Disinfection Systems and Oxidation Systems
ProMaqua offers its customers the benefit of all standard disinfection methods from a single source and as part of the Smart Disinfection system: UV treatment, ozone, chlorine dioxide, electrolysis, dosing of liquid disinfectants.
Our specialists, all with detailed sector knowledge, are able to put together the optimum process for any particular application. To select a suitable disinfection or oxidisation method, both costs and benefits must be weighted against specific requirements. In this respect, the following points are considered:
- Disinfecting or oxidising strength
- Cost for the chemicals to be used
- Energy expense
- Formation of disinfectant by-products
