Water treatment with oil-free compressed air

clean - reliable - economical

Sustainable water treatment with oil-free compressed air

If water contains too much iron and manganese, not only the taste is affected: deposits, germs in the water-bearing pipe systems as well as bacterial growth are also the result . The German Drinking Water Ordinance (TVO) therefore prescribes, among other things, certain threshold values for iron, manganese and other chemical components in water.

With our oil-free compressors the required compressed air for the water treatment can be produced and thus any contamination with oil is excluded. Drinking water treatment is carried out using various physical, chemical or combined methods. The applied method depends on the impurities or minerals the spring water may contain. Some of these methods require either a specific gas or compressed air, which serves as aeration to remove iron or manganese by oxidation in drinking water production.

The design principle of Dürr Technik's oil-free compressors prevents contamination of the water with oil components and thus guarantees the quality of the compressed air produced - a decisive factor in water treatment.

Individual compressor solutions for your water treatment plant

Thanks to our many years of experience in water treatment, we can offer you tailor-made system solutions. Besides the actual compressor unit, these include the construction of complete stations with the corresponding pressure vessel 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.

Ozonisation - 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.
