We would like to avoid Legionella in our cooling towers – what can AquaWorker do?

With AquaWorker as a UV treatment for your cooling tower water, you get an effective, reliable, and chemical‑free protection against Legionella. UV light inactivates bacteria directly in the water flow and prevents them from multiplying – without affecting water chemistry, materials, or the environment. With UV treatment, you gain a modern, proven, and cost‑effective solution that protects people, facilities, and operations around the clock.

How can you reduce the use of biocides in water systems without risking operational disruptions?

By supplementing or replacing parts of the chemical treatment with AquaWorker , microbiological growth can be continuously controlled without increasing the risk of operational issues. UV treatment acts directly in the water flow, reduces the need for high biocide doses, and provides stable and predictable protection. The result is lower chemical consumption, safer operation, and reduced environmental impact. Reducing the reliance on biocides to control bacterial levels in cooling systems also leads to fewer extraordinary measures, such as shock dosing or using municipal drinking water to maintain cooling capacity.

We want to improve the water quality in our aquaculture system – can AquaWorker help us?

Absolutely. AquaWorker is typically installed in the circulation loop of land-based recirculating aquaculture systems, RAS. Its key benefits include improved water clarity, reduced turbidity and suspended solids, while effectively controlling bacterial load. These advantages are particularly valuable during the fry stage and in start-feeding departments, where water quality is critical for fish health and survival. AquaWorker has been installed in numerous aquaculture plants.

AquaWorker

Industrial UV for process water

AquaWorker is a powerful self-cleaning UV system that reduces biological and organic pollutants in water systems such as cooling and aquaculture systems. AquaWorker prevents the growth and spread of microorganisms which can be hazardous to people's health and cause degradation and efficiency loss in water systems without biocides.

UV for increased availability and decreased risk without biocides

Increases availability of aquaculture- and cooling systems
Reduces the risk of Legionella, Norovirus, and Pseudomonas outbreaks
Minimizes usage of biocides and associated handling- and health risks
Facilitates increased reuse of process water
Reduces the amount of chemicals in waste streams

Flexible and Robust

AquaWorker is designed for intake water applications and recirculation systems and can be adjusted according to the desired degree of purification and flow.

Extremely durable materials and a robust design meet the tough demands of corrosive industrial environments to ensure long-term trouble-free operation. AquaWorker can be installed in fresh- or seawater applications.

Adding to the flexibility, the reactor can be installed vertically or horizontally. The reactor and control panel are installed separately and can be integrated with both new and already existing systems.

Automatic cleaning system

AquaWorker is equipped with a unique and patented cleaning system capable of removing hard-forming scaling as well as fouling. This way the lamp sleeves are kept clean, ensuring optimal performance throughout the product's lifetime.

Optimized design for low operational cost

AquaWorker is designed with a flow-optimized interior that ensures a uniform distribution of the UV dose. The design minimizes the pressure drop, making the product very energy efficient.

AquaWorker’s long-life UV lamps are selected to work efficiently in cold as well as warm conditions. These low-pressure lamps combine high UV power density with excellent efficiency contributing to the low energy consumption of AquaWorker.

Want to run biocide-free in your cooling tower?

Contact us to book a meeting with our Product Manager – via Teams or on-site. We’ll help you find the right solution for biocide-free operation and show you how to reduce chemical use in a safe and efficient way.

UV lamps selected for high performance

AquaWorkers light sources have an operating life of up to 16000 hours if the system is in continuous operation, meaning the light sources only need to be replaced every 18th month.

AquaWorker offers reliable operation and requires minimal maintenance. The product is designed for easy lamp change-outs and cleaning. No tools are required and the lamp connectors are detachable. The touch screen makes all information, such as alarms and power consumption, easily accessible.
