Who is "DVZ"

For over 40 years, “DVZ” is a synonym for tailor made, sustainable and holistic solutions for waste water treatment in the maritime sector.

More than 10,000 of our systems “MADE IN GERMANY” are in reliable service on board a wide variety of ships, thus making their contribution to preserving the ecological balance of the seas and oceans.

Innovative key technologies such as the highly efficient bioreactor DVZ-JZR (Jet-Zone- Reactor) and the unique membrane units of the DVZ-BMSU (Biomass Separation Unit) raise our systems to a new level for waste water treatment on board.

We offer turn key systems that are tailored to the needs of our customers. Thanks to a highly compact and modular design (process stages can be divided), our systems find their place in the engine room even in cramped conditions.

We are equally at home in the new-building sector as we are in replacing or partially supplementing existing systems (refitting).

"Marine protection is climate protection"...

A statement that we can endorse and from which we can derive our ambitions to contribute to this. It is essential to keep our marine ecosystem in balance.

Our ambitions here are quite simply defined: To offer innovative solutions and systems that reliably and safely perform their service. We extend this by defining our claim to not only meet the existing regulations for the discharge of treated ship sewage, but to continuously undercut them in their limit values.
