Priva Vialux line: Efficient UV-C light water disinfection

Safe reuse of (drain) water with the Priva Vialux line and optimum efficiency in water and fertilizer use for your crop.

Introduction
Clean, pathogen-free water is essential for stable crop performance. When you reuse drain water, you also take on the risks that come with it. The Priva Vialux Line uses UV-C disinfection to inactivate fungi, bacteria and viruses, without adding chemicals.

This allows you to safely reuse water, reduce discharge and keep your irrigation process stable.

UV-C disinfection can be applied for:

  • (Pre-)treatment of incoming water
  • Treatment of drain water
  • Treatment of discharge water 

Why this matters

Water quality plays a crucial role in crop health and development. Whether you use incoming water sources or recirculate water, factors such as pathogens, nutrient levels and contaminants can impact your crop, sometimes without visible signs early on.

Maintaining stable water quality helps reduce discharge, conserve fertilizers and ensures compliance with regulations. Reliable disinfection supports both your incoming water quality and recirculation process, even when conditions change.

Guidelines: Efficient greenhouse water management

Optimize your greenhouse water cycle to reduce losses, improve water quality, and support healthier crops.

Benefits

Why growers choose Priva Vialux-Line

Discover the benefits of Priva Vialux-Line

Reliable water reuse
Safely recirculate irrigation water without compromising quality. Reusing drain water helps reduce discharge and fertilizer loss, while keeping your operation efficient. In most cases, this leads to a payback time within three years.
Reliable treatment of incoming water
Ensure consistent water quality from the start. Treating incoming water sources, such as rainwater or surface water, reduces risks and creates a stable foundation for your irrigation strategy.
Consistent crop performance
With a 99.9% (LOG3) pathogen reduction rate, the system helps prevent diseases from spreading through irrigation water. This supports uniform plant growth and more stable, predictable yields.
Automatic operation
UV-C dosing is continuously adjusted based on measured water quality, allowing the system to automatically respond to changing conditions. Integration with Priva Connext and Compact CC reduces the need for manual intervention and improves the ease of use.
Chemical-free solution
Disinfection is achieved without additives or residues. This keeps the process safe for crops, people and the environment, while ensuring your water remains clean and suitable for reuse.

How it works

How Priva Vialux works

Water flows into the system from your source, where filtration removes larger particles. It then passes through UV-C reactors, where microorganisms are exposed to a controlled dose that inactivates pathogens.

Sensors continuously monitor water quality and adjust the UV-C dose accordingly. This ensures effective disinfection under changing conditions, after which clean, disinfected water flows into your disinfected storage.

Integrated control

The Vialux M-Line integrates with Priva Connext and Compact CC, allowing monitoring and control to be handled centrally. Through Priva Operator, you can access system performance, alarms and settings both locally and remotely.

The system automatically responds to changing water conditions, ensuring consistent operation without the need for manual adjustments.
