  • Russian River Register certifies RWO's oily water separator

    RWO's oily water separator SKIT-S DEB has gained approval from Russian River Register RRR and therewith adds another inportant certification to a long row of successes for RWO's classic.

    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 SKIT/S-DEB type uses a combination of highly effective open porous coalescer with automatic backfl ushing, together with a second stage emulsion breaking oil and hydrocarbon polisher.
    The periodical backfl ushing keeps the coalescer surface clean and offers long lasting operation without attendance and lowest maintenance, according to IMO Resolution MEPC.107(49).
    The excellent and long experience with the RWO coalescing type oily water separator guarantees a high performance standard.
