SOLAS Approved MARPOL IMO MEPC.159(55) Standard 50 Persons 3800L/D
Marine Sewage Treatment Plant
1. Application of SOLAS Approved MARPOL IMO MEPC.159(55) Standard
50 Persons 3800L/D Marine Sewage Treatment Plant
This MBR Waste Water Treatment Plant For Vessel is applicable to
treat the sewage, which means human body wastes and the wastes from
the toilets on vessels and which is also called "black water", to
meet the effluent standards of IMO MEPC. 159(55), and discharge the
effluent to overboard. It is also applicable to treat galley &
shower drainage which is called "grey water" on condition that the
"grey water" should be pretreated and should select a bigger
capacity model to match with.
2. Standard of SOLAS Approved MARPOL IMO MEPC.159(55) Standard 50
Persons 3800L/D Marine Sewage Treatment Plant
MBR Waste Water Treatment Plant For Vessel belongs to the key
devices for prevention of pollution form ships in seas and oceans
according to the revised Annex IV of the International Convention
of the Prevention of Pollution (MARPOL 73/78). The MEPC. 2 (VI)
resolution adopted on 3 December 1976 is the present guidelines on
implementation of effluent standards and performance tests for STP,
which is called "old standards". This device is according to the
MEPC. 159(55) resolution enacted on 13 October 2006, which is
called "new standards". The convention (MARPOL 73/78) provides that
all STPs installed on board on or after 1 January 2010 should meet
the MEPC. 159(55) resolution.
3. Principle of SOLAS Approved MARPOL IMO MEPC.159(55) Standard 50
Persons 3800L/D Marine Sewage Treatment Plant
The MBR Waste Water Treatment Plant For Vessel adopts the principle
of activated sludge, bio-contact oxidation and membrane biological
reactor(MBR) to digest organic pollutant. MBR can treat organic
pollutant efficiently, drastically and cleanly to ensure the
effluent can meet the requirements of resolution MEPC.159(55) and
other much hasher requirements.
4.Characters of SOLAS Approved MARPOL IMO MEPC.159(55) Standard 50
Persons 3800L/D Marine Sewage Treatment Plant
A. Adopting horizontal circular design, ellipse closures on both
ends, pressure resistance and compact structure.
B. The MBR Waste Water Treatment Plant For Vessel is adopted
auto-control, and compliance with the requirement of 24-hours
unattended cabin.
C. Adopting the "MBR" technology, devices allow to the narrow size,
and solve the conflict of small space of cabin, but big volume of
device.
D. The intermittent aeration in bio-membrane tank and hollow fiber
membrane tank, form the process of "aerobic-anoxic", and resolve
the problem of "nitrogen and phosphorus removal".
E. The compact marine sewage treatment plant is adopting the
principle of "air-lifting" to transfer the sludge from sediment
tank and membrane tank to aeration tank, meantimes the "pump stops
and air never stopped", so as the scale on the membrane surface
comes down. Due to back flushing and clean the membrane "online"
used technology patent so the life of membrane can be prolonged at
least 8 to 9 years.
F. "On-line" cleaning technology, making the dirt on membrane off
automatically, recover membrane flux. It can be solved the problem
of opening the cleaning or replacement of membrane difficultly
caused by the small space in cabin.
G. The effuent after further treatment can be reached at the
requirement of "water recovery".
