Improved technology for water treatment with ROCHEM MBR Membrane Bio Reactor

The combination of a high density biomass reactor with the UF module system for ultrafiltration forms the operating unit of the Membrane Bio Reactor ROCHEM MBR which gives many advantages for waste water treatment.

Rochem Solution

The efficiency of the Membrane Biological Reactor allows for the purification of black water on ships to achieve a quality superior to the international limit values for contaminants imposed by MARPOL/IMO.

Therefore the environmentally sound purified waste water can be discharged overboard in any harbor or coastal area.
Rochem RO systems are designed to fulfil all Naval requirements,such as:

  • Shock-and vibration resistance
  • EMC
  • Airborne noise emission
  • A-magnetic design, etc.

according to NATO STANAG regulations

Capacity: 25 m³ / day


fitted in Italian Navy FREMM Frigates
For the treatment of
Black Water, Accommodation Grey Water,
Laundry Water and Galley Grey Water
