Marine Sewage Treatment Plant

Summary

Marine Sewage Treatment Plant belongs to the key devices for prevention of pollution form ships in seas. 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 wastes from the toilets on vessels and also called “black water”, to meet the effluent standards of IMO. MEPC.159（55), and discharge the effluent overboard .

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 and cleanly to ensure the effluent can meet the requirements of resolution MEPC.159 (55) and other much hasher requirements.

Marine sewage treatment device will containing ship sewage into collection buffer in the cabinet and crushing by crushing pump, then pumped into the sequencing batch cabinet "water - aeration - sedimentation, drainage, leisure," the integration of control processing program, after treatment MBR, through the ultraviolet sterilization can fully match IMO.MEPC 159 (55) resolution standard requirements.
