Oily Water Separation

With more than 15,000 systems sold, RWO is the world leading supplier of Oily Water Separators

Systems with excellent performance

OWS-COM

RWO has more than 40 years of experience, which manifested itself in the excellent performance of our oil/water separators, guaranteeing a consistent high performance standard. More than 15,000 ships have already been equipped with this efficient system. 

The OWS-COM oily water separator complies with the IMO Resolution MEPC.107(49) by using a combination of the highly effective open porous coalescer together with a second stage emulsion breaking oil and hydrocarbon polisher.

RWO's oil water separation technology is available with additional features: Complete your bilge water treatment systems with a clean Bilge monitoring system splitting and filtration unit, our adsorber cartridges or the BilgeEconomiser!

Advantages at a glance

  • Extremely compact: suitable for newsbuilds and retrofit
  • Easy to install and maintain
  • Extremely economical: regular water checks ensure that a second stage of separation is bypassed whenever possible
  • Suction type: preserves pump from attrition
  • Extremely safe: Oil Monitoring device activates recirculation mode if required

How it works

OWS-COM

The safest way to discharge bilge water over board: CBM-LINK

CBM-LINK is an intelligent Clean Bilge Monitoring System designed to help make on-board water treatment significantly more efficient and cost-effective. The system comprises the two CBM and LINK systems that fit seamlessly together.

CBM acts as the final control mechanism before bilge water is discharged. The compact system has a 3-way valve, which allows the inflow of treated bilge water and water that is normally uncontaminated, such as condensate from air conditioners. The system independently monitors whether, as prescribed by IMO Resolution MEPC 107 (49) for particularly sensitive sea areas (PSSA), maximum oil content of 0, 5 or 15 ppm in the water being discharged is complied with and automatically transfers it either directly overboard or to the bilge water tank for further treatment. This significantly reduces the quantity being treated by the bilge separator. Additional assurance is provided by a 2-point measurement of oil content. All modes of operation, valve positions, system configurations, ppm levels and OMD information can be visualised and read via digital and analogue interfaces. 

The system is tamper-proof and prevents the deliberate or unintentional unlawful discharge of contaminated water. Ship operators can thus avoid horrendous fines.

LINK is a software system which provides detailed information about the operation of the system as well as the composition of the bilge water. The information can be visualised in real time, enabling timely adjustment of system modes. Connected to the ship's communication system, the system is able to access GPS coordinates. Based on the data collected during the test phase, future features will be developed to further optimise operation of the system. In 2019, for example, it should be possible for LINK to independently determine when filter changes are necessary, making planning for maintenance work considerably more efficient and minimising operating costs and downtime.
