components for removal or replacement.
All BetaLineUV systems prevent fouling of quartz sleeves and UV sensor by an effective manual or electrical operating ‘anti-fouling mechanism’. Even the smallest BetaLineUV unit can be equipped with an electrical anti-fouling mechanism, which is unique in the market.
Depending on the type of BetaLineUV system and the application, it can be installed with a simple or high-tech PLC controller. The user-friendly Lambda controllers ensure the BetaLineUV system operates correctly and efficiently.
BetaLine-E UV
These lamps emit germicidal wavelengths at 254nm. This compact Ecolight lamp is ‘state-of-the-art’ low-pressure lamps, which is especially produced by bestUV for its use in the BetaLine-Eco UV system. Durable lamplife means that the operational costs are fairly low in comparison to the traditional UV lamp.
Considering the latter, bestUV’s integral development of the BetaLine-Eco and the ECOlight lamp the BetaLine-Eco are thus the most compact L-shaped system available on the market today.
The compact ‘L-shape’ construction eases installation in existing or new pipelines, which can be fitted vertically or horizontally.
The BetaLine-Eco UV system is biodosimetric tested and was approved for drinking water by the Austrian Institute Ö-norm (M5873-1:2001) and Norwegian Institute for Public Health (NIPH Liste B) in 2011.
The official approvals permits the BetaLine-Eco to be used in larger waterworks and smaller drinking water facilities to protect consumers against waterborne pathogens, including most bacteria (E.coli, Legionella, Vibrio, Pseudomonas, Klebsiella), viruses (Poliovirus, Rotavirus), parasites (Cryptosporidium, Giardia) and bacterial spores (Bacillus, Clostridium).
The BetaLine-Eco is officially tested and approved by the institutes with a cleaning device. The result is no fouling of the protecting quartz sleeves, which greatly reduces any UV light loss. The CFD (Computational Fluid Dynamics) designed and biodosimetric approved BetaLine-E provides optimal protection against pathogens, delivering the highest performance for lowest operational costs.
AlfaLine UV
AlfaLine UV, the most compact UV system, is designed for all types of water treatment.
The so-called “I-shape”, where the water’s inlet and outlet are in one line, results in low headloss, and very easy installation in new or existing pipelines.
The long-life medium-pressure UV lamps are compact and emit a broad spectrum of wavelengths with a high intensity.
AlfaLine UV systems prevent fouling of the quartz sleeves and UV sensor with an effective manual or electrical ‘anti-fouling mechanism’.
The Power Control System (PCS) enables the UV lamps to run at the most optimal setting to save energy and increase lamplife. This reduces operational costs and increases your return on investment.
The Lambda PLC controller ensures optimal operation of the AlfaLine UV. It provides the operator with valuable information about inputs and outputs, actual UV dose, UV intensity, lamp and system running hours, 4-20mA UV output, maintenance, warnings and alarms. The controller can be equipped with a BUS-connection to communicate with an external master PLC.
KappaLine UV
The KappaLine UV series is the most forward-looking UV system available in the market today.
It features ‘in-one-line’ positioning for the in and out connections and perpendicularly positioned, very compact low-pressure UV amalgam lamps, called EcoLight.
The high-efficient ‘state-of-the-art’ EcoLight lamps emit germicidal wavelengths at 254nm and were specially developed by bestUV for use in the compact KappaLine UV systems.
This unique combination of compactness and high efficiency makes it stand out as the only system available in the market that combines all the advantages of both medium- and low- pressure systems.
The lamplife is extremely long, meaning the operational costs are relatively low compared to others.
The KappaLine UV system is biodosimetric tested and was approved by the Austrian Institute Ö-norm (M5873-1:2001) and Norwegian Institute for Public Health (NIPH Liste B).
These official approvals allow the KappaLine UV to be used in larger waterworks and smaller drinking water facilities to protect consumers against waterborne pathogens, including most bacteria, viruses, parasites, protozoa (Cryptosporidium, Giardia) and bacterial spores.
The KappaLine UV is officially tested and approved with a cleaning device (manual or motor-driven). This device prevents fouling of the protecting quartz sleeves, greatly reducing UV light loss.
The CFD (Computational Fluid Dynamics) designed and biodosimetric approved KappaLine UV provides optimal protection against pathogens, delivering the highest performance for the lowest operational costs.
