Marine SOLAS Approved Sewage Waste WaterTreatment Plant
Application
Marine sewage treatment plant belongs to the key devices for prevention of prollution form ships in seas and oceans according to the revised Annex IV of the International Convention of the
Prevention of Pollution(MARPOL 73/78).This device 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".The device also can be used in terrestrial sewage,besides in ship vessels and oil
platform.The water quality after treatment can reach the national reuse water quality
requirements.It's also applicable to treat the galley,shower drainage which is called"gray water"
on condition that the "gray water" is pretreated and these should select a biggercapacity model
to match with.
Features
ABS, CCS,BV,EC Approval
IMO Approval
Meet resolution of MEPC.159.(55) enacted on October2006.
Used for seaport,dock,industry,petroleum ,various vessels
Principle Description
The device 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 the resolution MEPC.159(55) and other much harsher requirements.
Specification
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 requirment of 24h unattened cabin.
3.Adopting the "MBR" technology,devices allow to the narrow size,and solve the conflict of small
space of carbin,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,meantimes the "pump stops and air never stopped",so as the scale on the membrane surface comes dowm.Due to back flushing and clean the membrane "online" usd technol;oge patent.
6."Online" cleaning technology,making the dirt on membrane off automatically,recover membrane
flux.It can be solved the problem of openning the cleaning or replacement of the membrane
difficultly caused by the small space in cabin.
7.The effluent after further treatment can be reached at the requirment of "water recovery".
