Mobile tunnel cleaning train

Wastewater treatment directly on track


The mobile wastewater treatment system is integrated in a tunnel cleaning train and is the first of it´s kind worldwide. The system is able to recycle the wastewater of the cleaning process immediately on the spot.

The cycle approach of our system allows the efficient use of the tunnel-cleaning-train also in exposed areas, with no availability of fresh water or possibilities of waste disposal.

Operating principle

The wastewater is pumped from the suction dredger in the wastewater tank and goes directly from there to the water treatment system.

During the multi-stage filtration process (flocculation / fine filtering) the solids are locked out.

The treated water is carried to the fresh-water-tank and can immediately be re-used for the cleaning- process.
