The introduction of Priva’s Vialux M-Line has put water disinfection using UV light within the affordable reach of every horticulturist. UV disinfection will enable major improvements to be achieved in the field of disease control, efficient water consumption and compliance with increasingly stringent food hygiene regulations.

The Priva Vialux M-Line decomposes all organisms that are alive in the irrigation water used in the horticulture industry, such as fungi, bacteria and viruses. This applies equally to fresh irrigation water and recirculated drain water. UV disinfection makes it possible to safely reuse water for longer periods of time. Furthermore, this will ensure a more efficient use of costly fertilising agents, as these will no longer be discharged into the drain.


The Priva ViaLux M-Line is based on medium-pressure UV technology, which is new to the horticulture industry. The system is made up of multiple disinfection chambers, whose number depends on the size of the farm or company. In this way, every grower will be able to order a custom solution and the system can cost-efficiently grow in proportion to the business.

As the UV lamp, quartz tube and UV sensor can be replaced by the growers themselves, there is no need to call in a technician for simple repairs. Maintenance is easy, too: rinsing with acid is enough to remove any deposit from the quartz tube. The Priva ViaLux M-Line can be used as a stand-alone system or linked to process computers from various manufacturers.


Every time the system is started up, the UV sensor determines the water’s UV transmittance and adjusts the disinfection process accordingly. This enables all hazardous organisms to be decomposed, while no energy is lost due to a capacity surplus. The system is protected against lamp failure, overheating, running dry and peaks and troughs in the electricity mains. According to Priva, the Vialux M-Line will allow growers to easily comply with all existing and future statutory regulations in the field of water and food safety, and at the lowest possible cost per cubic metre of water.
