The Priva Vialux UV systems are designed to effectively disinfect irrigation water in horticulture. By using high density UV-C technology for disinfection, the result is a guaranteed safe reuse of (drain)water and optimal efficiency in water and fertilizers usage. The Priva Vialux HD-UV series is based on high pressure UV. It has a single UV-reactor, with full control. A system with over 20 years of experience in high-tech horticulture. The Vialux is available in a number of versions with increasing levels of lamp power and capacity.

Functioning of Priva Vialux line

The Priva Vialux-Line disinfects water with UV-C light, destroying all existing pathogens like fungi, bacteria and viruses. The system can be applied for (pre-)treatment of water, recycled drain and discharge water.  The water to be disinfected is passed through the stainless steel exposure chamber at a defined speed. The high-pressure UV-C lamp is located in this chamber. The lamp, enclosed in a quartz tube, irradiates the water passed through the chamber with UV-C. A wiper mechanism working together with minimal acid dosing cleans the quartz tube. The high power of the HD/UV lamp means that one lamp in one chamber is sufficient, whereas other UV systems require between ten and thirty lamps and chambers. The UV-C intensity is measured by a UV-C sensor. A computer controls and protects the whole disinfection process and ensures that the chosen UV-C dose is delivered. UV disinfection allows continuous recirculation of irrigation water in a safe way. As a result, expensive fertilizers are not flushed down the drain and do not contaminate the environment.

Advantages of Priva Vialux water disinfection systems

• No increase in water temperature
• No change in the composition or pH of the water
• Completely automatic, safe and reliable
• Automatic cleaning
• Power level control and water flow control
• Automatic T10 calculation
• Simple design, one exposure chamber, one UV lamp and one UV-C measurement
• Low investment and operating costs
• Suitable for the drain water from your growing medium
• Blending of drain and sump and/or surface water
• Disinfection of drain and surface water alternately
• Also suitable for Ebb and flood and NFT water

UV water disinfection

The active UV-C, which has a wavelength of approximately 200-300 nanometres, alters the DNA of micro organisms, such as microbes, bacteria and moulds, destroying them in the process. UV-C light also makes viruses inactive.The permeability of UV-C light, called the T10 transmission, is an important factor in the process. T10 transmission above 10% facilitates water disinfection.

Safety
All Priva Vialux systems are fully automated and protected in many ways: against lamp failure, overheating, dry run, surges, lows in the power network and more.

Short payback time
Through the reuse of water, you can realize substantial savings on water and fertilizers. In most situations, the Priva Vialux has a payback time of less than three years.
