MEPC159(55) resolution, Marpol 73/78, low consumable
Marine Sewage Treatment Plant belongs to the key devices for prevention of pollution form 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 STP, which is called “old standards”. This device is according to the MEPC.159(55) resolution enacted on 13 October 2006, which is called “new standards”. The convention (MARPOL 73/78) provides that all STPs installed on board on or after 1 January 2010 should meet the MEPC.159(55) resolution.
Summary all the rules and effluent standards as followings:
| IMO Old standard | IMO New standard | USCG | Alaska |
TSS (mg/l) | 50 | 35 | 150 | 30 |
BOD5 (mg/l) | 50 | 25 | NR | 30 |
COD (mg/l) | NR | 125 | NR | NR |
coliform (per 100ml) | 250 | 100 | 200 | 20 |
PH | 6~9 | 6~8.5 | NR | 6~9 |
Residual chlorine (mg/l) | NR | less 0.5 | NR | 10 |
Duration of type approval test (days) | 10 | 10 | 10 | 30 |
The SWCM type marine sewage treatment plant uses activated sludge, contact oxidizing and principle of biologic membrane to digest the organic pollutant, which can treat sewage effectively and reach at the IMO new effluent standard or other stricter requirements.
The device is patent product, provided with independent innovation intellectual property.
