Mellifiq ozone solution provides insight into cleaner drinking water

Trollhättan Energi is a utility company owned by the city of Trollhättan. Their mission is to supply the city with e.g. electricity, internet fiber connections and clean water. One of their newest projects involves building a new drinking water processing plant with 1500 cubic meters per hour to supply the city with potable water. Designing and building such a water production site can take many years to realize.

Looking at the best available technologies, ozone was chosen as an extra microbial barrier. Several technology combinations were now to be tested in order to find the right recipe to treat the unique water composition in Göta Älv.

An Ozonetech RENA Vivo ozone system was chosen for performing two separate pilot projects at two different extraction sites. Mellifiq was able to quickly dispatch two fully equipped systems for two years total rental time. As even the smallest model in the RENA series include all necessary features for a fully functioning water ozonation process, the design can now be scaled to fit the full scale installation.
