We have published a book about Black and Grey water that covers everything from water chemistry to the regulations and also address the challenges with this waste stream onboard a vessel and also the proposed corrective measures to overcome the problems.

We have seen so many vessels equipped with treatment units that cannot meet the effluent requirements and the Dutch shipping inspectorate conducted a study some years back where none of the 32 tested treatment plants where compliant.

We use the Black and Grey water book during seminars and workshops and please contact This email address is being protected from spambots. You need JavaScript enabled to view it. if you are interssted in learning more on the topic or if you would like a presentation or a seminar.
