I have written previously about the dangers of airborne bacteria and their role in causing many cases of bottled water contamination.
During production, with efficient positive pressure airflow, this should not be a problem. However, during the night and at the weekend, bacteria, dust, pollen particles and mould spores will settle on your washer, filler, cap chute and other objects in the plant. Start up can therefore be a vulnerable time for your operation.
An effective solution uses UV-C technology to destroy airborne micro-organisms. Untreated air is drawn through a particle filter, removing dust and pollen particles. The air then passes over a 36W compact UV-C tube positioned within a baffle chamber.
This chamber prevents any UV-C light escaping the unit, whilst ensuring all the air drawn in passes over the tube. Treated air is then expelled out of the unit.
The unit has been independently tested to prove its effectiveness against the most common airborne bacteria, yeasts and moulds.
More recently, high tech devices have appeared on the market using cold plasma technology which effectively destroys micro-organisms in the air by generating transient oxidising chemicals.
