RWO recently completed two installations of its next-gen advanced water treatment system (AWTS); the CleanSewage Membrane Reactor (CS-MBR), for Celebrity Cruises. The sewage treatment plant on the Celebrity Solstice-class vessels, Celebrity Silhouette and Celebrity Reflection, have been upgraded to the CS-MBR system, with an additional three orders placed to complete the fleet-wide upgrade.

RWO's CS-MBR is a sustainable biological treatment technology that has been designed to minimize a vessel's impact on the environment, achieve the highest standards for effluent discharge and perform well ahead of regulatory requirements.

The installations upgrade existing RWO MEMROD sewage treatment plants on board the Celebrity Cruises ships, reflecting new regulations for existing vessels operating in Special Areas and anticipate the expansion in regulatory parameters for such vessels from 1 June 2023*. The CS-MBR is fully type approved as conforming with IMO MEPC.227(64) including the standards of section 4.2 which addresses nitrogen and phosphorus removal.

Unique among shipboard AWTS solutions, the CS-MBR treatment process features submerged membranes in its final stage and can remove more than 99% of solids and bacteria, including microplastics and viruses.
