Marinfloc has introduced its combined Exhaust Gas Recirculation Bleed Off water treatment system and Bilge water separator.
The solution is approved by both DNV GL and MAN Energy Solutions and fulfills the requirements of MEPC 107(49) and MEPC 307(73). The approval means that only one separator is required instead of two. Reducing the amount of equipment needed on a vessel will provide shipyards, engine makers and ship owners with a significant cost saving solution.
Exhaust Gas Recirculation (EGR) is used to reduce NOx as per the Tier III requirements when use with compliant fuel. The EGR process will generate a portion of bleed off water that must be treated to < 15 PPM which is also the requirement for bilge water. By combining the two treatment systems, the capital expenditures will be reduced without negative impact on performance. Additionally, there will also be a welcome reduction in operating expenditures as maintenance, spare parts and training are needed only for one unit.
The system is based on Marinfloc’s flocculation technology. The Whitebox is included as standard to segregate the waste streams, to eliminate cross contamination and record all activities. Moreover, the Whitebox fulfils the EXXON requirements and is Marinfloc’s recommendation on all US calling vessels.
The development of this solution started back in 2016 at MAN Energy Solutions facilities in Copenhagen and concluded when DNV GL approved the system design in early 2020.
