Water treatment with oil-free compressed air

clean - reliable - economical

Sustainable water treatment with oil-free compressed air

When water contains too much iron and manganese, not only does it taste different, but also results in deposits inside the pipelines, where it contributes to the growth of germs and bacteria. Therefore the water authorities stipulate the allowed levels of these chemicals.

Our oil-free air compressors can meet the required air quality that is necessary for certain water treatment processes. By design, Durr Technik`s air compressors are oil-free, thus they guarantee a consistently high quality air supply, which is an important factor in the water treatment processes.

Besides the actual compressor unit, these include the construction of complete compressor systems with the corresponding air tank and all necessary fittings, supplemented by a comprehensive range of accessories. The accurate coordination of all components ensures optimum interaction.

Water treatment process: iron removal / manganese removal

Compressed air is added to the water using oil-free compressors from Dürr Technik. This contact oxidizes iron and manganese, resulting in clean water.

Ozonation - as part of oil-free water treatment

A method for sterilization and disinfection by the addition of Ozone as oxidizing agent. For ozonization, oil-free compressed air supplied by Dürr Technik's compressors is required, and is deployed. During ozonisation, the reactive effect of Ozone causes a very rapid inactivation of bacteria and viruses.

Pneumatic functions in water technology

The oil-free compressors from Dürr Technik are also used for actuating cylinders, switching of valves and other pneumatic functions such as pressure compensation.
