Disinfection and Oxidation Systems
ProMinent customers are offered the advantage to get all current disinfection methods from one hand: UV treatment, Ozone, Chlorine dioxide, Chlorine electrolysis, dosing of fluid disinfectants.
Our specialists can thus compose the procedure which is best suitable for the respective application. For the selection of a suitable disinfection and oxidation method, effort and benefits for the specific requirements are to be examined first. Here-fore, among others, the following topics are paid attention to:
- Strength of disinfection or oxidation
- Efforts for the chemical to be used
- Energy input
- Generation of disinfection by-products
