DVZ - JZR "BIOMASTER"® CRFBiological Sewage Treatment Plant

Key Features

Scalable, divisible and customisable like no other, the DVZ-JZR “BIOMASTER”® system is also the perfect solution for higher passenger numbers such as on (smaller) cruise ships, RoPax and ferries.

  • 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.
  • Fulfills 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.

Due to the variable number of Jet Zone Reactors DVZ-JZR and Biomass Separation Units DVZ-BMSU, the system can easily be 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 to the available space in the ship’s hull in this application. Of course, customers and users also benefit.
