Total Water Management
RWO – Marine Water Technology is one of the leading suppliers for water and wastewater treatment systems on board ships and offshore installations.
Bilge Economiser
Aboard every ship, so called ‘clean drains’ are treated in oil-water separation systems and strain machines and resources. These clean drains usually consist of leakage of and condensate from equipment used for seawater, fresh water, steam, air conditioning, etc., which are usually not contaminated by oil.
Emulsion Splitting and Filtration Unit
Nowadays Oily Water Separators are able to treat almost every sort of bilge water and ensure a safe and environmentally friendly approach to handling waste water. But changing compositions and concentrations, the potential to emulsify as well as the increasing presence of particles and wastewater in the bilge water often complicates the entire process.
Grease Trap
RWO’s grease traps are working on the principle of gravity; Substances heavier than the carrying medium (water)settle down while lighter substances, such as grease and oils, rise. Long flow paths and slow flow velocities support
the working principle. Galley wastewater pre-treated in the grease trap can then be fed to RWO’s wastewater treatment systems for further and final treatment.
OWS – COM Suction Type Oily Water Separator
More than 14,000 ships have already been equipped with RWO’s oily water separators since RWO started its business in 1975. As its predecessors the OWS-COM uses a combination of highly effective open porous coalescer with automatic backflushing, together with a second stage emulsion breaking oil and hydrocarbon polisher.
Sewage Treatment
The RWO WWT-LC sewage treatment plant is a 3-chamber process. The heart of the plant is a well-established Moving-Bed Biofilm Reactor (MBBR), where organic matter is degraded into carbon dioxide and water by microbial activity. The air required for this process is generated by an integrated blower. The aeration stabilises at the same time the biomass and prevents harmful and dangerous gases from forming, such as methane and hydrogen sulphide.
