Biological sewage treatment plant

Company: DVZ-SERVICES GmbH

Product: Biological sewage treatment plant

The protection of the environment and conservation of safe quality water for ourselves and next generations is still of growing importance. On the other hand, cost effective solutions are more than ever of vital interest for both fleet owners and the shipbuilding industry. To meet the present demands and meanwhile providing flexibility in design, a new line of "Biological Sewage Treatment" system is developed.

1. Inlet sewage
2. Blower
3. Airlift
4. Fixed media
5. Vent
6. Spillover
7. Disinfection tank
8. Disinfection pump
9. Discharge pump
10. Level switches
11. Sludge storage area
12. Air scour system

Operating principle:

The wastewater enters the system via the inlet (1). The blower (2) provides air and circulation of the wastewater over the submerged bio-filter (4) by means of the simple and reliable mammoth-pump principle (3). The micro-organisms that grow on the surface of the media are biologically breaking down the organic matter in the wastewater. The treated water flows over through the spillover connection (6) to the disinfecting tank (7). The disinfecting pump (8) is metering the liquid disinfectant accurately, to eliminate the remaining bacteria. High treatment coefficients and good quality effluent is produced, suitable for safe discharge overboard. The discharge pump (9), and level switches (10), automatically maintain the level in the disinfecting tank. The low amount of sludge formed is collected at the bottom (11) and can be flushed out with air (12) and pumped out by the discharge pump (9).

The features of our new DVZ-MS-II series are:

  • Type approval certificate from Lloyd's Register of Shipping and See-Berusfsgenossenschaft, IMO/MARPOL certificate, accepted by USCG and many other authorities.
  • Flexible design to fit any ship.
  • Skidmounted standard units.
  • Modular units (ideal for retrofit).
  • Short, reliable delivery time.
  • The most compact biological process: low sludge production, simple and reliable process control by our "fixed activate sludge technology " (FAST).
  • Integration with our Vacuum Toilet System, or Vacuum Collecting System, offers you guarantee for trouble free operation and most practical dimensioning.
