MARPOL liquids
MARPOL (marine pollution) oils are effectively all oils that are produced as a waste product during a ship’s operation. In practice, MARPOL oils are primarily those that contaminate bilgewater or tank wash water. MARPOL oils can, however, be reused as fuel following a simple treatment process.
Environmentally friendly treatment
GEA offers the decanter and self-cleaning separator technologies that effectively separate the waste into water, solids and oils.Using our technology, disposal companies in ports benefit from an efficient treatment that turns a waste product into a sought-after raw material.
Separated oils with a high calorific value
Using GEA decanter centrifuges to separate the MARPOL oil can generally reduce the solids content down to 0.2 per cent, and the content of free water to less than 1 percent. Downstream of this initial decanter separation, GEA separators remove the finest solids and the residual water. The separated oil can then be sold as a fuel with a high calorific value. Recycling the oils also reduces disposal costs. The separated water phase can be treated further in a waste water plant, but it is clean enough to be returned straight to the environment.

3-Phase Separating Decanter
The 3-Phase Separating Decanter is a centrifuge in which two liquids of different densities are separated from each other. At the same time solids are separated and discharged.
Clarifier
The clarifying centrifugal separator is used for separating solids out of a liquid. The separator is equipped with a stack of conical disks for creating a large equivalent clarification area in a relatively small bowl volume.
Clarifying Decanter
Clarifying decanters are designed for the continuous separation of suspensions into solids and clarified liquid, without interrupting the feed of the suspension.
Separator
The separating centrifugal separator is a machine in which two liquids of different densities are separated from each other. Solids may also be separated at the same time.
