EC approved Compact Marine Sewage Treatment Plant

EC approved Compact Marine Sewage Treatment 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",to meet the effluent standards of IMO.MEPC.159(55),and discharge the effluent overboard.This device is according to the resolution MEPC.159(55), enacted on 13 October 2006.The convention(MARPOL 73/78) provides that all STPs installed on board on or after 1 January 2010 should meet the resolution MEPC.159(55).

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 bigger capacity model to match with.

IMO Approval

Meet resolution of MEPC.159.(55) enacted on October2006.

Used for seaport,dock,industry,petroleum ,various vessels

Principle Description

The device adopots the principle of Activated Sludge,Bio-contact Oxidation and Menbrane Biological Reactor(MBR) to digest organic pollutant.MBR can treat organic pollutant effciently,drastically and cleanly to ensure the effluent can meet the requirments of the resolution MEPC.159(55) and other much hasher requirments

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 bio-membrane 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 "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 dowm.Due to back flushing and clean the membrane "online" usd technol;oge patent.

6."On-line" 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".
