Marine Sewage Treatment Plant (According to new standards)

Marine Sewage Treatment Plant(STP) is used to treat the sewage, which means human body wastes and the wastes from the toilets on vessels (so called "black water"), to meet the effluent standards of IMO MEPC.159(55) before discharging the effluent to overboard. It is also applicable to treat galley and shower drainage (so called "grey water") on condition that the "grey water" are pretreated and a bigger capacity model of the plant is selected.

Marine Sewage Treatment Plant belongs to the key devices for prevention of pollution from ships in seas and oceans according to the revised Annex IV of the International Convention of the Prevention of Pollution (MARPOL 73/78). The MEPC.2 (VI) resolution adopted on 3 December 1976 is the present guidelines on implementation of effluent standards and performance tests for Sewage Treatment Plant, which is called "old standards" .

Our STP is designed and manufactured according to the MEPC.159 (55) resolution enacted on 13 October 2006, which is called "new standards" which is more strict than the old one. The convention (MARPOL 73/78) requires that all sewage treatment plants installed on board on or after 1 January 2010 must meet the new standards.

The SWCM type marine sewage treatment plant uses activated sludge, contact oxidizing and principle of biologic membrane to dig the organic pollutant, which can treat sewage effectively and reach at the IMO new effluent standard or other even more strict requirements.

The device is patented with independent innovation intellectual property.
