Features

Patented Multi-PhaseEmulsion Breakertechnology

No chemicals needed Continuous cleaning

without backflushing

No adsorption ormembrane filtersrequired


8/23


Benefits for shipyards

Pre-mounted system for easy installation

Complete delivery, including harbour control valve,dry-run protection and overboard non-return valve

Easy commissioning and initial start-up

Flexible designs for different engine room designs


9/23


Benefits for shipowners

Reliable, easy-to-operate system providescontinuous operation with automated control andmonitoring system

High separation efficiency, thanks to the patentedprofiles and emulsion foam breaker elements

Reduced operating costs, thanks to automatedcontrol, low maintenance, minimal spare parts and

low fresh water consumption

Reduced waste disposal costs, thanks to reducedoily waste volumes and no special waste

Stage 1Multi-Phase Separator (MPS)

Uses patented profiles to separate oil and solids

Coalesces small oil droplets to larger droplets

Transfers separated oil fordischarge to waste oil tank

Solids drained tosludge tank

Directs oily water toStage 2 for furthercleaning

MPS


13/23


Stage 2Mechanical Emulsion Breaker (MEB)

Uses patented Emulsion Foam Breaker Elements toseparate the finest mechanically emulsified oil droplets

Coalesces fine oil droplets to larger ones through use

of microfiber bed

Transfers separatedoil for discharge towaste oil tank

Directs cleaned waterto outlet for ppm valuecheck and discharge MEB

Principle ofother make

Comment MPEB deoiler

Backflushingsystems

The gravity coalescer tank oftenneeds many backflushing (cleaning)interruptions with fresh water

Generates a lot of waste oil withhigh water content

Real capacity lower than nominalcapacity due to the backflushing

NO backflushing

Chemicals Creates a lot of waste, ca 1525%of bilge water, to be disposed ofashore

NOchemicals

Comparison with other cleaning principles


16/23


Principle ofother make

Comment MPEB deoiler

Adsorptionfilter

Good final stage polishing effect

Requires frequent replacement

before filter is full, otherwise oilwill break through

NO adsorptionfilter

Active carbonbed

Good final stage polishing effect

Mostly used for drinking watersystems, not for oil cleaning; feedshould contain only few ppm (1020)

to obtain acceptable life length

Sensitive to solids

Requires many man-hours forfrequent replacement and disposalAlso dirty to change

NO active carbonbed

Comparison with other cleaning principles

Standard pump configurations

Flexibility to meet your needs

Built-on or separate pump

Dry-run protection as standard

Special design of stator and rotor configurationto minimize the creation of emulsions


21/23


Oil-in-water monitorOMD 2005

Continuously monitors ppm value of cleaned water

Continuously displays ppm value

Automatically recirculatescleaned water exceeding15 ppm back to bilge tank

Stores values for18 months
