The Holland
Marine services sewage treatment process is inherent
self regulating. There are no adjustments, the unit will
handle any shipboard sewage.
No pretreatment, maceration or screening is required.
Application of fixed media permits formation of much larger
biomass volume than would otherwise be possible in conventional
biological systems. The media itself is virtually non
biodegradable. |

OPERATING PRINCIPLE |
| |
|
| |
The waste water enters the system via the
inlet (1). The blower (2)
provides air and circulation of the waste water over the
submerged biofilter (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 waste water. The treated water flows over
through the spillover connection (6)
to the disinfection tank (7).
The disinfection pump (8)
is metering the liquid disifectant accurately, to eliminate
the remaining bacteria. High treatment coefficents and
good quality effluent is produced, suitable for safe discharge
overboard. The discharge pump (9)
and level in the disinfection 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). |
