High-efficiency water treatment using light using a novel UV-light system

Controlling the movement of the water

There is a catch, however: this process takes place only in the immediate vicinity of the UV emitter a rectangular, flat glass element that is positioned in the reactor vessel. When power is applied to the element, the hydroxyl radicals form a thin reactive boundary layer only about 50 micrometers deep surrounding the external surface of the glass. In order to be sure no harmful particles escape untreated, the water must be controllably and verifiably directed through this boundary layer a genuinely tricky task. On the one hand, you have to make sure the entire contents of the reactor vessel is treated. On the other, the researchers would like to be as certain as possible that every single hydroxyl radical formed is also used for a chemical reaction. This is because the extremely reactive hydroxyl radicals are extremely short-lived. If no "fresh" molecules are found to react with during this time interval, the energy of the hydroxyl radicals goes unused. The experts in Stuttgart have been successful in controlling the movement of the water so exactly that all of the reactor vessel contents are reliably and highly efficiently treated.

The first industrial prototype, which has a through-put of 2.5 cubic meters per hour, will be shown by the researchers and their industry partners at the trade fair. "A certain amount of variation is normal, since the processing speed depends of course on the degree of contamination as well," explains Egner. To be sure the water is actually discharged only if its quality is impeccable, the unit is equipped with an additional safety mechanism. A sensor system is located right at the discharge port that monitors the water for harmful substances. The water is discharged only once impurities falls below a maximum permitted value. The entire unit is fully automatic and programmable for instance, it can be switched o
