The Priva Vialux lets you disinfect both large and small quantities of water. The Vialux M-Line series stands for a new generation of UV disinfection, based on mid-pressure UV which is unique in the market. The modular system can be customized to meet your company's needs. Depending on the scale of operation, two, four, six or eight UV disinfection chambers can be installed. The Vialux HD-UV series is based on high pressure UV with a single exposure chamber where all the monitoring is taking place. Both series can be operated as a stand-alone system via onboard controls or integrated as a sub-station of your (greenhouse) process automation system.
The design of both systems is very simple to make installation and maintenance as easy as possible. Minimum maintenance of the Vialux HD-UV needs to be carried out because of the single exposure chamber. The Vialux M-Line is especially designed that replacement of UV lamp, quartz tube and UV sensor can be done yourself, using a step by step illustrated manual; saving maintenance costs and downtime of your system.
The Vialux is fully automated and protected. At every system start, the UV transmittance of the process water will be measured to define the exact settings for the disinfection process.
This ensures that all harmful organisms are broken down without wasting energy through overcapacity. The temperature of the water remains virtually unchanged during the process, and the composition of nutrients and pH level are untouched. The system is protected in many ways: against lamp failure, overheating, dry run, surges, lows in the power network and more.
If you have a Priva Connext process automation system, the Vialux can be operated by this system. Priva Office Direct or onboard controls will give insight in your operation and advise you when maintenance should be executed. When connected to another brand of process computer, the computer can tell the Vialux when to start or stop working.
The Priva Vialux offers the lowest energy costs per disinfected cubic meter water, compared to other UV technologies. 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.
UV light and hydrogen peroxide complement each other, leading to better results for longer recirculation of water. Advanced oxidation with hydrogen peroxide removes growth inhibiting factors and crop protection agents, leading to cleaner waste water before discharge. It also helps to keep dripping lines cleaner.
Proper pre-filtration is the basis for long, trouble-free use of Vialux. Removing solid parts bigger than 25 microns is necessary, because germs can hide behind them making disinfection impossible. Filters smaller than 25 microns cause unnecessary flushing, energy loss and require more maintenance.
In addition, pre-filtration protects the Vialux against clogging.
Two pre-filtration possibilities are offered for the Priva Vialux:
