A 48-Lamps-VitaLite

A 48-lamp VitaLite was recently put into operation at the Canadian propagation nursery Ontario Plants. This VitaLite is equipped with 48 UVc lamps which are switched on using special electronic starters.

It was decided to use the ADS type irradiation chambers for this project, which were especially designed for water with a high transmission value. The unit treats the water at a capacity between 50 and 100m³/hour, depending on the water quality measured by the system and the desired Uvc dosage of 150mJ. For this purpose, the system pump is fitted with a frequency controller which is operated based on the transmission value measured. An additional feature of the control software is that it minimizes power consumption. The system is also equipped with a small acid pump which automatically cleans the quartz tubes, so the pH of the water to be disinfected can be adjusted quickly to the desired value.
