BioUnit - The Bioreactor toilet cleaning system

The BioUnit is a special cleaning device to service advanced bioreactor toilet systems on-board of trains and rolling stock vehicles. The BioUnit is capable to automatically dispose of the contents of bioreactor sytems as well as providing cleaning cycles to maintain a safe long-live system operation. Beside the regular cleaning procedures required every 2-3month, special chemical and descaling cycles can be carried out to perform a full system recovery of the bioreactor waste water treatment unit.

The BioUnit system can be provided as a mobile or stationary solution and can be used both indoors and outdoors.

Thanks to the modularity of the system, different cleaning programs can be preselected to meet the cleaning requirements of the bioreactor model which shall be serviced.

Some of our products for the railway, bus or marinas sectors can be delivered as stationary or mobile installations. As stationary installations, the BioUnit, PierPump or RoadPump are totally fixed on the ground, with stainless stell housing and optionally winter protected. As mobile units, they can be installed in a mobile handcart to be able to use them everywhere.
The BioUnit is equipped with a descaling device to reduce the level of clay in the water.


A remote control is used in some Vogelsang systems, as ReelUnit, CabinetUnit, BioUnit or TUnit, to control the right operation of the system. It allows, for example, valves to be opened and closed in the ReelSystem. Optionally, the BioUnit can be equipped with a remote control module, network connected or online, to adjust all cleaning parameters of the complete system.
The BioUnit or some of the MobileUnits from Vogelsang can include optionally an active carbon exhaust air filter unit for cleaning the tank exhaust air.
To ensure safe operation even in subzero temperatures and to protect the cabinets or pumps, electric heating elements as well as heating pipes can be used optionally. The heating system is equipped with temperature sensors and an automatic temperature control.
The BioUnit can be optionally equipped with a Vogelsang twin-shaft grinder, XRipper, when the solid content is very high. The XRipper grinds all kind of solids, making easier the further pumping or processing of the waste water.

Optionally, the WaterUnit, BioUnit or TUnit can be equipped with a data acquisition system: all the filling and flushing processes can be logged, saved and transferred via wireless standard.
