Ozone
As the most powerful oxidant that can be used in water treatment, ozone makes a broad spectrum of applications possible.
Outstanding disinfection action against:
- Bacteria and viruses
- Fungi and parasites
Oxidation of undesirable inorganic substances in the water:
- Iron and manganese
- Arsenic
- Nitrite and sulfide
Oxidation of undesirable organic substances in the water:
- Strong-smelling and strong-tasting compounds
- Humic substances and other compounds which affect the colour of the water
- Cyclic hydrocarbons
- Trihalomethanes, chloramines and other chlorine compounds
Microflocculating action
-
After oxidation with ozone, substances and colloids dissolved in the water become insoluble and can be filtered Significantly less environmentally-harmful by-products occur in the production and use of ozone, than with other comparable oxidants and disinfectants. As a highly reactive gas, ozone is produced on site, and introduced to the water directly, without interim storage. Because of its high reactivity, ozone decomposes into oxygen again in the water, with a half-life of several minutes. All components of an ozone handling system must be perfectly matched with each other and with the planned application, to achieve an optimal relationship between ozone production and effect.
For every new project, our engineers draw on experience , in the following applications:
Drinking water supply
- Oxidation of iron, manganese or arsenic
- Improvement in appearance and taste
- Disinfection
Food and beverage industry
- Disinfection of mineral water
- Disinfection at the rinser in the beverage industry
- Disinfection of production water
Swimming pools
Reduction of chloramines and trihalomethanes, so avoiding typical swimming pool smell
- Crystal-clear water as a result of microflocculating action
- Reliable microbiological barriers in therapy pools
- Reduction of investment and operating costs through the possibility of reducing the circulating power and throttling the fresh water inlet
Industry
- Cooling water treatment
- Combating legionella in cooling water circuits
- Disinfection of process water
- Removal of odorous substances in air scrubbers
Design criteria
For optimal operation of a water treatment system using ozone, it is essential that all
components are carefully matched:
-
Ozone generation:
Selection of a suitable ozone plant is not only determined by the required quantity of ozone/hour, but also by other limiting conditions such as the nature and temperature of the cooling water and the environmental conditions, etc. -
Mixing:
To design the mixing system, the parameters of the water to be treated such as flow rate, back pressure, etc. are required first.. -
Reaction tank:
Each individual application will determine whether a reaction tank is required, and if so, its size and the type of equipment required. -
Residual ozone destruction:
Similarly, the choice of the suitable ozone destructor is determined by the ozonisation application. For example, catalytic residual ozone destructors cannot be used in swimming pools, because of their sensitivity to chlorine.
