For more than 30 years Roediger has been supplying reliable and individual systems for the wash water and rinse water treatment of train exterior washing systems.
As one of the world’s leading railway operators, Deutsche Bahn (DB) understands the importance of maintaining clean and efficient trains to ensure safe and comfortable journeys for millions of passengers.
With a vast network spanning across Germany and beyond, DB’s fleet of trains requires regular cleaning. More than 7,200 kilometres of DB trains and suburban trains are cleaned every year – an area of 2.3 million square metres!
Roediger provides eco-friendly practices, including the implementation of innovative water treatment and reuse methods to allow environmentally conscious operations of the train-washing plants. These water treatment systems for train washing plants focus on sustainability, ensuring that water consumption is optimised without compromising on cleanliness.
Water Recycling System
Roediger provides advanced water recycling systems that are of central importance for eco-friendly train washing plants.
These systems capture, filter and treat the water used during the cleaning process, enabling its safe and efficient reuse. Instead of allowing thousands of litres of water to go to waste after a single wash, the treatment process ensures that the same water can be used for multiple cleaning cycles. The majority of the washing and rinsing water (up to 90%) can be reused.
A high water-recovery rate enables the economical operation of the train washing plant and is made possible by a cascade-like interconnection of the individual water circuits.
Roediger water technology automatically controls freshwater demand, water recycling and wastewater treatment.
The sophisticated Roediger water treatment and purification technologies guarantee that the recycled water meets the highest standards of cleanliness and safety.
