3. 1. Introduction
Purpose is to clean fluids
Different cleaning methods

4. 2. Usage of separators 2.1 Industry separators 2.2 Marine separators
- Crude oil product
- Food industry (edible oil,
milk)
- Pharmaceutical
- Chemical
- Petrochemical processes
- Treatment of industrial fluids
2.2 Marine separators
- HFO
- Lubricating Oil
- Bilge oil separator
- Evaporating water separator

5. 3. General information about marine separators
Bowl rotating and centrifugal force
Gravity disc
Water seal
Operating water
Water for rinsing

6. 4. Fuel oil and lubrication oil separators
Purifier eliminates contaminants
Clarifier eliminates high density impurities
Why is it important to separate HFO and LO?

7. 5. Parts 1: Product feed, 2: Disc stack, 3: Separating disc,
4: Concentrate chamber, 
5: Nozzles, 
6:Centripetal pump for light phase, 
7: Discharge of light phase, 
8: Centripetal pump for medium phase, 
9: Discharge of medium phase, 
10: Feed for wash water or concentrate recycle

8. Bowl
Disc stack & Distributor

9. Paring disc
Gravity discs
Heater

10. 6. How it works The contaminated product is pumped to the separator
Separation takes place inside a rotating
bowl
Light phase is discharged through
the outlet pipe
Water forms a seal around
the outer edge
The solids collect in the periphery
where they are discharged

11. 7. Troubleshooting and maintenance
Emulsion
Suspension
Unsuitable gravity disc
Deposit accumulation
Maintenance and repair manual

12. 8. Conclusion Simple handling and maintenance
Greater security of facility
Lower operation costs
