The portfolio of Bremen-based water treatment manufacturer RWO has a new family member. CleanSewage Bio is an attack on the wastewater treatment market, one-side-access to the system gives significant space savings while great efforts were put into an easy and understandable handling concept, the developer said.

Together with a very compact system design, the one-side-access of CleanSewage Bio offers space savings in the engine room, allowing planning without maintenance space at both sides and the back of the system.

To ease operation and bring failure rates to the lowest possible, RWO has developed an intuitive status control which enables checking the plant’s status at a glance. By the internationally understandable traffic light principle three LEDs signal if the system is running or an intervention is necessary. Inside the switchbox, every aggregate can be controlled manually to adjust the settings of the system to the individual travel route – a feature that enables savings in consumables and lowers total cost of ownership.

Besides that, RWO has improved the treatment process with some details that make the handling of the plant much more comfortable for the crew. The system works according to the proven treatment principle with a biological two-chamber process; only in the last part is chlorination necessary. The chemicals used are non-flammable and employed at many places in the ship’s daily routine. In terms of maintenance the system is more hygienic.

The biofilm carriers of the Moving Bed Bio Reactor (MBBR) are clustered in baskets, they can be easily removed from the tank and do not have to be taken out by hand or broom together with the organic load. The sieve to hold back solids is now cleaned automatically; it can be emptied without contact with faeces. Non-degradable solids can be pumped out without the sieve having to be disassembled. The plant’s own discharge pump is suitable for this.
