About us
For more than 40 years, "DVZ" is synonymous with sustainable and holistic waste water and sewage treatment solutions. Our systems are in service aboard Yachts, Cruise Ships, Navy Vessels, Offshore Platforms and Vessels of all kinds around the globe.
More than 10,000 of our Waste Water Treatment Systems, Oily Water Separators, Fat Traps, Collecting Tanks and Pump Stations already contribute to the balance of the seas.
Our patented key technologies, the DVZ-JZR® Jet Zone Reactor and the unique DVZ-BMSU® Membrane System, ensure reliable, effective waste water treatment, paired with high purification and easy maintenance.
In-house development and a production with a very high vertical range of manufacture in Germany guarantee advanced and innovative technologies for clean oceans.
Thanks to their high flexibility, the separability of individual process steps and low space requirements, our systems fit into given spaces and can also be integrated into existing systems in order to expand and optimize them. Regardless of whether if it's a New Build or a Retrofit.

DVZ-JZR "BIOMASTER"® - CRUISE
DVZ-JZR "BIOMASTER"® CRUISE - ADVANCED SEWAGE TREATMENT SYSTEM
THE PERFECT ADVANCED SEWAGE TREATMENT SYSTEM, TAILOR-MADE FOR CRUISE SHIPS!
Scalable, divisible and customisable like no other, the DVZ-JZR “BIOMASTER”® system is the perfect solution for high passenger numbers such as on cruise ships.
Due to the variable number of Jet-Zone-Reactors DVZ-JZR and Biomass Separation Units DVZ-BMSU, the system can easily be scaled and adapted to the requirements on board. Because of the divisibility of the biological reactor stage and the membrane units, the DVZ-JZR “BIOMASTER”® also adapts seamlessly to the available space in the ship’s hull and is therefore perfect for retrofitting.
THE KEY FEATURES
Type Approval in accordance with IMO Resolution MEPC.159 (55), IMO Resolution MEPC.227 (64) incl. clause 4.2 (P and N removal) and MARPOL Annex IV
Fulfils the stringent requirements for Great Lakes, Alaska and Special Areas
Highly flexible and scalable. Process steps and system components can be divided and assembled separately
Highly efficient Jet-Zone-Reactor DVZ-JZR with immense Biomass concentration tolerance, defined retention time and high purification effect
Biomass Separation Unit DVZ-BMSU with the unique and indestructible Stainless Steel Membranes; mounted outside for easiest cleaning, changing and maintenance without system opening (min. two membranes)
Ultra Compact Stainless Steel Design with smallest possible footprint (up to 75 % space saving compared to conventional ship sewage treatment plants)
No chemicals for treatment or disinfection necessary
Neither internal moving parts, nor sensitive against shock, vibration and movement
DVZ-FSU “OILCHIEF”® - OILY WATER SEPARATOR
Reliable and proven oil-water separation for the treatment of oily bilge water has been firmly associated with the DVZ brand since its foundation.
For this purpose, our systems are continuously adapted to the requirements and supplemented with optional functions and modules.
THE KEY FEATURES
Type Approval in accordance with IMO Resolution MEPC.107 (49)
In compliance with LDNV TAP 771.60, Clean Design
Optional with type approved FSU® By-pass Function
Capacity from 150 l/h up to 10.000 l/h
Jet-wash oil drainage
Compact design and easy installation
Pump can optionally be used as separate transfer pump
Also available in DVZ Stainless Steel Design
“DVZ-BMSU” - BIOMASS SEPARATION UNIT (MEMBRANE UNIT)
The membranes of the Biomass Separation Unit “DVZ-BMSU”, which are made of a special titanium alloy, can rightly be described as almost indestructible. Due to its 100 % stainless steel construction and the deliberate avoidance of materials such as plastics and ceramics, this unique membrane technology is insensitive to high pressures and temperatures, as well as critical pH ranges. A key feature that also makes the modules of the “DVZ-BMSU” unique is “CIP” (Clean-in-Place). Here, the modules are individually decoupled from the treatment process and run through a cleaning process. During this, the sewage treatment plant remains in operation (min. two membranes).
The membrane modules are arranged outside the reactor chamber or tanks so that they are always easily accessible, easy to maintain and can be quickly replaced in exceptional cases thanks to a special quick coupling system. It is never necessary to open the treatment plant, as it is the case with submerged membranes, for example.
Due to the possibility of returning the membrane modules to “new delivered condition” through this cleaning process, an extremely long service life is realised (>20 years achievable) and the necessity of continuously changing the membranes is eliminated.
By using the “DVZ-BMSU”, which operates on the basis of the cross-flow principle, we achieve a continuous permeate quality where we consciously speak of clear water instead of “just” clean water!
The addition of disinfectants for final treatment, such as chlorine and even UV treatment, is not necessary in any case.
“DVZ-BMSU” units can also supplement existing waste water treatment plants as an additional process stage or installed downstream.
DVZ-FT - FAT TRAP
Grease and oil from the galley shall not lead into a sewage treatment plant as they have a negative impact on the treatment process and can lead to clogging.
DVZ-FT Fat Traps ensure reliable separation of fats and oils and are available in various sizes.
THE KEY FEATURES:
Easy installation
Compact design
Serval types and capacities
Heating device (optional)
Galvanized or Stainless Steel
Also available with Automatic Grease Discharge
DVZ-JZR “BIOMASTER”® - BIOLOGICAL SEWAGE TREATMENT PLANT
Modern, innovative, highly efficient and reliable sewage treatment ... this is what our DVZ-JZR “BIOMASTER”® combines in one high level system.
The interaction of our key technologies DVZ-JZR (Jet-Zone-Reactor) and DVZ-BMSU (Biomass Separation Unit) forms the unique sewage treatment system DVZ-JZR “BIOMASTER”®, which sets new benchmarks in sewage treatment.
A wide range of options tailored to the sewage treatment system, such as a fully automatic pre-filter unit or an anti-foam solution, result in a holistic solution.
The high flexibility and the modular design allow the system to be optimally adapted to customer specifications and the conditions in the engine room.
Process stages and other components can be divided to the extent that final assembly in the engine room is possible, eliminating the need to open the hull to replace the treatment plant.
This also makes it possible to (re)equip existing tanks with the DVZ-JZR (Jet-Zone-Reactor) and thus convert them into the first process stage.
