Combined EGR and bilge water separator launched

The innovative solution extends Marinfloc’s established flocculation treatment for bilge water to EGR bleed off water treatment. The solution has been approved by classification society DNV GL and MAN Energy Solutions and fulfils the requirements of MEPC 107(49) and MEPC 307(73).

EGR is used to reduce NOx as per the Tier III requirements when use with compliant fuel. The rules require bleed-off water to be treated to < 15 PPM when recirculating exhaust gas, which is also the requirement for bilge water.

By combining the two treatment systems, ship owners can achieve capex savings and optimise space requirements, without any impact on performance. Marinfloc notes operating costs are also likely to be reduced as maintenance, spare parts and training are needed only for one unit.

The development of the combined solution began in 2016 at MAN Energy Solutions in Copenhagen. Class society DNV GL approved the system design in early 2020.
