Water treatment processes
The treatment of drinking water is a matter of trust. Consequently, in the Hydro Group water treatment means much more than just providing components. As a system supplier, we initially tackle the existing water problem, and only when we have done that do we make a decision about the necessary treatment process. Filtration enables not just turbidities to be removed from the water but also iron, manganese or arsenic. This often requires pretreatment such as oxygen enrichment oxygen enrichment.
Using ozone (ozoning) disinfects and oxidizes raw water, thereby enabling it to be treated for use as drinking water. Ozone bio-filtration has become established as an efficient process for treating surface waters that contain humates. Central softening of drinking water as early as at the waterworks enables pleasantly soft water to be produced at low cost to the consumer. Membrane processes such as ultrafiltration or nanofiltration/reverse osmosis are setting new standards - particularly when combined with other processes (hybrid processes).
