Emulsion Splitting and Filtration Unit

Emulsions and particles complicate the treatment of bilge water and increase the need for oily water separators. To relieve the emulsion splitting parts of OWS-units from particles and wastewater and save consumables, a pre-treatment can be installed.

RWO’s splitting and filtration unit, SFU, is able to pre-treat difficult bilge waters and meet individual requirements. It uses a fully automatic three stage process, consisting of the addition of a special splitting agent, slow oil separation from the water and a filtration unit to remove all particles. The system even allows operators to switch off the oily water separator and use the SFU system as a standalone filtration unit.
