Adopting Danish chemical-free methods in Hungarian waterworks

The water treatment technology used most often in Denmark to convert groundwater into drinking water is aeration and filtration for removal of iron, manganese and ammonium. This is a chemical-free and natural process using just compressed air as the oxidation media. This treatment method is now also used in Hungary for the 12.000 inhabitants of Tolna, a city 135 km south of Budapest.

The new waterworks has a good working environment with no wastewater problems and safe and easy operation, and the citizens now enjoy superior drinking water free of chemicals. This is a break with tradition, because as all drinking water in Hungary has previously been treated using sand filters and chemicals – the Tolna waterworks is the very first that has stopped adding chemicals.
