STP Series Marine Sewage Treatment Plant
Principle Description
This 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, biologically and cleanly to ensure the effluent can meet the requirements of the resolution MEPC.159 (55) and other much harsher requirements.
Treatment Flow
sewage inlet -> aeration -> contact oxidation -> sedimentation -> membrane tank -> disinfection -> effluent
Specification
- Adopt round tube design, both ends circular head, pressure resistance, compact structure.
- Loading with automatic control, 24 hours unattended operation.
- Adopt “MBR” technology, making the equipment small, solving the problem of large volume of traditional process.
- The equipment is installed in the cabin, with good sound insulation and noise reduction.
- The equipment adopts imported membrane components and hollow fiber membrane technology, solving the problem of “aerobic-anoxic”, and realize the problem of “nitrogen and phosphorus removal”.
- The membrane tank and the aeration tank are separated, the sludge is transferred from the sedimentation tank and membrane tank to aeration tank, means 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” using technology patent.
- The effluent after further treatment can be reached at the requirement of “water recycle”.
STP Series Marine Sewage Treatment Plant belongs to the key devices for prevention of pollution from ships in seas and 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 MEPC159(55). The device also can be used in terrestrial sewage, besides in ships and oil platform. The water quality after treatment can reach the national discharge water quality requirements. It is also applicable to treat the galley, shower drainage which is called “grey water” on condition that the “grey water” is pretreated and there should select a bigger capacity model to match with.
This device has obtained one item of Authorized Patent and one item of Practical new patent, meanwhile has also obtained the Type Approval of CCS and IMO circular in April 2009, and it is February 2011 by Germanischer Lloyd (GL) type approval certificate MED made, while providing ABS, DNV, BV, RS and other classification societies certificate.
