Westfalia is a leading multinational supplier of avocados to international markets. Before ArcAqua, Westfalia applied Prochloraz to its avocados, ensuring a residual level of less than 5 mg/kg. European markets, however, demanded far lower residual levels. In response, Westfalia attempted to improve sanitisation with cholrine dioxide. This had to be abandoned, however, due to the resulting corrosion of its pack-line, and formation of potentially toxic gas.
In March 2016, Westfalia installed ArcAqua, with over 9 months of compelling data to support their decision.
The most interesting finding was that before ArcAqua, during the course of a day, the chlorine treatment progressively became less effective (as the brushes became more contaminated). Not only was ArcAqua ozone more effective than chlorine dioxide, the ArcAqua system continually sanitised the brushes and therefore became more effective at microbial reduction as the day progressed.
