low chemical and energy consumption

very safe operation

standardised or custom made, economical and compact “plug & play”

RWO‘s family of wastewater treatment systems has been complemented to fulfil the new MEPC.159(55):• the membrane sewage treatment series SMT

(Submerged Membrane Technology)• and biological wastewater treatment series WWT-LC

(Low Chlorine)• MEMROD® process (MEMbrane Reactor Operation

Device) for larger capacities and custom-made systems

The technologies permit both black and grey as well as galley wastewater to be treated in a single reactor sys-tem. The effluent levels for the Membrane Bio-Reactor (MBR) based sewage treatment systems are better than the requirements of the International Maritime Organiza-tion (MARPOL, Annex IV) and both the future standards MEPC.159(55) and the USCG/Alaska-Rules 33.CFR 159.309.

systems for independent and reliable fresh water supply on Offshore Plat-

forms, FPSO andFSO vessels.

RWO’s network of more than 50 qualified sales and service stations around the world is taking care of our customers and provides after sales service at its best.

RWO benefits from its affiliation with the parent company Veolia Water Solutions & Technologies, the world leader in water treatment. With more than 130 subsidiaries in over 57 countries, the group specialises in water and wastewater treat-ment technologies for municipalities and indus-tries and generate a turnover of more than Euro 2.5 billion per year.

Within the group, VWS Westgarth are the wa-ter treatment specialists in Offshore Oil & Gas. World leaders in seawater sulphate removal (SRP) and expertise in produced water treatment, they focus on turnkey design & build projects.

RWO’s objective is to provide reliable and

long-lasting equipment. The reverse osmosis

plants are designed for automatic operation and

require little or no maintenance.

Oil/Water SeparationThe SKIT/S-DEB oil/water separator complies with the actual IMO Resolution

MEPC.107(49) using the combination of the highly effective open porous coa-

lescer together with a second stage emulsion breaking oil and hydrocarbon

polisher. Periodic back-flushing keeps the coalescer surface clean and offers

long lasting operation without requiring attendance and maintenance.

Our reverse osmosis units come with a built-in concentrate displacement, which will extend the membrane operation cycle. Additionally a chemical cleaning device is provided with the system in or-der to make cleaning of the membranes easy. RWO’s RO systems are completely assembled on a skid ready for operation.All SRO units are full scale tested with salt water prior to delivery. A work’s certificate showing all performance data comes with the equipment.The standard RWO reverse osmosis units feature:

automatic backwash filter

dosing system for scale inhibitor

fine filter

high pressure pump

high performance RO elements

salinity control

control panel with PLC for automatic operation
