Soft water for the Roman city of Carnuntum

The tap water in Petronell-Carnuntum, the town where the Romans once settled, comes from deep wells in the Danube floodplains and is rich in calcium and magnesium. However, too much calcium in the water also brings numerous disadvantages: dirty glasses, defective appliances, higher consumption of detergent and dry skin when showering. AGRU supplied numerous components made of PP for a desalination plant that feeds soft water into the pipelines.

Natural filtration in detail

For the new natural filter plant, a hall with a size of approx. 60 m x 30 m and a height of up to 11 m had to be built. Inside there is highly complex technology. The well water passes through 4 x ultrafiltration, 4 x reverse osmosis, 6 x activated carbon filtration and 4 x UV disinfection. This not only effectively removes hardness constituents, but also significantly reduces other undesirable ingredients, such as nitrate. Leyrer & Graf used 700 linear meters of AGRULINE pipes and fittings up to 560 mm for underground pipelines. Container builder Bilek & Schüll supplied numerous containers and tanks made of AGRU PP sheets. Here, the material PP scores with its higher strength and rigidity. The plant has been in operation since the beginning of this year. When completed, it will produce 300 l/s of soft drinking water.
