Water treatment

Reverse osmosis systems

Spring water can be desalinated and filtered using reverse osmosis. In our reverse osmosis systems, water flows under pressure, parallel to the membrane's surface, whereby part of the water penetrates the membrane. Depending on the type of membrane, salts, organic substances, dissolved particles and the like remain behind in the main water flow. In addition to salts, bacteria (incl. Legionella bacteria) and viruses can be blocked by applying reverse osmosis. A wide range of standard systems is available; however, we can also always design a customer-specific system for you.

Disinfection systems (Priva HD/UV Vialux)

Water disinfection in the horticultural sector is essential to achieve healthy crop growth. The Priva Vialux HD/UV was specifically developed for the pre-treatment and post-treatment of rain, surface and drain water. This saves you water, fertilisers and energy. The system operates on the basis of high-pressure UV disinfection.

The Priva Vialux HD/UV system can be used to disinfect large or small quantities of water with UV light. A unique property of the Priva Vialux is that it can render moulds, bacteria, nematodes and viruses harmless, including specific viruses such as the Pepino Mosaic virus. Because the system modifies the DNA of these microorganisms, they die out.

You can opt for selective or total HD/UV disinfection. You can set the system to administer different doses depending on the crop and the type of pathogens. Because the system is fully automated and secured, water disinfection with the Vialux is highly reliable and controlled. During the process, the water's temperature stays virtually the same. The composition of nutrients and the pH value also remain unchanged. De Priva Vialux HD/UV is the only UV disinfection system whose effectiveness has been demonstrated by Wageningen UR.

The Vialux is available in multiple basic versions with increasing lamp strengths and capacities. Consisting of a single exposure chamber, a single UV lamp and a single UV-C meter, the Vialux's construction is very simple. As a result, the system requires very little maintenance.
