News & Innovations


Water treatment specialist DVZ-GROUP has introduced the DVZ-JZR "BIOMASTER"®-OFFSHORE-UNIT, a compact and sheltered sewage treatment module designed and built in accordance with the highest offshore standards and able to operate in harsh environments. The system incorporates the company’s sewage treatment system DVZ-JZR "BIOMASTER"® and is type-approved in accordance with the latest IMO Resolution MEPC.227 (64).

The high-performance JZR bioreactor (Jet-Zone-Reactor) employs a newly developed aeration technology that operates on the injector principle for the treatment of waste-water in the plant-specific biological cleaning stage. Due to the high throughput and compact construction of the reactor, this treatment technology requires very little space. For designers, this means the greatest possible flexibility for integration into the ship.
