This means for processing waste water and sewer board toilet (also known as Blackwater), so as to reach the international emission standards to side at discharge. This device can also be used on board from the kitchen and bath gray water treatment, but the gray water should be pretreated and selection of larger capacity unit match. Marine sewage treatment plant to prevent the case IMO International Ships "MARPOL 73/78" Annex IV of MARPOL Convention critical equipment. The current emission standards and performance criteria test is December 3, 1976, issued MEPC.2 (VI) resolution (known as the old standard), this series device complies with MEPC.159 October 13, 2006, issued (55) resolution (known as the new standard), irrespective of the provisions of the Convention to all lifting marine sewage treatment plant on the old and new ships should meet the new standards from January 1, 2010. Multi-level marine sewage treatment plant using activated sludge, contact oxidation and membrane bioreactor (MBR) treatment principle digestion of organic pollutants. MBR can achieve efficient, thorough and cleanly sewage treatment, so that the discharge water to meet the new IMO standards and other more stringent requirements. Products provide CCS certificate and EC certificate of the device is a patented product with independent intellectual property rights innovation. Summary of the various rules and emission standards are as follows: IMO IMO old standard new standard USCG Alaska TSS (mg / l) 50 35 150 30 BOD5 (mg / l) 50 25 No 30 COD (mg / l) 125 No No No coliform requirements (a / 100ml) 250 100 200 20 PH 6 ~ 9 6 ~ 8.5 No 6-9 residual chlorine (mg / l) as low as possible <0.5 No 10 type test several days (days) 10 10 10 30 Jiang Su Bairui Special Trade Co.
