MEPC.159(55) 20 PERSONS WITH IMO APPROVED TYPE MARINE SEWAGE
TREATMENT PLANT
Meetresolution of MEPC.159.(55) enacted on October2006.
CCS,EC.BV ETC....
IMO Approval
Ship Bilge,port,dock ...
Features
1.Adopting horizontal circular design, ellipse closures on both ends,
pressure resistance and compact structure.
2.The device is adopted auto-control, and compliance with the
requirement of 24-hours unattended cabin.
3."MBR" technology, allow devices to narrow the size, and solve the
conflict of small space of cabin, but big volume of device.
4.The intermittent aeration in biomembrane tank and hollow fiber
membrane tank, form the process of "aerobic - anoxic", and resolve
the problem of "nitrogen and phosphorus removal".
5.The device is adopting the principle of airlifting to transfer the
sludge from sediment tank and membrane tank to aeration tank,
mealtimes 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 USD technology patent, so the life of membrane can
be prolonged at least 8 to 9years.
6."Online" 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.
7.The effluent after further treatment can be reached at the
requirement of"water recovery"
Performance
* Capability of disposed sewage
a) Black water:excrement and urinefrom toilet
b) Gray Water: waste water form cooking room and bath room
*It Can be developed to a sewage recycling system
