Since 1991 we take innovations in the field of environmental technology onto the railways. We use systems and solutions that save resources and simultaneously increase the economic efficiency.You can take advantage of our comprehensive knowledge and our diverse product range in the field of mobile waste water treatment plants. Additionally we offer full service to cover all your needs. We design and manufacture all necessary collection tanks. Our scope of deliver even includes disposal equipment and water treatment plants for the drinking water supply of the dining-cars.Starting with the initial project meeting all the way down to the commissioning you will find specialists with extensive expertise – and excellent implementation skills for all customized solutions.
Green Light for Clean Water – the Bioreactor System of Protec Rail.Discover the benefits of wastewater treatment for rail traffic – and an investment that you will never regret.
Full Focus on Environmental Technology.Located in Hirschau, Bavaria, AKW A+V Protec Rail GmbH is a globally-active, medium-sized, privately-owned company.

TURNING WASTEWATER IN CLEAN WATER. AT FULL SPEED.WASTEWATER TREATMENT IN RAIL CARS – UP-TO-DATE.
The Protec BIOREACTOR. The (bio)logical answer to conventional collection tank systems. Less efforts, lower operational costs – and higher availability of the rail cars.The mobile small wastewater treatment plant impresses through higher economic efficiency in rail traffic. Protec Rail has developed the »Bioreactor« – an unprecedented biological toilet system.The Bioreactor has significantly lower operational costs compared to closed collection tank systems. Mainly, because of the appreciable increase in disposal intervals.Using our Bioreactor you also take advantage of our comprehensive know-how in the field of waste water treatment – in a system that was specifically designed for the railway sector.
FACTS ABOUT THE BIOREACTOR
The Bioreactor – the »High Performance Small Waste-water Treatment Plant« for the installation in rail cars
– the system treats the waste water of the train toilet in the travelling train
– the purified water can be discharged on the railroad tracks
– the system increases the time between disposal intervals and reduces the service requirements
– savings in infrastructure and operational costs
– required installation space comparable to conventional collection tank systems
– easy and environmentally friendly operation without using chemical or auxiliary agents
Proven Performance has no limits:Many European railways rely on the competitive edge of the Protec system.

In principle, the Protec system is designed using the following elements:
– solids chamber
– liquids chamber
– hygienization unit
– controls and display

B I O R E A C TO R – F U N C T I O N A L I T Y
THE FUNCTIONALITY
SOLIDS CHAMBER
The waste water flows from the toilet to the filter basket and this filter basket retains the solid components. The mechanically treated waste water seeps to the fluid reactor because of gravity (vertical bioreactor) or by using a pumping device (underfloor bioreactor).
LIQUIDS CHAMBER
Using ventilation pipes, oxygen enters the fluid reactor and flows through the so-called fixed bed area, on which a biofilm has grown. After a defined period of time the biologically treated liquid is carried to the thermal hygienization unit.
DRAINING OF THE RESIDUAL WATER
Ultimately, this results in a liquid that is drained onto the rail tracks when travelling at a speed of > 5 km/h.The liquid draining of stationary rail cars is prevented, but the toilets can still be used without any restriction at the railway station and when the train is not moving.

MODELS OF THE BIOREACTOR
In general, there is a distinction between a vertical design and an underfloor design of the Protec system. The design of the plant can be modified according to the rail car specific installation site.
Examples of a vertical and an underfloor reactor:
Underfloor Reactor EW IV Vertical Reactor STB 21

INSTALLATION OF OUR BIOREACTOR
Vertical: The treatment tank is installed in the rail car directly after the toilet system.
Underfloor: The Bioreactor is installed under the car body or below the toilet or somewhere near.

ADVANTAGES
– long disposal intervals (between 2 and 6 months)
– high availability of the rail car
– economic benefits with respect to the LCC values
– low requirements on the disposal equipment, fewer service stations
– independence from infrastructure, notably for international traffic
– no „external“ waste disposal costs
– environment-friendly
– no addition of chemicals or additives
– no emergence of explosive or combustible gases
A CLEAR DECISION. ESPECIALLY IN TERMS OF EXPENSES.
Depending on the situation the higher acquisition costs of the biological system are amortized after just a few years because of the favorable operating costs and the small expenses for the waste management infrastructure.
