The Primozone ozone technology is utilised at many sites worldwide in the treatment of waste and municipal water. Ozone can be injected into the water as a disinfectant or used as an oxidising treatment to remove colour and taste from humus.
Ozone oxidation is the most effective water-treatment process available today. It ecologically benign as ozone is a natural gas that breaks down into oxygen within a short period of time with no residues. Ozone has a high oxidation potential (2.07V), i.e., its potential to react with other substances. The oxidation potential of ozone can be measured by the redox potential and is five times more powerful as an oxidizing than oxygen and about twice as oxidizing as chlorine. Ozone has a well-documented kill rate of microorganisms such as fungi, bacteria, and viruses. In addition to being able to eliminate microorganisms through disinfection processes, ozone can be used to control taste, odour, and colour. It can also be used for flocculation of organic material, which simplifies subsequent mechanical filtration.
The MD at Ålands Vatten AB, Mr. Christian Nordas says “When the old ozone generators were worn out, we decided to replace them with a new generation of ozone generators from Primozone. The Primozone ozone generator system is very reliable and has since the installation worked very well indeed. The production of both ozone and oxygen gas exactly follows the fluctuations we have in the water flow which means that the energy consumption has decreased substantially compared with the old system. We are very happy indeed.”
