RWO advances sewage treatment system
CleanSewage Bio’s access on one side allows it to be fitted without maintenance space on both sides and at the back of the unit, leading to claimed space savings of up to 25% against competitive models depending on capacity.
An at-a-glance status control uses the internationally understandable traffic light principle (three LED lights) to signal if the system is running properly. Every parameter can be adjusted manually to the individual route, enabling savings in consumables and reducing total cost of ownership.
RWO has also improved the treatment process with details that make the handling of the plant much more comfortable for the crew. The system uses a biological two-chamber process; with chlorination used only in the last stage. The chemicals used are non-flammable and employed by all ships on a daily basis.
The system is also substantially more hygienic, with biofilm carriers of the Moving Bed Bio Reactor (MBBR) clustered in baskets that can be easily removed separately from the organic load. The sieve to hold back solids is cleaned automatically and can be emptied without contact with faeces, while non-degradable solids can be pumped out without the sieve having to be disassembled.
Florian Schmidt-Bormann, chief sales officer, said: “We are pleased to present a system which combines the success of our former wastewater series with some new features that even our customers may not have thought about yet. We’ve listened carefully to our partners and identified needs that CleanSewage Bio adapts to in the best way possible.”
