The Alfa Laval MSPX 303 system offers a fully integrated andmodularized system for the de-oiling and de-sludging of oilywaste. The reduction of oil content with this system securesthe efficient operation of your bilgewater system.

ApplicationThe MSPX 303 Sludge Treatment System is designed tohandle sludge from oil treatment systems in diesel engineinstallations.

The sludge consists of a mixture of water, oil and solids. In the MSPX 303 separator this mixture is separated into its main constituents.

System conceptThe key components of the MSPX 303 Sludge TreatmentSystem are:

• MSPX 303 separator.• HEATPAC EHMS electric heater or S/T heater.• EPC 41 control unit.• Feed pump.• Starters for separator and feed pump.• Double strainer.• Conditioning module MP 205 (optional).

Features MSPX 303 separator• Separation of oil, water and solids simultaneously from

oil sludges of varying composition and density withoutadjustment.

• Integral paring disc pumps for continuous discharge ofseparated oil and water.

• Unique separator bowl design.• Separate outlets for oil, water and solids.• Automatic start and stop sequence.

Benefits• Substantial savings in total sludge handling cost.• Maximum separation of water prior to discharge to the

collecting tank.• Maximum recovery of oil for direct use in boiler or for

incinerator disposal.• Minimum sludge accumulation in bowl ensures long

intervals between service.

Throughput capacityThe throughput capacity of the system is from 200 l/h to500 l/h dependent on the use of separation conditionerMP 205.

System working principleSludge is pumped from the sludge tanks and fed via theheater to the MSPX 303 separator. An eccentric screw pumpis used to ensure the optimal feed rate to the separator.

As an option to enhance the performance of the system adosing unit for injection of separation conditioner MP 205 isused. The MP 205 is fed directly before the feed pump in theMSPX System. By doing this, the MP 205 will be thoroughlymixed into the feed as it passes through the feed pump andthe heater. We recommend dosing MP 205 at a rate of250–500 ppm of the feed flow when dosing directly into the feed.

A constant temperature of 95°C is maintained by theHEATPAC heater with an accuracy of ±1°C. The MSPX 303separator and the MP 205 dosing unit are connected to anEPC 41 control unit for fully automatic operation anddesigned for intermittent discharge of separated solids duringoperation. Water and oil are removed continuously, solidimpurities intermittently.

Since the MSPX 303 system is supplied as three completemodules with a total footprint of approximately 2 m3 it caneasily be installed onboard any vessel or in any power plant.

Operations• A preventive maintenance program is available with three

versions of spare parts kits corresponding to three levels of service:– Intermediate service kit – every third to fourth month.– Major service kit – once a year.– Three year service kit – every third year.

• System manual includes detailed information in electronicformat or paper copy:– Installation instructions.– Operating instructions.– Alarm & fault finding.– Service & spare parts.

• Commissioning & technical service is available from allAlfa Laval offices to start-up the system and to adviseabout operations & maintenance.

• Training in all aspects of oil treatment, fresh water genera-tion and cooling is available.

• All services are incorporated in specially tailored NonstopPerformance packages, details are available from localAlfa Laval offices.
